Title: [Theme] Df (D750)+ Rodenstock Heligon 100mm f/1.6
Post by: Jakov Minić on September 11, 2015, 11:48:46
Thanks to the 'unsharp' thread I started looking at some last year's photos that I took and that are anything but sharp :)
I've stumbled upon a folder containing photos from Keukenhof, a place with many flowers.
Anyway I wanted to show off this photo.

Once again I would like to thank Erik Lund for introducing me to the Heligon, and for being kind enough to let go of his copy. Not that there we much negotiations over it. I came to CPH, I tried the lens, and it simply had to be mine! Veni, vidi, vici!
It's a tricky lens to use since there is no aperture ring (you shoot constantly at f/1.6), and there is no focusing ring (you are always stuck at the same distance from your subject). Considering these facts it's very challenging, fun, and rewarding whenever you get a shot right. There is practically no depth of field...

Great photo.

Completely agree with Jakov. ;)  Was lucky to find on Ebay a for Nikon adapted version of the Rodenstock Heligon 100mm   f/1.6  and adore the lens.

It makes some difference if you use it with extension-tubes or not.

Two shots with the D200  The Kalanchoë-Calandiva and some leaves of a Rose...

I have mounted one of my Heligons in a Nikkor 18-70 barrel (it was fun removing all the innards  :D ). Plenty of epoxy was needed.
It's certainly a fun lens to use when I'm in the right mood.

Nice project, Bjørn J. The barrel apparently fits perfectly.

I like in particular the Clematis shot.

By the way, you will have little trouble fitting the appropriate CPU chip as the mount is pre-drilled for it :D - shall I make you one?

No way. The aperture is removed, and the zoom and focus on the barrel are properly epoxy'd and forever stuck in that position  :D

Order one on eBay and send it with some money to Erik aka Dr Lens for modding :)

Jakov bought Erik's copy with a Nikon mount and Erik made mine exactly to spec with an exchangeable mount for multi camera use so he knows all the ins and outs of this lens. Plus it would be a nice topic for the modding section.

Not sure about the current production. They are (were) mainly used in X-ray machines and image intensifier setups.

Do note there are many of these 100 mm lenses with different specifications, and also very different optical capabilities used on a modern camera.

The specification to look for is 100 mm f/1.6 Rodenstock Heligon. There are various models of these as well, but I think all should behave quite similar.

Keep away from the f/1.5 model as it is much less useful due to its design.

A final point, that applies to all Heligons, is that they are very heavy because of the large high-refractive glass elements inside.

In the case of the examples shown here I am not sure if it is more the genius of the photographers than the
construction of the lens. Anyway. I love these shots so keep them coming.

Heavy, yes! My 100mm/1,6 mounted in the 18-70mm shell, weighs 804 grams. Some of that weight is epoxy, though  ;D

You can also do it yourself, with a bit of patience and a Dremel. The Rodenstock does not have any means to mount it - the camera end is a smooth tube 43mm in diameter.

Just order a T-ring to Nikon adapter (or any other camera) over Ebay ( or http://www.cncsupplyinc.com (http://www.cncsupplyinc.com/)). This has a 42mm female thread that you will need to grind down by >0.5mm all round so that it fits firmly over the end of the lens. Then glue the threaded end of the adapter over the lens using a strong metal to metal adhesive such as JB Weld.

I bought a cheap 62mm rubber lens hood and affixed it to the front of the lens (no thread) using black electricians tape for outdoor use and to protect the exposed front element. The lens is front heavy, so you might want to support it - I use a 65mm Burzynski lens collar and foot that I already had for another lens.

These Heligons are really simple to modify to accept Nikon F mount. See the attached picture of my 100/1.6 Heligon.

Add 52 mm thread by securing a Cokin filter holder adapter with 52 mm male threads. Depending on the actual lens, you can epoxy it in place, or drill a few screws to keep it in position.

Thereafter, just add K-rings (K4, K5) to give the adequate working distance and magnification, and end with the K2 to provide the "F" bayonet. Not including the curing time for the epoxy, a 3 minutes job at most ...

One can of course use a focusing helicoid instead of the K-ring(s), but remember most such units will not have sufficient clearance inside to accept the thick rear end of the lens.

Bjørn R, that looks like a flexible solution. I have the K-rings, but I can't find that particular Cokin filter holder adapter on ebay. This one doesn't look like the one you have:

Probably you should seek for the Cokin A series instead?

