Title: Projection lenses
Post by: Dr Klaus Schmitt on July 03, 2016, 14:42:37
Anyone here using projection lenses as taking lenses? I have developed quite a taste for those and use
them quite often for my flower works...

A rather strange Rodenstock Projection Lens (Petzval type) to start with...

a bit odd and unusual and people are looking ;-)

This is what I use to mount such lenses:

These type of lenses in general are indeed quite rewarding, after having mastered their razor thin DOF, with rich colors, great contrast and very smooth and creamy bokeh!

They can still be found for rather small amounts, yet prices are increasing fast over the last months, the phase where they were neglected sleepers is over, so I cannot more than emphasize to start now with this quite different type of photography if so interested!!

Lovely images. How do you mount it on the camera?
I have a Colorplan, bought it to replace the Hector 85/2.8 lens that came with my Leica/Pradovit projector. In the shop I had the chance to compare both lenses side by side, the Colorplan was noticeably crisper and brighter. I sometimes wondered if I could use the Colorplan for photography, if it were placed in a flexible mount it should be possible to use it as a tilt-lens ...

Sharpness and contrast are IMHO outstanding for far away objects for a f1.9 projection lens, of course there is quite a bit CA.

It does work closer up, but not optimized for this:

This is pictorialism.  Achieved, as it was in the late nineteenth and early twentieth centuries, by the lens' image forming qualities.  A pleasing break from the look of computer-designed exactness.

Red bleeding?? Please elaborate...

Often we talk about bleeding when one colour unintentionally blend into another. In this case the red is literally 'bleeding' into the yellow in a very natural way,,,

What a rather cold expression when talking about beautiful flowers, how much does one have distanced
oneself from nature's beauty to use such terminology? I just wonder...

After seeing these images i wanted to try some can you give me any advice on method etc. I purchased a cheap projector lens and gave it a go the depth of field seems to be very thin. Have included a take  i sharpen and de noised any comments would be helpful

Thank you Klaus that was a $3 projection lens purchased from surplus shed.It was a playtime shot hand held in breeze  I have just ordered a 85mm lumo lens should arrive at the bottom of the world in about 3 weeks. you seem to get quite a good depth of field in some of your shots. Wondering if you had any tips for its use.
I just loved the appearance of your flowers
The lens measures 1/2 x 1 and a quarter inches mounted on a striped out sliding zoom (no glass) (it still has aperature controll)
Thank you for any help or ideas you can give me ( at 82 running out of time)

It is a metaphor.  It is no different to talking about "rays" of light or "focusing" a lens - or "nature's beauty".  As long as we remember it is a metaphor no harm is done.

As I shoot only fully open, the DOF is simply determined by the distance away and the focal length of then, lens and its f-stop. Just play with it and you'll soon get a grip on that. 85mm is quite a useful focal length, gives you enough working distance for flowers as well as portraits, if you like that.

Thanks, quite amazing what this lens from an abandoned micro projection system delivers ;-)
If I'm not mistaken by the reflections, it is a 5e/5g design, most likely a modified Double Gauss.
Other images show that it is nearly apochromatic, with hardly any visible CA.

for sure, rather from some other optical (projection?) system, but funny to play with it. Wonderful sunny spring day it was...

Just like the other lenses, this Carl Zeiss Jena 150mm also separates the sharpness and the bokeh really well.

Also, I always appreciate that your images are richly saturated without being over-saturated.  Except for the post process technique, what is the key to that?  Do these projection lenses in general allow that saturation?  Which camera do you use?

Akira, I have set my camera and my very simple PP routine to match how I see my world. I use Panasonic LUMIX cameras GH1/GH2/GH4 mainly, this one was shot using a GH1.

Projection lenses are generally sharp, and have good to high contrast (except some quite old ones) as this was needed to project high quality films to the pleasure of an audience in movie theaters. Most of the modern ones use (modified) double gauss lens schemes and have modern multi-coatings.

Thanks, Klaus, for the disclosure.  It is well understandable that the projection lenses offers high contrast images, as they are designed to work in the harshest lighting conditions!  :D  But the rich color saturation can be an added bonus.

I loved my GH2 and GX8.  Panasonic cameras seems to have some hidden treasure...on condition that they are used masterfully.

I have a few, but there are so many on the market which have been made by different lens makers.
Basically all optical companies have made them since decades if not centuries, dating back to Petzval
which still is a very common lens design for projection lenses. There are still discoveries to be made
and cheap ones to be found (especially russian ones), although the prices went up considerably since
the "hype" started and I also plead guilty for that trend... ;-)

You could do same Paco, just need some 65mm focusing helicoid, two adapters (one camera, one lens)
and a rather cheap russian projection lens, and you're all set to go!

No, this is a much later one, I mean the original brass Hermagis projection lenses not SOM. It might still be Petzval scheme.

SOM Berthiot ("Société d'Optique et de Mécanique"), founded 1857, bought teh muck older company HERMAGIS, founded 1845, in 1934 and integrated them into their business, so Hermagis disappeared and was just used as a brand name by them later.

front lens curvature and working w/o sun shade against the sun helps to create such effects ;-)

Cannot compare those, the VISIONAR is the latest and best Carl Zeiss Jena projection lens they ever made, with very high resolution and contrast (avaliable up to a f1.9/200mm). It is quite an elaborated double gauss lens, optimized for larger distances, but suprising well behaved if used for close ups. Also works very well with speedbooster.

