LOMO OKS11-35-1 2/35mm lens, OCT-18 Konvas mount, #800439
The lens was made at famous LOMO factory in 1980 (#800439). This is very last modification of standard 35mm primes in the OKS series.
It is purposed for 35mm film movie cameras, but covers larger area. Back focus is quite short, so it will not work with reflex DSLR cameras. But it works fine with hybrid digital cameras.
The lens has so called OCT-18 mount for turret Konvas. You can use it with other cameras if you have corresponding adapter.
Very good appearance.
Mechanics is fine. Aperture ring has click stops. Quite much oil on blades.
Glass has some cleaning marks Looks like rear element has some fungus on edge.
