The lens was made at famous LOMO factory in 1985 (#850179).
It has so called OCT-18 mount to fit turret Konvas cameras (for 35mm film). But the lens covers larger area, including full still image 35mm frame (24x36mm). On the other hand, back focus is quite short, so it will not reach infinity focus on SLR cameras. But it will work fine on modern hybrid (non-reflex) digital cameras.
Very good condition. Mechanics work fine. Aperture ring has click stops. Glass has some cleaning marks and need some cleaning. One 'ear' on focusing ring is broken.
