KO-140M 1,8/140 USSR Soviet Projector Projection Lens.
This lens can be modified and then can be used on new digital SLR or mirrorless cameras. I can't modify it, i just sell the lens as-is.
Please look at pictures carefully. What you see is exactly what you will have.
There are many small dots/scratches on glasses + some haze/fungus and dusts, which is pretty common for vintage lenses.
AS IS, no returns, no refunds, please.
Any questions - please ask. I'll be happy to help.
