I recently got a small lens turret with 4 Zeiss Jena DDR lenses. Three of those were Tessar lenses with fixed aperture (37.5/3.5, 50/2.8 and 70/3.5), the forth one is unlabeled but definitely isn't a Tessar. From a quick look I would say that it probably is a significantly more complex design with 7 or 8 lenses. I wasn't able to define its focal length exactly, but after a quick comparison and a measurement I suspect that it's a 25 mm lens with a max aperture of f/2.8 or f/3.5.
Do you know the what kind of device this piece of equipment was used in? It was sold as part of an enlarger, but so far I wasn't able to find it.
Here's an image:
I'm really curious what device it is from and also what kind of lens the shortest focal length one actually is, so any information is highly appreciated! _________________ ---

No mount. Just a rotating disk with a hole for the currently used lens. So the whole thing seems to be a kind of lensboard for the enlarger or whatever device it was used in.

Hi, I don't exactly know which device had this turret before, but similar lenses were used for microfilm documentation. Tessar 37,5 mm can be found in the reading device of the Documator. I have two other Tessars (prototypes) from the same series 95/4.5 and 100/5.6 with 25 mm Tubus. They fit very well into the Minolta MC Microscope adapter and can be used with the bellows.

The lenses pop up on ebay all the time, three of them are tessars - 2.8/35, 2.8/50 amd 3.5/75 if memory serves me correctly. Plain barrels, no iris
The fourth is more interesting as it is a retrofocus type 28mm, a lens Zeiss never sold for photographic use. Not sure of the design, I think it is 8 elements and is the same as the 2.8/28 Visiogon seen in other industrial/scientific uses. _________________ I don't care who designed it, who made it or what country it comes from - I just enjoy using it! |

Thanks - you're not far off actually... see below!

Indeed... but it's not much use if there's no proper mount I guess.

Thank you so much - that's it! They are from one of the "Dokumator Lesegerät (reading device) DL2". Here's an older listing: https://archiwum.allegro.pl/oferta/czytnik-mikrofilmow-mikrofisz-carl-zeiss-i7403600685.html
The lenses are the same as on your spec sheet, only difference being the Tessar 50 mm which is f/2.8 in my case. The fourth lens might very well be the Visiogon 28/2.8.

Many thanks - yeah that describes the group of lenses I have, just some slight differences in focal length/max aperture. As seen above the fourth lens (highly likely it's the Visiogon as you suggested) is a 7 element design according to the document posted above. _________________ ---

You're right - I found an old thread where you mentioned you having the f/2.8 version. Have you ever tried it? It's said to be working on APS-C. After comparing mine to some samples online, I suspect that it is the later f/2 version. _________________ ---

That looks like a really nice setup by the way and well done images! Have you ever presented it here or do you have some samples elsewhere? _________________ ---

Thanks! Some recent uncropped FF samples from a similar setup handheld are given below. Zeiss Jena Tessar 95/4.5 with parts of Minolta Microscope Adapter on Minolta Compact Bellows. The fotos are taken with 45 MP camera, slight PP (auto levels + sharp) and resize. Different scales are due to the different bellows extensions. I'm not a macro shooter in general. Actually the lens shows very thin DOF and good sharpness in the focus area. I'm looking for the shorter adapter to try it for my normal shootings, e.g. portraits or landscapes.

Looks great - thanks for showing! My setup is similar, but with a different bellows. Being used to the versatility of bellows extension I'm regularly forgetting about the fact that lenses have MFD... _________________ ---
