I recently received some stranges lenses.
I know where it comes from : Leningrad (GOMZ), made in 1950. But I have no idea what is the purpose of those things. It looks like giant microscope lens.
One a is monocle with 2 lenses in front. Two others have complex optical design (5 or 6 elements inside). I tested the two big (the monocle does not form image), they give pretty good results, like a normal lens (but they are slow lenses naturely). The x20 almost cover FF (vigneting on A7), the x50 cover like a 8mm cine lens.
Anyone have idea about the use of those lenses?
I have talked with several friends about it. The main idea is that it is naturely technical lenses. Maybe gauge projection lens.
Here are some photos (before the cleaning, sorry)