I was rummaging in the barn and remembered that back in about 1951 my dad bought a rather exotic German microfilm reader, which I have ended up with.  It took a reel of 35 mm. microfilm and projected it on either its own fold-out screen or, with a trick 90 degree attachment, on a wall or ceiling. Anyway, it has a Steinheil 60 mm. F4.5 Culminar as its main lens, and it occurred to me to try it out.  I bodged up a mount with a piece of a zoom lens and a piece of Exakta extension tube and a couple of setscrews.  The DOF is terribly shallow, it's hard to hold steady, and it's not ideal for focusing without bright lights, being so dark, but it has a kind of nice look to it.  I probably will put the microfilm reader back together, but thought I ought to throw this one into the general projection lens roundup....

These are with a D7100, unassisted daylight, and even with live view the focus is pretty iffy.  Very little room for error.

Well Robert,

I guess I know a bit what you are after and I would recommend to start with something rather less expensive and see if this is "yours".

Have a look here https://www.flickr.com/photos/kds315/sets/72157670428350566 (https://www.flickr.com/photos/kds315/sets/72157670428350566), this is a russian sharp, but not expensive projection lens f1.8/100mm which covers FF, a double Gauss design, which I find rather pleasing. It has a rather long back focal distance, so a Nikon camera should be no problem to adapt it to. It needs such a lens, a lens adapter ring, a focusing helicoid and a camera adapter ring, all available on ebay for not much $$.

I recommend to use my modular method described here: http://photographyoftheinvisibleworld.blogspot.de/2015/09/how-to-modularily-mount-projection-or.html (http://photographyoftheinvisibleworld.blogspot.de/2015/09/how-to-modularily-mount-projection-or.html) just with a shorter helicoid.

If this then works for you, you would be able to mount a variety of other lenses to it (as I have done and do), possibly just needs a different lens adapter ring.

What would you think of that?

MEOPTA 1.7/109mm projection lens on Panasonic GH4
Title: Re: Projection lenses
Post by: Seapy on January 05, 2018, 11:14:13
Klaus, can you please explain to me why #1 has clearly defined circular highlight rendition, despite being well beyond the plane of focus, this troubles me, visually and because I don't understand it.  The remaining images have much more natural and pleasingly smooth transition of tones even with moderately colour and saturation contrasty edges despite the background being closer to  the plane of focus.  Although I do notice some other higher luminance contrast out of focus edges seem more clearly defined than I might have expected.

The effect in last three images are just what I am hoping for,  sharp clear contrasty subject and the rest a nice, smoothly diminishing background with no visually distracting areas.

It's as though the greater the edge contrast, the greater the acuity, irrespective of distance from the plane of focus.  In #2, just above the central top red leaf are some fonds or bunch of small branches, they seem to be much sharper than might be expected, given their neighbours are nicely blurred.  I guess they could receive attention in Photoshop, but...

Where the luminance edge contrast is low, the bokeh is lovely, when the luminance edge contrast is high the bokeh isn't as nice.

Does this edge sharpness and the sharp circular highlights of out of focus objects vary with lens type?  The circular highlights seem reminiscent of the circular doughnuts of OOF background highlights from reflex telephoto lenses.

I guess with careful choice of camera angle and subject this may be able to be overcome.  However, sometimes that isn't possible in the field, finding the subject in nice condition and accessible is often challenge enough, getting a good angle can be impossible.

Robert, #1 is several meters away (head of a public fountain it is), while all the others shots are close focus! Naturally, the lens behaves very differently then.

Here that location shot with a very different (non projection) lens:

The MEOPTA seems to work very nicely on m4/3 in terms of size, speed, focal length and the possible shooting distance.

Thanks, I usually work close-up, this was a mere test shot for infinity...

The MEOPTA seems to work very nicely on m4/3 in terms of size, speed, focal length and the possible shooting distance.

It was a bit of a risk, it needed to be mechanically worked over to allow for infinity focusing, but the surgery went well.
Now it focuses from quite close-up (approx 0.15 meters) to infinity on my Panasonic GH4. But admittedly working with
a f1.0 lens at close-up is a challenge...

Sure, CRT Nikkor is already challenging enough for the closeups!

It lacks contrast indeed, but I couldn't improve it by PP.
Actually I tried to test this lens for its bubbly background ability and this implies backlit shots. Not really successful so far and I have to work on this purpose... :-\ ;)

I haven't used it yet on my sony next 5.

Title: Re: Projection lenses--Angenieux Types 65 and 86
Post by: Toby on June 15, 2018, 20:00:42
Ah, a subject dear to my heart projection lenses. Let me post a few with the projection lenses that I have. First Angenieux. There are a series of early 35mm projection lenses by Angenieux, all of which are slightly adjustable for focal length. Three types exist, the Type 65, Type 75 and Type 86, increasing in diameter as you go up. The front lens diameter remains the same, and thus the longer the focal length, the slower the lens for each type. I don't know the entire range, but I know that they exist from 85mm to at least 140mm. The shorter ones are more interesting IMO, because of the swirl and character of the bokeh in the shorter ones.

I have a few of these, of which my favorites are the Type 65 85-90mm (effective aperture at 85mm is ~f1.3) and the Type 86 95-100mm (effective aperture at 95mm is ~f1.2). I'll post five examples from each--the first five from the 65 and the last 5 from the 86.

