I have this nagging suspicion these will not be the last ones by the mighty 6 mm f/2.8 posted on NG ...

Erik has arranged for this lens to accompany us to Scotland. A true NG First !!

(http://media.techeblog.com/images/nikon-fisheye-lens.jpg)

The lens has 220 degrees field of view and thus can look behind itself.

We intend to, Bjørn already put together an optical relay to retain the circular image even though the D810 'crop' to 16:9
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Bjørn Rørslett on March 12, 2016, 20:41:00
According to Erik, we need a relay system to reduce the image circle to make it fit inside the narrower video frame. I have made one solution that apparently works and will try out at least another before we arrive in Scotland.

Meanwhile, any video footage will be slightly cropped top and bottom of the image circle projected by the fisheye.

Yes, Erik is of course correct.
These guys had the same problem - https://youtu.be/Aw0i_I2TaAM
The stills they recorded show the full image circle but the video is cropped.
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Bjørn Rørslett on March 12, 2016, 21:23:28
I'm aiming for 0.7X reduction of focal length. That should make the image circle fit inside the frame for video.
Title: Re: Nikkor 6mm 2.8 Ai
Post by: RonVol on March 12, 2016, 21:30:08
Something like this perhaps?  :P

A quote from the guy who put this together - "We had to build a heck of a reflex lens assembly [note the other Nikon lenses in the stack] to shrink the 8-perf image circle from the lens to the 3-perf negative area of the RED."

I used relays for my 10 mm f/5.6 OP-Fisheye on the D1 way back in 2000 ... The combination shown is OK as it provides 0.7X, but there is no field lens or fine-tuning of focus. I might use the Repro-Nikkor 85/1 and a reversed 1.4X TC instead. Adding a helicoid for focusing is required in my opinion. Otherwise too much strain is put on the respective lenses.

This is the 10 mm f/5.6 OP Fisheye Nikkor with a 0.6X relay lens on a D2X.  I aim for slightly more for the 6 mm on an FX camera.

That's an amazing piece of glass !

I would be scared to scratch the front lens. I wonder how is the protection. Something like the Nikkor 14mm f/2.8 (leather lid) ?
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Erik Lund on March 12, 2016, 22:14:22
Yes a relay similar to the one on the RED camera, I stole the idea from Bjørn when he did the DX relay as he mentions ;)

There are two ways of mounting the lens, a 'standard' foot build into the base of the lens but also three 1/42 UNC sockets at the rear of the lens housing for vertical shooting,straight up.

For the standard shooting approach I have almost all the pieces; A carbon fiber Gitzo Series 5 with the lateral arm and a Burzynski ball head to lock it down for stills, I will have to look into If we need a fluid video head for the video or we just keep it simple and use the movements of the tripod, the 220 degree field of view put some restrictions on the possibilities,,,

The vertical shooting will be based on a stand-alone special build rig with a 6mm aluminum base-plate and three ø12mm aluminum rods connected to the lens via the three 1/4" sockets, it will have feet/spikes to sit low on the ground.

The vertical rig will have a ø85mm Gitzo ring so it also locks firmly onto the tripod. To be able to operate the camera and see the rear screen the base-plate will have a ø70mm hole to see through inside the ring/tripod.

It comes with a huge leather/metal clip on hood  with a soft pouch touching the front element inside, a unique design to Nikkors - Sadly there is no original flight case for this lens so I'm custom fitting a Peli-Storm Case for the lens to transport it in.

Francis, the 6mm/f2.8 and 8mm/f2.8 came with the conical screw-in metal covers.  These lenses have female threads around the front element for the covers.

Seems to be more pictures of the 6 mm f/2.8 than taken with it. We have to rectify that situation on the Scotland trip. My guess is that Erik will want to try out his new support inventions well in advance of the upcoming NG event.

I have seen the mighty 6/2.8 three times before; in Tokyo, London, and Copenhagen, but this will be the first opportunity actually to shoot with it.

In this case, not that many lens samples to collect. Roland Vink says only around 1000 units ever were made.

