Near my house are selling a Zenit 100/1,5.

I never saw it before.

Cine? UV? Photo?

Anybody knows?

Thanks. Rino.

Could be from a night vision system, I saw such lens types. The Russians made quite a few of these types of lenses for that near infrared application. It would need to be tested out for visual photography since usually the coating is different. If you look through it to sky or a white sheet of paper, is the glass colorless or how does it look like? These lesnes are not color corrected so do show quite some CA (chromatic aberration) and usually the glass appears yellow (it is the IR transmissive coating) if you look through, blueish is the reflection of the coating. [I have similar lenses]

Hi Luis. Thank you.

The lens that I saw is older, I think. But for the same job. Sure.

Rino.