Added note: It turns out that the 65 with super-swirly bokeh has been modified. I had it out of its focusing mount and discovered that the rear cell had been replaced with a doublet from another lens (which one I have no idea.)

Title: Re: Projection lenses--Super Cinephor
Post by: Toby on June 15, 2018, 20:09:44
A recent pleasant discover are the Bausch & Lomb Super Cinephors. These are monster lenses, double gauss design. I have two now, a 5.25 inch and a 6.5 inch, both f1.8. The 5.25 is especially striking for its clarity and sharpness. The 6.5 is also good, but has a bit more glow, indicating, I think, some spherical aberration. These are for 35/70mm film projection.

First four with the 5.25, then two with the 6.5. I just got these before I left Tokyo on assignment, so I just started playing with them.
Title: Re: Projection lenses--a few more
Post by: Toby on June 15, 2018, 20:25:09
I have a bunch of others. One that I like is the Zeiss Kipronar 140mm f1.9. The Kipronars are the cheapest of the three Zeiss series, but I do like the rendering more than with the more expensive lenses, which are a bit too smooth for my taste. The first four are with the Kipronar, for which I paid the princely sum of $70...

Next is one with the Meopta Meostigmat 35mm f1.3 (which only covers 1.5x crop frame)

Next is the Meopta Meostigmat 50mm f1.0, which covers FF but unfortunately only focuses to about 20cm, even on the Sony E mount.

Next is one using a Rokkor 75mm f2.5 projection lens that I found at a local secondhand shop for $20.

Next is a Zeiss Triplet (yes, that is the name), which I reversed, since it was too smooth for my tastes the right way round (85mm f2.8 IIRC)

Next two are with a Taylor and Hobson 3 inch f1.8 lens...but...I got it when I still had my Nikon, and the flange distance was a killer, so I used only the front element group, making it something like a 135mm f3.5 effective lens with a lot of aberration. However this particular lens has quite an interesting rendering used that way. I like it anyway--you be the judge.

Hi, Toby, welcome to NG!

All images are amazing, but the last two by the front elements of T&H 3inch/f1.8 are the most impressive.  The combination of the sharpness and the shallow DOF is just stunning!
Title: Re: Projection lenses
Post by: Toby on June 15, 2018, 23:51:15
I do love the T&H front element rig. Sharpness drops drastically off axis, but otherwise it wouldn't have that bokeh. So you need some element more or less in the center for sharpness. A bit frustrating for composition sometimes, but hey, no traction without friction...Here are a few others with that lens, just for fun.

Excellent stuff Toby, also thanks to your very clever post-processing and micro contrast enrichment to get those nice bubbles!!

The Angenieux indeed is a killer (it is a f1.4 btw), I found one too in France, quite a pleasure to use (aside with my old 80mm Hermagis lens with similar rendering), both Petzvals. W/o your elaborate post processing results look like this for that Angenieux: https://www.flickr.com/photos/kds315/albums/72157693619188954 (https://www.flickr.com/photos/kds315/albums/72157693619188954)

Those TTH front elements as Akira alfready mentioned are very impressive indeed!!

I have good news for you, the Meopta f1.0/50mm can be worked into a very useful lens for not much cost, even allowing for infinity!!

Hi Klaus!
Thank you for that offer on the 50mm f1.0. I might take you up on it when I finish some big changes that will be happening for me in the next few months.

Yes, the Angenieux is f1.4. I also have a 95-100mm f1.2 (Type 86) of which I posted some stuff earlier in the thread. These are two of my favorite lenses overall for certain things.

I do post-process, using something called Focus Magic (or sometimes Piccure+ but the former is better IMO), then on to Topaz Detail and Topaz Clarity, aside from more mundane corrections.

Thanks for the link to your pix from the Angenieux. I have to say that I think my lens is a bit more "spinto" as the Italians say. I'm posting a couple SOOC that I took yesterday, so you can see what they look like "native."

I had a Type 75 and I have another slightly longer Type 65 that give results more like what you got. I've also found two more Type 65s (cheap!)--a 90-95mm and a 100-105mm that should be at home now and which I look forward to trying out to see what degree of swirl they have.

Lately I've been playing with an Wollensak 3" (75mm) f/1.9 Oscillo-Raptar lens that I adapted.

Here's 3 photos I took with it in the last few days...



Title: Re: Projection lenses
Post by: Toby on June 23, 2018, 20:48:18
I love the Oscillo Raptar. One tip I have is to reverse it, at which point it gets really wild. You may want to stop down to around f2.5 or even f3.5 to tame to bokeh. Here are a couple of examples of the lens reversed. First here is wide open, then at f 3.5, then a couple of others

I recently picked up a Meopta Meostigmat 35mm f1.3. It covers APS-C nicely. None of that aggressively bubbly triplet bokeh. I believe the Meostigmats are double gauss, and this one is quite nice to my eye. This is not aggressively processed.
Title: Re: Projection lenses
Post by: Dr Klaus Schmitt on July 07, 2018, 08:44:18
Yes indeed they are! I have that same lens too, quite a nice performer, not as crazy as the f1.0/50mm but a nice one. Personally the 1.4/70mm is my favorite lens. There also is a (now) quite rare f1.0/70mm one (which I too have, new in box) but needs surgery to get it close enough to the sensor.