However, come to think of it, I own several Nikkors made in much smaller numbers than that ... But the 6 mm has to be extremely good to make me interested in owning one.

Thanks for the video link and the panorama-image - Very good with inspiration! Time lapse will work without the relay so a full circle is retained but on the other side as the image Klaus posted; Cropping works as well, and the lens does take the TC-201 tele-converter according to Nikon -12mm,,, although I have newer seen a photo from the 6mm with TC :) I have it so of course will try it out, should be good for panorama-images.

Thanks, Klaus, for the note.  The owner uses the fish with a film camera, so the portrait should be taken many years ago?  Apparently he is still doing the pano work, but I'm not sure if he is still using the 6mm fish...

In this case, not that many lens samples to collect. Roland Vink says only around 1000 units ever were made.
It may be much less than that. In the pre-Ai series, official figures suggest 29 units with serial numbers 628001 - 628029. I have records of 7 lenses from 628003 - 628024 so that seems about right.

The AI series starts where the pre-AI series finishes, starting at 628030. I have seen only 4 lenses with serial numbers 628035, 628042 which match well with the start number. The next number jumps to 628147 from a Nikon brochure (number not very clear). Then a big jump to 628556 sent to me by a collector.

The AIS series has a new serial number block starting at 629001. The earliest I have seen is 629004 on ebay in 2011. Then a big jump to 629400, 629410, 629415, 629417 and 629435. Of these three were sent by message with no picture so I can't be 100% sure there were no typing mistakes.

If serial numbers for the AI and AIS versions are continuous, I would expect to have seen many more by now. Maybe the missing lenses were bought by government/military/industry and never survived? Or they were never made in the first place with big gaps in the series, in which case production may be as low as 100.

What's the serial number of the the one at the NG event? if anyone knows of any other lenses which could help to fill out my data, that would be great.  :)

I have seen one 6mm 1:2.8 in person. It was no 628007 on display at the Nikon store in Paris back in 2004. At the time I was corresponding with a French Nikon user/collector called Bruno Najac who showed me and my then Fiance around Paris. We had a great time, but we sadly lost touch with him(still married to my now wife!)

Thanks Erik!
There is a 6mm for sale on ebay right now for $55K. Serial no 628035, an early AI model that I have seen before. That seems to be the case with these lenses, the same ones keep turning up over again, rare to see a new example...

Thanks, so no new numbers for my database.
I'll update my site to reflect the gaps in the numbers I've seen, I think the current listing grossly overstates actual production numbers.

I look forwards to seeing results from this lens at your NG meeting. I'd love to try an astro-shot - point directly up at night sky with milky way above, and landscape all around ... biggest problem is keeping dew off it ... maybe one of you guys will get the chance to do something like that? :)

Post by: Roland Vink on March 15, 2016, 21:32:25
I refreshed my lens serial no page so it more accurately reflects the serial numbers I have seen so far.

However, I still have a large gap between the early AI set (628030, 628035, 628042) and no.628147. If this series is not continuous I may still be overstating the quantity by over 100 units. And then there is no.628556 ...

These lenses were only made to order, so would have been produced in very small batches. I wonder if the numbering for the AI series goes like this:
628BXX where B = batch no, XX = sequence no.

Therefore no.628147 is the 47th 6mm lens made, but from batch 1, not the original batch 0. Lens no.628556 is the 56th lens from batch 5 ?? This would be a unique numbering system for Nikon but it does explain the strange distribution of numbers...

Post by: Erik Lund on March 22, 2016, 14:41:23
The vertical support is for shooting straight up, think a shot of the complete night sky and surrounding skyline - The 6mm has three extra 1/4" threads for this to avoid having the lens and camera supported only by the lens foot or planted on the camera display,,,

The vertical support will have three or four spikes to set it into the ground firmly, these come with rubber protectors as well is done on a floor for instance.

Second use is for mounting on a tripod again for shooting straight up but with view of the cameras rear display.

Third use is for  shooting with relay lenses and the needed extension tubes attached for shooting un-cropped video, there the plate acts as an extra support for the lenses and camera, I have made an extra set of extension-rods for this.

