Lenkinap 2.8/18mm lens RO71-1 - optical block

Quite rare version of Lenkinap (renamed to LOMO later) 18mm lens made in 1958 (#580929). Large front element, small rear element. f/2.8, T/3.2. Weight is 480 g.

Interesting feature is aperture scale on the rear end of the lens. It is marked both in f- and T-values. Works fine. Blades are clean and dry.

Excellent optical condition. There is just one tiny scratch on the front element (less than 1mm) that will not affect image quality.

The lens has no focusing mount, so you'll have to adapt it to your camera yourself.