Hi Klaus,

I am, as you know, a fan of slightly less tame bokeh than the Meostigmats exhibit. I also have the 70mm f1.4 but rarely use it. One that I like is the Dallmeyer 51mm f1.5 Mk III, which satisfies my edgy taste.

OK, you like less tame, so how is this for you?

Great example of how the background accentuates the subject - doesn’t distract from it. Wonderful!

One of my fav lenses Andrea, very unique Petzval bokeh it has. With a bit patience, it
can be sourced, although prices for original ones have gone up quite a bit. I'll let you
know when I see one...

Just a note: the old Pathe Freres projection lenses were made by Hermagis, before they were bought by SOM.

Just came back from a shooting assignment in Kyrgyzstan, and on the last day had a couple of hours of free time in the capital Bishkek. I was able to wander around the parks with my Sony A7RII with an Angenieux AX Type 86 projection lens set to 95mm, and ran across a chess game on a park bench. I have a few other shots; this is the only one I've worked on so far, but I do like it. I'm also posting some earlier shots out and about, since I do like this lens even at longer distances.

Post by: Toby on September 12, 2018, 20:22:00
It turns out that my Angenieux AX Type 65 85-90mm lens with the insane swirly bokeh has been modified; the rear doublet was replaced with that from an unknown lens. I've managed to find an unmodified Type 65 (this one 90-95mm) and am posting my first tries with it. Still Petzval swirly, but not like the modified one, and extremely sharp in the center.

I admire your projection lens stamina! Very impressive thread Klaus :)  Wonderful and special images


A quick side question, do you consider to acquire an Z6 or Z7, seems to me you would benefit from having the actual rendering and Bokeh directly available in the viewfinder,?
Here I especially consider also that it's FX full frame and a really good viewfinder apparently.

I will just chime in to say that I use a FF Sony, and I find the critical focus and in-body stabilization features absolutely critical when using projection lenses. Most projection lenses do not achieve both best edge sharpness and best edge contrast at the same point, so critical focus lets me choose exactly where I want to be. And stabilization let’s me see what I am doing while in critical focus mode, when I am handheld, which is 99% of the time.

The Sony EVF is excellent, and with most lenses I can focus even without critical focus—much more easily than on the back screen of a DSLR in live view, even with magnification hood, and almost equal to an OVF. I would not go back to an OVF.

As to the Nikon specifically: the big advantage is the very shot flange distance—2 mm shorter than the Sony. However at this point no third party adapters are available for mounting vintage lenses. In any case I would stay away from the first iteration of any new camera. I will consider the Z8 and Z9 when they come out. And let’s see What Fuji and Panasonic offerings will be. At the moment I am 95% happy with Sony, a huge leap forward for me from DSLR.

Most welcome Toby! Haven't heard about that Wollensak lens, please show it and some results here! Wollensak used those dots, but I have no idea what they were for, I have those on some of my lenses, too especially the ones for their high speed movie camera, the FASTAX.

Hi Klaus,

A skilled mechanic has to take the rear lens part out, shorten and modify the barrel, then set the rear lens part in again, either glued or screwed.
I have a guy here in Germany who does that... (only works if lens is free of dents especially on rear part, only one of my four worked)

thanks Klaus. I use an old shooting technique from my early

Got two Pathe Freres Paris projection lenses (65mm + 85mm) through a friend,
guess they are from the 1920s..

Some shots with the 65mm mounted on my GH4, taken at last sunlight...

Such lenses and also projection lenses are usually used open, as they have no aperture.
Some people either perform some (delicate) surgery and add one (I have a few done by a very skilled mechanic),
or use an added aperture after the lens (enough back focal permitting), but that often leads to vignetting). A front
aperture is possible too, but for large lenses bit difficult to make and use.... But why bother, the idea is to USE
such a lens for its BG separation, requiring the full opening to achieve that.

As exactly Dr Klaus Schmitt noticed these lenses interesting on an open aperture. It is possible to put a diaphragm to or after a lens, but often we get vignetting. Putting a diaphragm is necessary between lenses, into a lens. Putting in Rodenstock is very difficult, he is fully filled by lenses (9 шт.) gaps between them are too small. A diaphragm is easily enough put in lenses collected on the chart of Petzval are 4 lenses in two groups.

Vladimir, these are delightful images of an attractive model.

It is interesting to see how these lenses behave when they are focussed beyound the short subject distances used to make the images we often see made with them (such as the dreamy smooth bokeh rich close up images often featured on this site).  However these lenses also show great potential for longer subject distances, e.g. the Rodenstock Heligon 100 мм f / 1,6 used in your posts (303, 296) below.

Excellent illustrations of the quality of the Rodenstock etc. optic. To elaborate on what Hugh says, after having abused these lenses by putting them way off their designed operational range to get super soft blurry pictures, it is refreshing to learn what we tend to forget, namely, they are high-quality performers. Provided they are allowed to work as they are intended, towards infinity focus that is.

Was looking for this VISIONAR f1.9 200mm monster of a projection lens to complete my VISIONAR collection for quite  a while...
and voilá today at a photo fair, I saw a just too well known lens silhouette on the next table, while chatting with a nice Olympus service guy ...
so I interrupted my chat, went over there, negotiated a bit, and came back to continue my chat with a big happy grin in my face...
as the price I got it for basically was a steal ;-)  ;-)  ;-)

How to make the Meopta Meostigmat f1.0/50mm work...

