LOMO 2.5/18mm lens OKS5-18-1 in Konvas/Kinor OCT-19 mount, #800016
Great wide angle lens. Seems to be last modification of the 18mm lenses made at LOMO. Serial number is 800016, so the lens was made in 1980.
Excellent mechanical condition - both focus and aperture rings rotate smoothly.
Glass condition is fine except of common problem for this model - crack in the next-to-rear element. It hides behind diaphragm blades from T/4, so the lens can be used almost without limitations. Crack shape allows to suppose that it will not grow.
Industry standard 32 pitch follow focus gear is installed.
Both caps are included.
