LOMO OKS1-35-1 2/35mm lens, OCT-18 Konvas mount, #661610
The lens was made at famous LOMO factory in 1966 (#661610).
It is purposed for 35mm film movie cameras, but covers bit 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 on other cameras is you have corresponding adapter.
Used condition. Mechanics is fine. Glass is clean and clear.