The lens barrel has to be shortened first see first pics 1+2 (while doing so, the rear lens group will need to be taken out, later re-inserted again). I then used Rafcamera adapter pieces to mount onto a chinese M65 helicoid (pic 3+4):

(http://forum.mflenses.com/userpix/201812/455_Meostigmat_50mm_mounting_c_1.jpg) (http://forum.mflenses.com/userpix/201812/big_455_Meostigmat_50mm_mounting_c_1.jpg)
[click for larger image]

On my Panasonic GH4 this then leaves quite some space, so it focuses quite a bit over infinity, which I adjust using the set-screws of the lens mounting adapter ring. Focusing range here is then infinity to some 150mm close-up  ;-)

I recommend using a clamp-on sunshade as there are no front threads.

Here is what I managed with a ROW Rathenow Busch System 120/80. It's actually a horrid petzval lens, in which one has to choose either sharpness with extreme haloing or decent contrast completely unsharp. It is 120mm, aperture should be f1.5 obviously but my camera seems to think it is around f1.3

Post by: Toby on December 16, 2018, 23:11:25
I got a lot of two General Scientific Superlumo 4.75 inch projection lenses. One had some separation in the back element (cemented) so I decided to experiment with using the rear cell of a Busch projection lens with the front of the GS. I find the results not altogether unpleasing, but certainly unconventional.

I have been following this thread with interest for a while, and thought it would be fun to contribute. I have a basic Leica slide projector sitting in my closet, with a Leica Colorplan 90/2.5 projector lens (which replaced the rather average Hector 85/2.8 lens). The following shots were taken along side my Tokina 90/2.5 macro, with the same focal length and max aperture I thought it would be interesting to see how they compare.

All pictures taken with my D600 from a tripod. The Colorplan was "mounted" via a set of K extension rings - the tubes simply allowed me to hold the projector lens by hand while keeping it reasonably well centered and blocking stray light. Focusing was achieved by moving the lens in and out to achieve a sharp image.

First up, the trunk of a tree aloe, covered with dead leaves which have remained attached to the tree. Tokina first, Colorplan next. The Colorplan has a slightly narrower field of field of view so the focal length may be closer to 95mm. The central sharpness is excellent, nearly as good as the Tokina, dropping off towards the edges of the frame. The Tokina is known as the "Bokina" as it has a reputation for good bokeh but I don't think it holds up at medium-far distances, the Colorplan has much smoother background rendition (none of the funky bokeh featured earlier in this thread)
Title: Re: Projection lenses
Post by: Roland Vink on December 31, 2018, 07:10:52
Next, a closeup of a Lavatera flower, nearly at 1:2 magnification. Again, the Tokina is first, the Colorplan is reversed for this shot. The Tokina, not surprisingly, is sharper with better contrast. The Colorplan has more of a "glow", but with a reasonable central core of sharpness.

I was cleaning out some junk in the barn and came across the skeleton of a movie projector, on which was a rather interesting Bell & Howell " 4" Incre-lite  F2.8,with the unusual feature that its thin end fits into my microscope adapter.  Wipe worst of grunge off, and out to chase bugs.  A quick preliminary result says it's hard to hold steady without a tripod, but it has a pretty nice look, I think.  It looks pretty business-like on the camera too.  Not quite as impressive as those new probe macros, but the working distance is pretty nice.  I may actually have to clean the glass!

p.s. the camera is a D7100, the adapter a hacked Konica, the plant a chive.  And I don't know how the date got turned on in the D3200.  Glitchy thing.

Esteemed Forum members,

This is my first post here, and I am starting by asking for some help.

I recently procured two lenses which are not exactly Projection lenses but produce similar results.  Given the very obvious experience and expertise so many of you have shown in so many images and posts, I'd like to ask for the following:

Does anyone have any experience adapting and/or having the specifications (esp. screw mount size/thread) for these two:

Rodenstock TV Heligon 64 f0.95

and

Wollensack Oscillo Raptar 75 f1.9

I'd like to ideally adapt them both to M42 so that I can exchange them between my medium format, full-frame, and cropped sensor cameras.  I do suspect that both lenses will likely fully cover only the cropped sensor, for sure.

Thank you very much in advance, and have a wonderful weekend!
Title: Re: Projection lenses
Post by: Toby on November 30, 2019, 22:35:51
I can counsel you on the Oscillo Raptar. My way of mounting was to wrap some PVC electrician's tape around the rear barrel of the lens, so that it fits snugly inside a M52 to M42 helicoid (25-55mm). This allows infinity to very close focus on a mirrorless camera. I also wrapped a bit more tape around the front barrel (it is slightly smaller diameter) so that I could use the lens reversed in the same helicoid. Reversing the lens exaggerates the bokeh. The Oscillo Raptar has a curved field, so it is not really useful as a general purpose lens, but it has nice bokeh. Stopping down to f2.8 increases contrast and reduces highlight glow, with still very characteristic bokeh.

If you are trying to adapt to a DSLR you will not be able to focus to infinity. Even holding the lens directly on the mount of my previous Nikon D800, maximum distance was about 20cm from the lens. Reversing the lens gave me slightly more distance. I believe that the flange distance of the lens is about 30mm. Below is an example with the lens normal,  the second with the lens reversed wide open, the third with lens reversed stopped down to f3.5.