I will upload some image when I'm further with the manufacturing ;) Will be much easier to see than read the words,,, ;)

On a side note here is a concept shot of what I will try and use it for at work, I'll have our entire sales organisation in all of the 'windows' and ground level here in our Copenhagen headquarters ;)

It's two shots with 10.5mm merged,,,

Post by: Hugh_3170 on March 22, 2016, 15:00:58
Thanks Eric - I suspected that it might have been a tool makers lathe.  My lathe has an arrangement whereby a series of fixed speeds can be selected by changing V-belts on a pair of multi grooved pulleys.  OK for general turning, but not helpful for the low speeds needed for safe thread cutting, which must be done manually on my machine.

When I get rich and famous I hope to convert it over to one with an inverter driven motor that will give me fully adjustable speeds like the one you are using.  :)

Ron thanks for that image again! Really helpful for the details ;)

I should have done a more detailed sketch - but I have gotten a little sloppy over the years  ::)

I looked a little more at the image of the Vertical base and have noted a few things;

It doesn't appear to be a Nikon product,,, look and feel,,,

It appears to have four very thick rods, so it must have a ring behind the lens converting it into four rods from thee sockets, must have been for made for something else. Do you know if it is?
Nikon would never do that, IMHO much better with a single rod above the pentaprism - out of the way like the lens is designed for.

I will also do four feet, looks stable, and mine will be adjustable and spiked as mentioned, so no need to tuck the strap under the leg ;)

Yes - I already have a similar level for the base.

Something like this perhaps?  :P

A quote from the guy who put this together - "We had to build a heck of a reflex lens assembly [note the other Nikon lenses in the stack] to shrink the 8-perf image circle from the lens to the 3-perf negative area of the RED."

http://img.gawkerassets.com/img/17kmpym252yivjpg/original.jpg

I used relays for my 10 mm f/5.6 OP-Fisheye on the D1 way back in 2000 ... The combination shown is OK as it provides 0.7X, but there is no field lens or fine-tuning of focus. I might use the Repro-Nikkor 85/1 and a reversed 1.4X TC instead. Adding a helicoid for focusing is required in my opinion. Otherwise too much strain is put on the respective lenses.

Apparently the RED guy Ron found might have borrowed (or stolen!) the idea from Bjørn.  I just found this page from Bjørn's classic website.  See the Nikkor lenses combined as relay lens look identical (58mm Noct and 35/2.0):

Post by: Erik Lund on March 22, 2016, 22:48:47
Yes ;) I know Bjørn did the relay many years ago that's why I asked him to revise it but for the Big Eye - 6mm

I believe your right that he was inspired by that! Looks like it by his choice of lenses, I believe it was a 35mm 1.4 though,,,

This is the 1:1 Sectional view of the Fisheye Nikkor 6mm 2.8 that I use for the construction of the Vertical base.

I thought Bjørn used a 35mm f/1.4,,, ;) never mind it will be different since it's on a D810 16:9 not a 10mm on DX,,,

On another side note here is the off center Gitzo series 5 with Burzynski, the arm can be extended if needed with a monopod if needed for balance.

Yeah, that's one reason for you and Bjørns getting along well.  :D

I'm sure you are already aware, but I would doubt if the top plate of Gitzo Systematic is held to the vertical-mount hub firmly enough to hold the heavy rig you are preparing for.  A safety plate like the one sold at NatureScapes would be necessary.

I agree with you, the 4-post-mount isn't Nikon and must have some kind of backing plate/adapter as you suggest.

Adjustable height, like on a theodolite or optical level, is a very good idea.

Yes thank you for the warning Akira! - I am aware of this 'urban myth' ;)

As a mechanical engineer I feel quite calm with my design, as there will be zero stress on the ring in vertical position when mounted ;)

The only way anyone would have a problem with the Gitzo 'ring' design is if someone fail to tighten the clamp tight enough and walk around with the tripod over their shoulder with a long lens attached,,, then the wobble could lead to the ring working itself out of the clamp.

