This was made at Lenkinap (renamed to LOMO later) in 1960 (#600691).
The lens is purposed for 35mm film movie cameras like Konvas, Kinor, Arri etc. Covered frame size is 16x22mm. Actual coverage is bit larger, but not enough to cover still image 35mm frame (24x36mm) - there are dark corners. Also, back focus is quite short, so it will NOT work with reflex cameras like Canon or Zenit. But should be fine for hybrid (mirrorless) cameras.
The lens has so called OCT-18 mount (for turret Konvas cameras), but you may adapt it to other camera.
Mount diameter: 47 mm Length: 56 mm Weight: 135 g
Mechanical condition is fine. Aperture control ring works well (T/2.8-16, no clicks). Focus ring is smooth (1m - infinity scale).
Optical condition is good. There are some cleaning marks. Rear element has numerous cleaning marks and some wear of coating.