The Raptar will most definitely cover FF. It may also almost cover MF, but the corners will be extremely soft.

Post by: Birna Rørslett on December 01, 2019, 12:03:55
The general approach to modifying the Heligons is getting suitable threads, for most lenses that means 52mm threads at least. Most of my Heligons allow a 52mm Cokin-type adapter or similar to be located at their rear end, pushing against a wider flange further down on the lens casing. Either fix the ring containing threads by epoxy glue, or small screws if possible. From this thread, preferably of the female variety, one can add extension tubes and then any kind of lens mount adapter at the very end. I'm fond of using the ancient K-ring sets for this purpose.

With the 100mm f/1.6 XR-Heligon, I also have the option of mounting it into a 65mm helicoid for use on my Z cameras. Mounted in this manner it easily reaches infinity.

Hi folks,
I just received a rather strange old projection lens, an Astro Nitor 105mm. From the look of it, it should be a standard Petzval, but the look is quite different from other Petzvals that I have. Here are some first shots from it, and looking forward to playing more with it in the next days. The lens is completely uncoated, and flares very easily, with low contrast at the best of times, so these shots have been adjusted for contrast, sharpened and optimized according to my eye.

The sharpening plugins that I use work on a certain radius, and that often coincides with the radius of details in the bokeh, so of course the bokeh is emphasized. If you look at the sharpening of the details in the face of the statue you will see the same kind of sharpening, which I find desirable. But the basic character of the bokeh is not really changed. Have a look at this, which is without any sharpening

I have the Colorplan lens shown on picture. I never got a projector for it so only use was for looking at film on light table which it was quite good at.
Do you think such a lens can be used for taking real pictures?
Which kind of adapters do you use?    .....it must be real homemade?

It has a deviation figure specified (+0.2mm in this case). I was told it was if you used multiple projectors for overlapping images then you could select lenses with same deviation. Lens has been on the shelf for many years.

It is an excellent lens and quite better than the normal Colorplan based on its MTF chart, also the color transmission is better.

Leitz stated in its brochure about it:

""Advanced optical computation methods led to the SUPER-COLORPLAN-P2, whose optical performance surpasses even that of the renowned COLORPLAN-P2, to the point that its imaging quality is comparable to that of the APO lenses for our LEICA M and LEICA R cameras. Its highly corrected optical system provides excellent resolving power, brilliant illumination, true color fidelity, uniformly high contrast rendition and unequalled sharpness across the entire image area.""



Title: Re: Projection lenses

Thank you for the information. I got the idea.
Can see my Leica projection lens is a "real lens" so should probably not just be put on a shelf. If the lens has "M-lens quality" it is a cheap way to get such quality. These lenses are not that expensive as I remember and maybe even cheaper today as most people does not use slides projectors. It is very rare I use it. But quite fun when it happens. 

I have a 6x6 slide projector. The latest Rolleivision 66. There is an adapter system so it can also take 24x36 cassettes.
I read somewhere that a 24x36 lens like the Leica could be used on the 66 using an adapter but I never looked for it as I used the AV-Apogon 120/2.8 which I got together with the projector. It requires a bit longer distance to the screen for 24x36 but it worked and the 120/2.8 seems to be a nice lens also for 24x36. How good it would be as a photographic lens I don't know. It is quite large in diameter.
But an interesting idea to use these lenses on a camera. 
Title: Re: Projection lenses
Post by: dickb on April 17, 2020, 21:35:40
Your Leica projection lens has a mount with a diameter of 52.2mm. A system as described by Klaus is very nice and convenient to use. But if you just want test it quickly another option is a set of cheap chinese manual extension rings. These come in (at least) two diameters, 60mm threads for Canon EF mount and 57mm threads for Sony E and eg Minolta MD - I think 57 for Nikon F as well, but I don't own any of those. The inner diameter of the 57mm tubes is a decent match to 52.5mm projection lenses, especially when you use a thin flocking paper inside the tube. This makes a surprisingly decent sliding focus tube. The helicoid mentioned by Klaus is more precise of course.

I have two Rollei 6x6 150/2.8 projection lenses, a Heidosmat and an S-Heidosmat. Its tubes are 74mm in diameter. This won't work with the 65mm adaptation from RAFCamera as it is too wide. My lenses however can be unscrewed from this tube, it has a 71mm thread. So for your Leica lens to work in your Rollei projector you need some sort of adapter from 52.2mm to 74mm. I don't know of any, but I'm sure such an adapter can be made.

I found the manual for the P66 dual and it seems there is a part no. for the 35mm lens conversion set.
Other places in the manual they talk about a "reducing tube".
Maybe conversion set is with 35mm condenser and everything and may be the reason for not trying to get it and be happy with the 120mm and 6x6 condenser system. If worked great with 24x35 also and the only projector I had which was 100% sharp from corner to corner. The Leica projectors I had......like P150, P300 or P600 IR had some small alignment problems.....if you looked very carefully. I never had a "tank version" like P2002. 

Do you know if the real 65mm conversion kit used to end up with M42 mount using the Leica lens...….the set screws to fix the lens for infinity focus…..does the set screws go deep into the metal tube of the lens?