It is a ø70mm x 10mm long connection, there is no chance this will come apart unless the bolt breaks - Therefore I will reconsider if I should make such a 'safety-ring' since it's better to be safe than sorry!

Ron I will remember to wear a suit and tie  ;D
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Erik Lund on March 23, 2016, 09:18:48
BTW There is a much easier fix than the 'safety ring'

It is to drill one or two holes and cut threads in the collar and through the ring.

Actually the sketches are helpful to an onlooker such as myself for they show quite nicely the challenges that a 220 degree field of view pose for the photographer and how they will be dealt with in this instance.

Nice work Erik and an excellent preparation. 

I just hope that the weather and light will be kind to all of  the Killin group and that in due course we get to see this rare lens performing to its fullest.

I already have a screw like this in my Burzynski Ball Head adapter ring - Series 3-4 to Series 5 - so I don't loose the ring,,,

Erik, if you have a drilling machine, it should be easy to make it safer that way.

I don't think it is urban myth.  By Gitzo design, the bolt tighten the ring below the lower edge of the plate.  So, the more you tighten the bolt, the more the upper part of the ring will be open.  As a result, the ring is hold at the lower edge of the plate.

I replaced the central hub of my Gitzo Series 3 Systematic with the alternative hub made by Markins (TH-300).  So, the problem is gone forever.

Sorry for the deviation.  Let's go back to the original topic!  :)
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Erik Lund on March 23, 2016, 16:50:15
Yes this is true for the Series 3/4 - of course dependent on the depth of the plate this could be an issue,,, But this is not the case for a Series 5 where the bolt is located at the edge, not below, and when you tighten you can actually measure the collar getting smaller in diameter 0.2mm - closing at the top, not opening!

Title: Re: Nikkor 6mm 2.8 Ai
Post by: Bjørn Rørslett on March 24, 2016, 01:09:27
That might not be necessary. In the relay department, we can do a coarse focusing beforehand, then use the lens' own focusing ring for the actual shooting.

Post by: Erik Lund on March 26, 2016, 11:03:10
As I have all the parts, just not machined here is a mock up of the support ring for the tripod placed at 10cm from the camera and the RRS plate will go through the base-plate, when machined ;)

Lens relay will slide inside the ring and camera is supported by the base-plate,,,

A long rail could support the whole system from camera to Fisheye, not sure this is needed,,, But it would make it extra rigid.

Thanks!

I just realized when doing the mock up that I don't need the Base-Plate in Video set-up - If the relay is only 20cm long, and the D810 has the battery pack and RRS L-Plate mounted then I just need a long rail to hold the lens and camera into position.

After setting up infinity focus on the relay, the length can be locked down as Bjørn says. Since focusing will be IF inside the 6mm Fisheye,,,

So here is a snap of the situation this morning, was a late night up working on the mock up for the relay system Bjørn is nicely putting together fro the video 16:9 format Fish-eye project ;)

The keen observer will see an old Micro-Nikkor 105mm f/4 Ais, similar body size as the 6mm and with the hood it as same length when at minimum focus and the dedicated hood so together with the sectional view print enough to get close to getting the support right,,,

I could read between the lines Bjørn's concern for the well being of the relay lenses - and I concur! Fortunately with the added grip with EN-EL18a for plenty of power for the video the height of the camera incl the RRS plate is close to the height of the 6mm so very little shimming is needed, so we will have a very stable set-up both regarding handleling but also to set up and shoot, the clamps will just be loosened for initial focus of the relay, then locked down for shooting,,,

Also to be seen now is the TC-201, which is the dedicated tele-converter for the Big eye, 12mm Fisheye,,,  ;D Sounds fun to me and this old TC has several times surpriced me for close-up work where it has often done much better than using extension rings,,, food for thought for Michael's stacks perhaps  ;)

Erik, your mechanical engineer training really shines through here. Top notch workmanship.

The relay system for the video use with the 6 mm will comprise 35/1.4 & 50/1.2. The Repro-Nikkor relay approach does work, but the projected image circle is smaller. I have tested the relay with my 8 mm f/2.8 and it seems to work just fine.