The P adapter will work, but adds unnecessary girth and thereby handling awkwardness to the modified lens. One could of course Dremel down the Cokin, but as shown below, not much would be gained in overall slimness as long as the K-rings are deployed.

Below is the 100/1.6 in the "minimum" configuration with K4, K5, and K2 added. This combination of extension provides a bayonet just clearing the rear element so is about the shortest you can have with an "F" mount camera. For m43 or similar, you need something that will accommodate the  naked rear end within it to allow focusing farther away, perhaps even to infinity if the contraption is short enough.

(this is from the first stage with the 100/1.6 so the CPU hasn't been added yet. It will fit nicely inside the K2, though)

This reminds me of my having to return the last CV90 on the shelf, due to excessive amounts of chromatic aberration. It hurts, because the lens is now discontinued, and the tactile feeling was that of solid quality; which of course proved itself not to be true. I miss it, though.

Neither the 90/3.5 nor the 180/ APO Lanthars are equally "APO" like the 125/2.5 CV. But that does not entail they are poor performers, very far from so. One just has to allow for the ever so slight CA on occasion. Easy to remove with the modern tools at our disposal.

Besides, Datura species are annuals or short-lived perennial, herbaceous, and often are dichotomously branched. This looks like some kind of shrub or tree.

Datura leaves are often hairy and smell, like the entire plant, on the unpleasant side. A kind of sickly sweet odor.

Thanks for clarifying John!

True Bjørn - it is a small tree. The flowers has a lemon-sweet odor. A bit too much for me..

I got curious and read this in an article (quote from Davesgarden.com):
"If your neighbour has wonderful Brugmansias in his garden, no problem; but if he also grows Datura do not get into arguments with him, you never know what he might do..."

Sorry, John, I only just perceived your answer. Thank you very much. Digging into the Wikipedia-Article on the Canna https://en.wikipedia.org/wiki/Canna_%28plant%29 I found:

Post by: Bjørn Rørslett on October 06, 2015, 10:25:05
There is no doubt the Rodenstock 100 mm f/1.6 is "photogenic". The combination of relatively long focal length and fast speed leads to clearly defined planes of focused vs. out-of-focus detail, that make the image 'pop'. Still the lens has to be used deliberately to gain these results, they aren't immediately available just attaching the lens to a camera and poking it around in a random fashion. Also adding to its success is, in my opinion, the lack of an adjustable aperture, and the need to add or remove extension to change its magnification of detail (or if you prefer, change its focused distance).

Many of these amiable features are available in other industrial lenses as well. However, the 100/1.6 has the advantage of a quite long register (distance from rear element to film plane) as far as this kind of lens goes. Thus, one is not forced into using it only for extreme close-ups, a fact that furthers adds to its versatility.

If the rear lens group of these superfast lenses is removed, you get much longer working distance. I hardly need add that the level of optical aberrations skyrockets concomitantly, but hey, you don't shoot with these lenses to get *ultra sharp* pictures do you?

I tried this trick briefly with my Oude Delft Rayxar 65 mm f/0.75 lens. Autumn colours came through beautifully and of course, such a lens is just about bokeh. In fact, so much bokeh there hardly is room for anything else.

Shot this morning with the Df literally on my door step. This kind of lens visually "enlarges" any space to the extreme so you hardly need to move around to find new scenes :D

Funny you should say that, as we speak a Heligon f/1.5 is on my desk in pieces. Because the f/1.5 version of this lens has even shorter working distance than the f/1.6 version, I never used it. I decided to see if I could rearrange the lens elements to see about getting infinity focus. I pulled all of them out and started putting them back in with different combinations until something made focus. Right now it looks like I have three elements on the desk and 3 in the lens. Not sure how useful it will be as I haven't used it much yet, but I got it to focus to infinity.

Interesting observation and experiment, Charlie. Thanks for the heads-up. I'd like to echo the warning regarding the 100/1.5 Heligon: it is way inferior to the f/1.6 in terms of practical usability due to the very short back focus distance (that is, unless you pull the lens apart into separate components :D ). Thus, stick to the 100/1.6.

I expect most of the optical power resides in the (heavy) front group(s) and that the rear group(s) are added to correct aberrations downstream. Seen as a whole our tests on "massacred" lenses confirm this.

A slide projector lens probably will perform equally well (sic) and might be worth looking into. Heligons have seen a substantial price hike due to the rekindled interest in them, so always beneficial to have a cheap alternative for experimentation.

