It came mounted on an 58mm plate (does anybody know for which mount/camera this could be?)
It has a tiny screw mount, slightly smaller than C-Mount, so I guess M24 or M25.
The aperture is only adjustable from 4.5 to 11.
It's one of the smallest lenses for 35mm film (it least I guess it's for 35mm) I've ever seen.



It has some strange stains on the surface. First I thought it's fungus inside the lens, but now it looks like damage coatings to me.

The mount (m25? m24?)

Some other ~50mm lenses for comparision.
It's the smallest lens I have. The first is the Pantaplast, the second an Rodagon 50mm, the third a Helios 44-2 58mm and the fourth a CZJ Flektogon 50mm

(ISO1600, I guess wide open, handheld in front of the NEX)

Does anyone know more about this lens? Is it an enlarger lens or for use on bellows etc.?
How old is it? Except the stains I looks pretty new.

Sorry for pushing up this old thread.

A friend told me that this lens was used for microfilm reproduction and printing.
That would explain the good sharpness and that the aperture is only adjustable between f/4.5 and f/11.

Can anybody confirm that?

I have to make some more tests with this lens Smile

EDIT: I found that in Russian language: http://translate.google.de/translate?hl=de&sl=ru&tl=de&u=http%3A%2F%2Fclub.foto.ru%2Fforum%2F21%2F406307&anno=2
Could this be a microfilm enlarger?
It's the only trace of an identical lens I can find on the net. Seems to be pretty rare.

I saw a 75mm Pantaplast on ebay the other day.

I just assumed it was an enlarger lens.

Liesegang was a professional slide projector, enlarger and microfilm viewer maker, and still is a overhead projector and video beamer maker. As far as I can make out they never made a camera (not even a microfilm one), but they made large and medium format enlargers (which might have been fit with a lens for 35mm enlargements), and had a period around 1960 when they made small format enlargers (going by the interweb, with a fixed lens). And long after they quit enlargers they still made microfilm printers to print pages from a fiche onto a photographic paper hardcopy.

That Russian page shows another Pantaplast on a Liesegang Uni-Rax enlarger (http://translate.google.de/translate?hl=en&sl=ru&u=http://club.foto.ru/forum/21/406307) - so these seem to have been the companion lenses for their mid-range consumer 6x6 enlargers...