Here is the Vertical base mounted under the 6mm - I had to trim down one of the rods since the D810 Camera body is a bit larger than the old film cameras

Instead of using the high and heavy Burzynski ball head I can use a Really Rught Stuff 'Monopod head' it has much less intrusion into the frame and a lot less weight ;)

The lens foot of the 6mm only has one single screw mount  ::) and the threads start so deep that only one single turn of thread has a hold of the lens foot  :o Completely a mystery why anyone would think that was a great idea,,,,

I have cut out room in the RRS plate for a much longer screw with counter sunk head also I have mounted an anti twist-block on the RRS plate to avoid any risk of the plate working loose or rotating.

Post by: Bjørn Rørslett on April 24, 2016, 15:01:06
Sometimes the engineers at the Mothership think in mysterious if not downright inscrutable ways. This fisheye exemplifies this with regard to the mounting arrangement, as clearly demonstrated by Erik. A similar case exists for the first versions of the mighty 360-1200 mm f/11 Zoom-Nikkor. The lens is very heavy and the slanted tripod foot is for once very sturdy. However, this apparent clever design is marred by the tripod foot that only has a single 1/4" screw hole and not a very deep one either, plus the base platform for mounting is set off from the major part of the foot so as to make a minimal contact area. What kind of engineering thought can explain such a silly arrangement? I had to redo the foot and the mounting arrangement completely.   

Pleased to learn you have done the Nikon engineers one better so we can enjoy the 6/2.8 to its fullest extent in the near future. Really looking forward to what the lens can do for "ordinary" as well as not-so-ordinary photography.

Im having some issues insuring this beast,,, well let's see if it doesn't work out.

It actually handles quite well on a monopod using live view, the 110 deg 220/2 deg can be dialed in on the RRS monopod head and you 'just' need to keep your toes behind the monopod ;)

Here its of course no issue as the D200 [IR] is a DX crop camera but just to show;  No hot spot in IR, and an quite acceptable DX cropping - I need a FX camera with IR filter,,, Andrea you have a D600,,,

Erik, how did you attach the anti-twist block onto the RRS plate?  The epoxy shouldn't be strong enough, and I don't see any screw...
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Erik Lund on April 26, 2016, 09:31:24
The thin tape is hiding the two screws  ;)

The RRS plates comes with M3 threaded holes for their anti twist blocks and end stops, I just made a block out of stainless steel and drilled the counter sunk holes to match for two M3 screws at 45 degrees to match the cut out in the lens foot.

The cut out in the lens foot is made for when the lens laying on the side resting on a flat surface without a camera attached - strange IMHO

Jakov I can hardly wait to go and shoot this Big eye with you all ;)

It's completely surreal to shoot with it because when you have the camera and lens in the normal shooting position your view is completely blocked - all you see is the rear of the lens and when you look through the view finder you see a tiny world in front of you without having any feel for how close you are to anything,,,
So I think I will try and use the Zacuto viewfinder in live view,,,

Did you end up buying the fisheye lens, or did you rent it for the NG workshop?
It will be fun seeing the lens in action and I'm curious what footage you will come up with (using the relay lens mentioned earlier).
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Erik Lund on April 26, 2016, 10:36:06
I have rented the lens for some jobs here in Copenhagen this week and for our Scotland workshop - then I guess I have used it plenty for my type of photography  ;)

There are so many other wonderful lenses I would buy before the 6mm - I'm not a lens collector  8)

I'm not sure we will manage to shoot a lot of video - also Bjørn has to cut down on bits and pieces he will bring so not sure he will prioritise to bring the relay,,,

Shooting 360 degree 220 degree field of view video is,,, to put it mildly super strange - you will have your shadow in the shot, tripod and everything if you don't take extreme care,,,,

So shooting it with the 16-9 crop is actually a huge relief,,,

Oh, I think I misunderstood then.
I thought the relay was made in order increase magnification in order to fit the full circle of the fisheye image into the movie frame.
Maybe we can assemble a relay on-site by combining lenses and extension tubes from various people (only volunteers of course).
I haven't decided what I will bring along, but if you need a specific lens that neither of you manage to bring along I can maybe take that into consideration.