Interesting, I'll try some more element combinations. According to my notes its a 7 element lens and I was able to achieve infinity by removing the rear element (1), removing the front three elements (5, 6, & 7), and leaving elements 2, 3, & 4 in place.  Adding element #5 also worked for infinity but the lens needed to be moved further from the camera to do so. Secretly I was hoping to create a lens that mimic'd some vintage lenses I had seen with nice aberrational qualities, wishful thinking.

I do have a box of projector lenses laying around, perhaps those will be dissected next.

The process of (partially) reversing tonality curve(s), used to be called "solarisation" in the film days and then shrouded in by myths and lots of experimentation, is become so very simple in the age of digital photography.

Still, cliché or not, it is the outcome that counts not what path has been followed to get there. So kudos to Jakov.

Jakov: is this the same photo shown earlier, but re-processed to fit a bleak Thursday? Perhaps we should start a new thread exhibiting "The image of the Day", but constrain ourselves to the same image in up to 7 different versions? That might be entertaining.

I doubt that it's the same photo, probably not even the same flower, but I do see your point in posting an image processed in 7 different ways for each day of the week. We get something similar with the RAW EDIT Challenge, don't we?

On topic but off topic, how is everyone mounting their Rodenstocks? Care to share pictures of the modified lenses?

I'm grinding out a very thin Nikon F to M42 adapter that I was planning to epoxy to the lens, trying to keep as long a focus distance as possible. Before applying the epoxy I thought I see what others are doing.

The 100 mm f/1.6 is very simple to adapt to F-mount. Add 52 mm threads to it for example by using a Cokin filter adapter that has the suitable threads.  Then, add K-rings to act as spacers, and put a K-2 to the other K-rings to provide the camera mount. In the picture below, K-2, K-4, and K-5 have been used. Additional K-rings will allow the lens to focus closer.

How do you mount the filter adapter on the lens tube?
And, is the K-2 safe to use unaltered on a modern body?

Post by: Bjørn Rørslett on November 04, 2015, 13:31:31
Usually the 52 mm thread supplier (Cokin or similar) can be seated against any convenient flange along the rear lens casing. Most of these lenses appears to have a step-ladder like profile, so the threads will find a final home somewhere. Exactly where is immaterial as you just add more spacers if necessary.  Fix permanently into position by small screws or judicious application of epoxy glue. Just ensure the threads stay clear of any glue residue and all is well.

Photo below should illustrate the basic concept (sorry - old photo and I just realised it isn't sharp at all, but should show what you need to know anyway).

I have used K-2 on all models of modern Nikons without encountering any problem, so that is what I would describe as 'safe mounting' in my book.

Charlie you images turned out stunning, especially the third one of the series!
Bjørn, simply has a tendency to leave me silent when he shows his photos as is the case again!

Since I am terrible in archiving and have huge difficulties in retrieving images, I have to rely on the scientific approach of stumbling on to them.
Here is the first image I took with the Heligon when I visited Erik in Copenhagen. Now it all came back to me. I was taking Erik to see Primus perform. Then he showed me the Heligon, I mounted it and took this snapshot. It wasn't clear at the time that I would fall in love. That came soon afterwards when we went out for a stroll and I realised the bokeh potential :)

The 100/1.6 has a sibling looking very similar but slightly faster (f/1.5). It is little known even to the Heligon fans probably because - unlike the f/1.6 model - it has too short back focal distance ('register') to be useful with DSLRs.

I'm flying down to Copenhagen today to team up with Erik for a nerd-y weekend. One major project is adapting the 100/1.5 to various mirror-less systems for which it very likely will shine. Informal tests indicate it has even smoother bokeh than the already butter-like rendition of the 100/1.6.

I think anyone interested in this particular Heligon should take notice and acquire one right now, before it sees a price hike ... :D

A quick search on eBay using "Rodenstock Heligon" brought up 100+ lenses. Not all are desirable for photographic purposes though, so one has to be selective. The famous one of course is the 50/0.75 of which there are two models, designated TV- and XR-Heligon, respectively. An image intensifier setup probably used TV + XR in combination, but for our wicked 'need for speed' assignments, either will do.

I didn't notice any f/1.6 among the 100 mm class, just the f/1.5. Erik and I will see what can be done in terms of adaptation of that one during this weekend.

Alex, here is a link to a 100mm Heligon on ebay. Although it does not state that it is an f/1.6 lens in the listing or on the lens itself, I was under the impression that it is the f/1.6 model. I'm not sure if that is that same variant that others here are using but it is identical to the lens I own and can confirm it will focus as far as approximately 30 inches when held to a Nikon F mount flange, I used it to make the images posted in post #180 & #181.