Well, the 35mm condensor would be nice if you felt the need for more light when projecting 35mm slides. If not the reducing tube is the only part you need to use matching 35mm projection lenses. There are several tube diameters for 35mm projection lenses though, and the original reducing tube may reduce to a different diameter than you need for the Leitz lens. My 35mm Rollei lenses are in 42.5mm diameter, but they may have used different sizes as well.


Do you know if the real 65mm conversion kit used to end up with M42 mount using the Leica lens...….the set screws to fix the lens for infinity focus…..does the set screws go deep into the metal tube of the lens?

There isn't a fixed conversion kit for any specific lens, there are parts you mix and match to suit your lens and camera. I for one don't use the 65mm versions, but 58mm as I already had several parts for it. A kit would consist of a ring to fix the projection lens to a helicoid, the helicoid itself and an adapter between the helicoid and your camera of choice.

Most (but not all) rings for fixing the projection lens to a suitable thread have an internal metal strip, protecting the projection lens from the set screws and distributing the clamping force.

The total length of adapters and helicoid must be short enough that you can get infinity focus. Ideally you get the longest helicoid that will just allow you to do that. Short helicoids have a short focus range, longer ones are much more convenient.

I have the original Colorplan-P2, before I bought it I compared it with the Hector 85/2.8 lens which came with my projector. The Colorplan was already far superior - brighter and sharper - the Super-Colorplan must be impressive if it is even better.

So maybe I should not spend more time with this lens other than use it for viewing film on a light table which it is quite good at. Does a German made Super Colorplan exists?

Some time ago I had a couple of vintage Colorplans for the Prado 250 and 500. They were chromed versions and made by Leitz in Germany. Very nice lenses. All the Prado stuff took up too much space so it all went to a historical photo club so they could sell it and get some funding for the club. These Colorplans must have been version 1 and not the P2 I guess.

The tubes with flocking material I described in a previous post are essentially the same as the Samtfokus device, a sliding focus tube with a friction material that doubles as flocking. If you get the dimensions/tightness of the tube right it is surprisingly precise and comfortable to use.

That is not the conclusion you should draw from the Cavina comment. He shows that the 42.5mm diameter Colorplan that was made both in Germany and Portugal had a cheaper mechanical construction in the Portugal version. I don't see any difference in the optics between the two, apart from possibly a slightly higher susceptibility for flare for the Portugal version. Anyway, this doesn't concern your lens at all. Yours has slightly better optics and much better mechanical construction than either 42.5mm version. I used to have the 52.2mm made in Portugal Colorplan Pro that shares its mechanical construction with yours .

I agree, If one reads cavinas article he states that there is more shiny plastic and less matte baffling but he explains the rear  plastic ring with possibly allowing for heat expansion of the rear element-. Given the traditions of leitz quality control, I would be surprised if they would allow markedly substandard products even if penny pinching by modifying designs for cheaper production processes abroad at times were needed. Production outside of Wetzlar or Solms need not be automatically suspect. At least one projection Elmarit was made in Austria, that one looks very solid.Cheapness through plastic parts in  existing lens designs  obviously was not the case for the Canadian Midland works where dr Mandlers designs and the Apo-Telyt was conceived.
Title: Re: Projection lenses

Yes, my seems to be a 52.2 mm version. Most is metal but if I look at the rear element there is a ring around it which looks like plastic. Lens has never been in a projector and been exposed for heat so lens is probably ok still. The ring which holds the rear element is metal but screwed into a plastic ring?   .....sounds not good but looking at the video below the whole shell is plastic but lens does ok. Probably such a conversion I could try. I could not find any images of the "friction tube" solution.

The samtfocus is not a mere friction tube, but a specially made tube with internal helical grooves that will guide the velvet strips (samt in German) glued to the lens tube. There is presumably no need for a video since the tube sets were made to order by Heitchen and distributed in the same way as the special universal adaption - VNex set.

I had mine furnished with a special MFT mount in order to accomodate my very short-back focus Angenieux and Astro projection lenses.

Ok. I found info about the vnex here. Looks like good quality:
http://forum.mflenses.com/the-vnex-enlarger-lens-project-v2-0-t67487.html

All this and also the Samtfocus is via the German digiclub?
Or is there a link to "Heitchen" where he sell stuff?

It seems it is "Heitchen" himself in the link and also a mail address is provided at the end. So I guess he could be contacted for further information.

It has matching internal helical grooves? Fancy indeed, the original Leitz projection lens focus tubes only have a single protrusion point. I must have misremembered Henry's creations, I thought the VNex tubes were the helical ones and the Samtfokustubus aka SFT was just a draw tube with velvet lining.