No you didn't misunderstand.

The idea of a relay in this case is for having a circular Fisheye image in 16:9,,,

Thanks for volunteering for the parts! ;) A couple of parts are quite unique, short focus mount so Bjørn should bring that, other vice I need a 35mm 1.4 and a 50mm 1.2 I believe,,,  I'll ask Bjørn

Thanks Chris but the 55mm is too long and is it 35mm 1.4 Ais ? as we need the best possible coatings and lens,,,
Then it's a 50mm 1.2 Ais - my guess would be that Jan Ann will bring his sample ;)
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Bjørn Rørslett on April 26, 2016, 12:47:44
We need the following Nikkors for the relay: 50/1.2 AIS and 35/1.4 AIS. I'll plan on having the 35/1.4 with me any way. If JA brings his 50/1.2 the remaining parts (spacers, focusing helicoid, adapters) are easy to fit into the overfilled photo bag unless it bursts at the seams ... :D

The image circle of the 6 mm fisheye is too large for the video 16:9 crop. Thus the idea of the relay is to reduce the focal length and hence the projected image by a factor of 0.7X.

Are you going to shoot video with a Nikon FX DSLR?  I guess a focus reducer like the Metabones on a mirrorless camera would be an easier and simpler solution...

The problem is that the circle will still be too big to fit inside the movie frame. You need to project the small image onto a big sensor, not onto a small sensor, otherwise the problem persists.

EDIT: It may be that you can make full frame videos on one of those cameras, so that would be an option.
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Bjørn Rørslett on April 26, 2016, 16:39:19
I tried the relay setup with my 8 mm f/2.8 and D600 in video mode and the reduced image circle fits inside the video frame lines. So my hunch is the 6/2.8 will behave in a similar manner as their projected image circles should be approx. equal in size.

Using a Metabones focal reducer on a smaller sensor camera such as m43 makes little sense as the image circle still will be outside the frame. A bigger sensor in conjunction with 0.7X reducer is the solution for superfisheye video showing the entire 220 degrees  image without top/bottom being cut off.

Erik,

That first, of the two images, is just stunning!  I am learning a lot about fish eye lenses and how to use them. 

How does that image/lens hold up when displayed near 100% because the web image is really remarkable.

This entire post is so interestingly informative.

Thanks.

Thanks for all the nice comments ;) The first one is also the chosen to go into print ;)

The lens is really impressive but very demanding, focus must be spot on and as mentioned it shines at f/5.6 for such an 'old' lens design I'm completely satisfied with the performance - I have not done any A-B comparison there really is no equal,,, But I would say the performance is similar to the 8mm f/2.8 Ais or other high end lenses, it' better than the wide  lenses like 15mm f/3.5 more like a 18mm or the 16mm full frame Fisheyes.

the image sharpness falls off at the far edge at distant subjects, but not up close,,,

Here from the focus target about 1.25m  center of the frame at 100% on D810 ISO 800 - some PP but no noise reduction,,,

And here from the edge of the car shot, at minimum focus distance 0.25m f/8 ISO 450 D810 - Outstanding comes to mind,,,

I was invited by Svend-Erik from the shop Photografica to come and shoot the lens one more time for the fun of it, we had a nice lunch upstairs and I scouted around the store with a coffee and shot a couple of images - It's been quite fun to shoot the big eye, seems it's sold,,, not to me sadly ;)

Title: Re: Nikkor 6mm 2.8 Ai
Post by: Roland Vink on May 22, 2016, 22:10:05
Yes the extra angle of view really makes a difference.

