Optical Block - LOMO OKS6-75-1, #820001

The lens was made at LOMO in 1982. It is last known modification of the 75mm OKS lens line. So, I believe that it should have great optical quality.

For sale is optical block. It has no focusing mount, so you'll have to adapt it to your system yourself.

Also, there is a diaphragm, but no control ring. You may operate aperture with a pin, but it is not very convenient. So, you'll want to add aperture ring as well. Not comples task, but it will take some time and money too.

This lens is worth to invest efforts into it. 16 diaphragm blades provide perfect bokeh. 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.
