LOMO 2/75mm lens OKS6-75-1 in Konvas/Kinor OCT-19 mount, #860154
This lens was made at LOMO in 1986 (#860154). f/2, T/2.2. The lens has OCT-19 mount and fits Konvas-2M, Kinor-35. Can be used with other cameras if you have corresponding adapter.
Cine optics gives soft image. 75mm focal length is one of the best choices for portrait photography. The lens covers full 35mm frame (24x36mm) easily (though it was purposed for 35mm cine cameras). Depth of field is shallow enough to separate an object from background clearly, that gives excellent impression and add cine-like feeling to a video shot with such lens. Combine all this factors, and you'll understand why so many people hunting for such lenses to adapt them for their DSLR's and camcorders.
Very good appearance.
Mechanical condition is fine. Both aperture and focus rings move smoothly.
Glass has some cleaning marks, some dust inside, and some tiny dots inside - looks like tiny oil drops, but may be damages of coating layer actually.