Bjørn, I look forward to your findings. One of the f/1.5 variants is the same lens I dissected in search of infinity focus. I'm curious, have you used the Heligon 42mm f/.75 lenses? I own one, and a Kowa version, but haven't used them in years. If I remember correctly they only focus about 3 inches from the front element.

Thanks for your reply Bjorn! I was specifically googling RODENSTOCK HELIGON  100/1.6; the eBay did not showed up in my search. I am not big fan of the eBay but if nowhere else avail I will check it out.

Alex: the 'laser' lens is not the correct one you are searching for.

Do note there is a 95 mm f/1.4 that also shares much of the properties of the 100/1.6, including the ability to focus further away the the 'near-sighted' 100/1.5

Charles: I used the 42/0.75 to some extent many years ago, but tired of it as you are locked into the near range all the time.

Rodenstock makes a series of 'laser' lenses that are designed for a single narrow-band spectral range. At least some of these create wild chromatic aberrations.

One should not be fooled by the external appearance only as many models have lens barrels designated for interfacing with some specialised hardware. So different shapes exist for the very same optic.

Went today to Jan-Anne's place to borrow his Heligon (and collect my NPK 24/2.8).
Unfortunately we couldn't get of all the adapters, so I went home with a non-functional NPK lens and without a Heligon.
I guess I'll have to wait until our Scotland trip.
Bad end of a nice weekend. :(

Things got so intense that Chris told me I had two weeks to leave his town because Amsterdam was no longer big enough for the two of us....

He stopped flexing his big guns when I started to cry a little but wouldn't leave before I started packing.

Post by: Jakov Minić on December 11, 2015, 15:25:14
All of the photos posted in this thread are hand held.
There is no focusing ring on the Heligon so I use my neck muscles for focusing :)
The extension ring used is a PN-11. Focusing distance is about 30 cm.

It's amazing how limitations improve ones photography...
Even if you don't have a limited lens like a Heligon, just try it out, fixed focal length, fixed aperture (any 1.4 or 1.8 lens would do), and a fixed focus distance.
Then you really start to think and pre-visualize the image before looking through the viewfinder :)

Thanks. I use a focusing rail (mostly with the PN-11) for indoor shots with the Heligon. Outdoors, its hand held - with its attendant low rates of keepers.

The description says "no aperture specified on barrel" and the measurements provided suit the 95/1.4  I have in my possession. However, it must be put into a very large and heavy casing you don't have any need for. Unless you want to save a trip to the local gym.

Another pic with this ''alleged Heligon'' with unknow aperture, unknow focal distance... ;D

What I am pretty sure, is that is not faster than f/1, otherwise this lens would be much larger and certainly heavier.

Only few weeks to wait now until I get some clues from experts... ;)

This is probably the best image I took in 2016 thus far. At least according to my taste.

Perhaps we can open up a 2016 portfolio of all NG comrades? We can post only one image that we believe is the best photo we made in 2016. We would need to detail how you made it and what gear you used and what you wanted to achieve with it. A true portfolio like story.
At the end of 2016 we can all enjoy going through our NG 2016 portfolio.

On eBay there are all kinds of Heligons, but not the 100/1.6

Take a look at the auction at the link below, that is one version to keep an eye out for though you should be able to find it for less than the asking price if you practice patience. It does not state f/1.6 on the lens anywhere, in fact I don't recall seeing a picture of a 100mm heligon that does say f/1.6 on the lens though from what I understand some members here do have such markings, where others including myself have this version. Nonetheless this version has up to 3 foot working distance or so with dreamy qualities. It is the 100mm f/1.5 lens to avoid because it has a very short working distance of only a few inches, unless you're willing to make some 'adjustments' to the lens.

Looks like the f/1.5 ... If the focus is < 0.3m away, the assumption is strengthened

By the way, apparently the Spanish Customs have learnt a thing or two from their Norwegian counterparts and held your Heligon 95 mm f/1.4 for a good while now. Hopefully it'll arrive into your hands in a near future.

  It did arrive friday to my hands. It focuses about 1 meter when held close to the mount and I have a picture to show it. I couldn´t wait so I tried -and I was surprised it is possible- to shoot just holding it with my hand.

 It promises a lot of fun.

  It did arrive friday to my hands. It focuses about 1 meter when held close to the mount and I have a picture to show it. I couldn´t wait so I tried -and I was surprised it is possible- to shoot just holding it with my hand.

 It promises a lot of fun.

Glad to hear it!