Eric, what will you do with the rig you built to support this lens? Will you offer it to the buyer of the lens, hopefully they can continue to make good use of it, or will you keep it in case you are able to rent another copy?
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Erik Lund on May 22, 2016, 22:27:47
220 degrees 360 degrees makes for a huge difference indeed,,, That's why I build the vertical base ;)

I have offered to sell the vertical base to come along with the 6mm, if he doesn't buy it I'll re-build it to fit the 10.5mm AF-D to be able to do two shot stitches of approximately 200 degrees for 360 degree circular images similar to the 6mm but filling the D810 frame quite a bit more, I have all ready started the thread some time ago,,,
And if he buys it I will do a similar but smaller rig, no need for the same heft since the 10.5mm is tiny!

It can actually just rest on the Zacuto finder frame and rotate on that

Erik and The Lens

thanks a lot Erik, that I personally could see the use of this masterpiece by someone who mastered it.
My look onto these, mostly outstanding pictures now is different, than if I only had seen them on a screen.
My understanding of the search for the proper use of a lens went to a new level. I am happy that I was allowed
to "participate" in this exciting experience.

BTW, I am wondering what is this noticeable effect at the bottom letf corner (half past seven).

A flare ?
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Erik Lund on May 24, 2016, 10:55:53
Thanks!

It's flare from the sun, it's there opposite the sun in more or less all shots outside when the sun is on the sky, often there is also a large orange and smaller blue flare blob and several blue and purple flares, there should be some visible in the building on the right of the sun.

When shooting directly, cantered into the sun this orange flare is circular and in midway in the image. Amazing lens ;)

Been shooting with both my 8/2.8 fish and many other extreme wide angles (e.g., the 13mm) and one big advantage of the SLR & DSLR is the ability to observe flare as I'm composing.  If not too critical to the composition of the shot I purposely put the flare in an area of the image that I can easily clone out with PhotoShop.  If the flare winds up in a complex, busy part of the shot that flare is much harder to edit out.

Thank you all for the comments!

I have on purpose kept most of the flares to show what and how the lens actually shoots - I have on several occasions noted that somehow that particular flare spot actually hit the shadow of the lens on the ground right in front of me... you will see some of these in the Scotland thread...

I have enjoyed shooting the 8mm 2.8 and 14mm in various versions an the tiny 12mm Voigtlander they all flare a lot,,, the worst lens was the 14-24mm AFS - very unpredictable in this regard.

The 6mm 2.8 gives the most amazing images straight up - So only real chance of getting rid of flare was to move around a lot,,,

Seeing you expertly work with the lens in Scotland was the highlight of the trip for me. I still look for 6mm shots when I am walking around, I expect you do also  :)

The seller is OK though, I bought several lenses from them, but of course not in the same price league as the 6/2.8 is positioned..

Except for it basically being about the very same lens sample (owned by Photografica of Copenhagen, Denmark), it really adds nothing except for the oohs and aahs of people never using such a lens.

Post by: Bjørn Rørslett on July 02, 2016, 14:23:09
A side note: I spent quite some time trying to optimise the output from the relay system by combining various optical items and spacers. The final configuration worked very well for HD video at least, producing crisp and clear footage.

Inserting a field lens into the relay might have improved rendition further because the relay optics could be stopped down more, but vignetting is always an issue in these setups. A general notice is that the only stopping down should occur at the front lens, in this case the 6 mm f/2.8 Fisheye, not on any of the relay optics. I mention this because it is a counter-intuitive principle to what most people would select, but the recommendation has a most reliable source (Brian Caldwell).
Title: Re: Nikkor 6mm 2.8 Ai
Post by: Erik Lund on July 02, 2016, 16:05:25
A huge thanks to Bjørn for assembling the relay and to Jan Ann for lending me his 50mm

The peak image quality was at f/5.6
By a huge margin!

The whole set up of the relay was very tricky, the tolerances to reach peak performance was super tight. I used quite some time as well fine tuning the optimal length of the k-rings to enable a margin to 'focus' the length of the relay.

In conjunction with the first round of discussions on the might 6/2.8, the f/1.4 came up. It probably is intended for a much smaller format then its big brother though. Seems there is some kind of relay system/beamsplitter attached to it.

I was about to ask the same question about the bow tie - hope you do have one of these, Erik?

Bow tie? I thought it was a bat.  ;)