Yes, my seems to be a 52.2 mm version. Most is metal but if I look at the rear element there is a ring around it which looks like plastic. Lens has never been in a projector and been exposed for heat so lens is probably ok still. The ring which holds the rear element is metal but screwed into a plastic ring?   .....sounds not good but looking at the video below the whole shell is plastic but lens does ok. Probably such a conversion I could try. I could not find any images of the "friction tube" solution.

https://www.youtube.com/watch?v=tSNFoAe9dko

This is similar to what Klaus and I were suggesting earlier. In the video the lens is fixed to the helicoid extension tube, so all the focussing is done by the tube's helicoid. One reason why this exact setup will probably not work for your lens is the inner diameter of this helicoid extension tube. Your lens is 52.2mm in diameter the entire length of the rear barrel. The lens in the video is a 42.5mm diameter lens with apparently a 52mm diameter portion close to the front. Your lens will probably not mount into the M52-M42 helicoid like the lens in the video, likely just on the front M52 thread. This is not the most stable configuration and you may not end up reaching infinity focus because the entire length of the helicoid is between the lens and the camera. So for you a larger diameter helicoid is more useful, like the 65mm one Klaus recommended or the 58mm I mentioned. In these cases you do need a ring connecting the 52.2 barrel to M65 or M58, like the ones from RAFCamera. Maybe a M58-M52 step down ring could work as well, though not quite as stable probably

I must admit that I may confuse the two systems since I have both, but the tube with internal grooves and MFT coupling on the other end  is certainly the one I used for the photo above.

Think I have got the idea. Different solutions like helicoid and "friction" for focusing. May get a helicoid next time I order adapters from China. I have a Z50 on the way so have already ordered some adapters.
This adaption below is a bit more complicated but interesting:

Title: Re: Projection lenses
Post by: dickb on April 23, 2020, 13:06:46
The adaptation in this video is interesting indeed, but perhaps unnecessarily complicated. He removes the 42.5mm outer barrel so the lens will fit into the M42 helicoid. Another option would be to use a wider, say M52 helicoid instead of the M42 one. No hacksawing required.
Title: Re: Projection lenses
Post by: MEPER on April 23, 2020, 13:39:27
Yes, but otherwise an elegant solution to work the M42 adapter a little so it fits the 42.5mm barrel and then mount the helicoid using screw mount. To secure a M52 helicoid you would use a "set screw" or friction solution via a ring that makes the 42.5 mm barrel thicker?

I like the pictures he shows at the beginning of the video using this lens.
Title: Re: Projection lenses
Post by: MEPER on April 23, 2020, 13:56:38
It was a 52 to 43 step down ring he uses to begin with......I just realized. There are many rings to be confused about…….

The overdose of separate elements can be intimidating, but you do get many options to get to your optimal setup, either for a single lens adaptation or for a system you can adapt many lenses to.

There are a few little things that can be frustrating when combining many rings and tubes:

- the internal diameter of rings and tubes can vary quite a bit. Some helicoids have fairly large flanges or baffles or internal constructions that restrict the internal diameter. Don't expect an M42 helicoid to have an 42mm inner diameter over its entire length.

- check the orientation of the threads in your setup. I like to use a 58mm reverse adapter to Sony E for my camera, so I need a female 58mm thread connected to my projection lens.

I know it is not portrait light - frontal makes faces boring, I was just playing with Henrys VNex - some time ago -
this lens imo is strong in handling any colour or tonality, see skin tones, it has a nice bokeh and it is energy saving  ;), you do not always need to write "shot wide open"

Here are a few from a rather rare Angenieux TV1 120mm f1.2 projection lens. This beast was designed for a prototype Philips TV projection system in the 1960s that never made it into production, so not many of these were made. Since the resolution for TV at the time was very low, and the CRTs not too bright, precedence was clearly given to speed over performance with this Petzval lens. It has a lot of highlight blooming when in focus, and when the contrast is highest, the image is not in focus, so it is a game of tradeoff between the two. Nevertheless, I have gotten a few interesting images out of it, and I think it would be perfect as a soft focus portrait lens

While rummaging in the barn the other day I came across a forgotten slide projector, with a 5 inch Wollensak lens. All its optics are at the outer end.  For other macro work I found a T mount with an extension tube whose threads are sloppy enough to screw into the mount and accept a Pentax threaded lens, and found that with the barrel shortened a little, I can slide the Wollensak on and get infinity focus.  The primitive sliding focus is a little sloppy and hard to get right,  and the lens is not killer-diller sharp, but it has an interesting look, I think.

It's 3.5.  Originally came, by the way, from a Revere projector with no magazines, and a different lens diameter from the Sawyer projectors I actually have the trays for, so no compunction about taking a hacksaw to the barrel.
Title: Re: Projection lenses
Post by: Matthew Currie on January 11, 2021, 06:52:34
Rummaging in the commodious barns I find another, this a Bell and Howell 5 inch 2.8, from an odd combination 8mm and filmstrip projector I stored away but, since I haven't used it in over 30 years I figure it's safe to steal the lens.  This one goes in another scrap mount from a dead zoom,  and with a tiny bit of trimming will go to infinity, but since the sun rarely shines here in January I can't test for interesting outdoor highlights.  Here, however, is how it goes as a macro.  Focused on a rail, with a little contrast and sharpening in post, this one isn't likely to displace the micro Nikkors any time soon, but it might work for portraits.

I'm not buying many lenses these days, but I did pick up a Kinon Superior I 5cm f1.8. Very interesting lens indeed. Unlike all the other shorter Kinons (5cm Superiors and 5cm Superior f1.6, and 65mm Kinon) this lens does not have swirly bokeh. Instead it has very strong bokeh. The lens covers about 80% of FF focused at infinity, about 90-odd percent at 1 meter, and covers the full frame at close distances. It is very sharp in the center of frame, albeit with some highlight halation, and though it is uncoated, is much less prone to flare working against the light and ghosting than most other projection lenses of the era that I have used. Here are some examples, post-processed, but not radically so. Some sharpening, contrast and clarity adjustments.