Yes, you can shoot with it un-mounted from the camera and in fact I do that all the time with Heligon's and other odd lenses for testing. I have one of those M42 - Nikon F mount adapters with the correction lens in it that I mount to the camera so the sensor doesn't fill up with dust, then an M42 to to 52mm adapter screwed into that with K-extension rings to block stray light. I have a couple different Heligon's I have yet to mount that I use in this way.

I look forward to seeing how you use your new lens.

Hmm...the bellows/mount part of a lensbaby may work nicely in this case...

The only difference is I have used the D750 and not the Df.

Very striking photos!  In the second one I like the intensity of the colors, and their separation from one another.  But I like the first even better - it captures the essence of the flowers with what seems like a few strokes of a painter's brush.

Cheers - John

John and Jack, thank you so much for your kind words.
It is the Heligon that got me into "painting photography" where sharpness and resolution, among other things, have no play.
I am really glad that you like the images that the Heligon produces.

This is not an easy lens to use.

And the reverse.

There is a lot of discovery to be done.

Love the shot of the weed, Jack.

Yes, Like Jakov says it's an a-typical lens which needs a different approach.  ;)   A great lens but with the lowest rate of keepers ever ! 

The point is also, evaluation on the camera-screen is not always efficient, so in post-processing things get more clear, usually.
Title: Re: [Theme] Df + Rodenstock Heligon 100mm f/1.6
Post by: Bjørn Rørslett on May 11, 2017, 21:05:15
The parallel-Universe metaphor is apt. With this Heligon, and in fact with all similar lenses, one really needs to re-think what one wants to do with the camera and lens.

No funny business when it comes to my favourite tulip of all, the Toyota Tulip.
I solemnly declare that Akira did not cross my thoughts, when I found out the name of this beautiful flower :)

I wonder where it came from?  No wonder if I didn't come across your thought, Jakov, because I haven't been aware of the tulip with such name!

Beautiful image nevertheless.

Lest we forget, the Rodenstock behaves quite differently on the Z system cameras. Infinity focus is a breeze.

Adapting the Rodenstock 100/1.6 to the Z system is very simple. I just added a 65-65mm helicoid (17-31mm extension) with a Z mount on the rear end and a 52mm thread in front, since my Rodenstock already had a 52mm thread adapter fitted. Alternatively, I could have used the rear stock threads on the Rodenstock which I believe are 2" (48mm).

It looks simple.

But I made the most fatal error possible.  I glued the mount on the wrong side of the helicoid.    Nothing is possible any more.  The glue is too strong to correct the error.  And it is not possible now to connect the lens, to the moving part of the helicoid...

 I gave up...

Tried heating in an oven at say 200C? Most epoxy glues break at high temperatures.

Murphy's Law applies when the number of options >1.

As a last resort, I might find one of my spare Z-mount is no longer needed in Norway, but would serve better say in Netherlands :)

Sorry about your mishap, John.  Incidentally, I didn't realize that such a strong glue exists (special epoxy?).  I may want to glue a cold shoe on top of my SIGMA fp with that glue...

Thanks Akira.  It was extra strong 3 seconds epoxy. That glue also works great for other things and is stronger than the original 'bond'.       When will you have the SIGMA FP back?

Just tried the 200 C  method in the oven and it worked    ;D 

Can start from scratch now

Post by: Birna Rørslett on January 10, 2022, 10:17:38
Interestingly the epoxy glue should be hardened in the oven at 130-140C for about 30-60 minutes. Any higher temperature eventually will break the bond.

Looking forward to seeing your Rodenstockery contributions, John :)

Thank you, John, for the details.  I guess it would take at least two weeks until my fp comes back.  If the camera is in a "resalable" condition, I may take back the idea...

Thank you.  Still working on it ;) 

I ordered extra glue to cement a ring inside the adapter to connect the Rodenstock lens. Also the adapter-ring from 65mm to 52mm, to connect the lens to the adapter

To illustrate the 100/1.6 Rodenstock also works on FX cameras, here is a night snapshot with the lens on the Z6. The timber pile was entirely lit by moonlight so having a fast lens and ISO 3200 allowed me to capture the scene. The corners weren't that bad as this is not infinity focus, however I might have trimmed the frame ever so slightly. As said above, using the Z fc alleviates any worries about frame coverage or poor corner quality.

Love that shot, Birna.

As my Rodenstock has a 52mm mount thread, I ordered a special 52-65mm ring adapter to make a solid construction with the Helicoid.  The 65mm rings are hard to find, by the way.
