Industar 69 lens for Chaika II camera.
So far I have only seen three Industar 69 lenses like this one.
This lens is longer than the classic Industar 69, in fact it is approximately 24-26 mm. long. It also has the following diaphragms: 16-11-8-5.6-4-2.8. The focus ranges from 1 to 3m. There are neither other distances nor is there the infinity indication.
I believe that this is really a prototype lens.
Might the optical scheme be similar to Tessar?
Lens n. 20815
Made in 1967 – 1972 ?
