LOMO (KMZ) zoom lens Meteor 5-1 F=17-69mm f/1.9, Krasnogorsk-2 mount, #798843
F=17-69mm, f/1.9. Made in 1979.
It has Krasnogorsk-2 mount. You can purchase MFT (Micro 4/3) mount for it.
Appearance and mechanical condition is fine. Glass is not so good. There are many cleaning marks and some haze on the rear element. Front element of zoom block has coating damage and fungus. Good lens for amateurs only, not for a pro.
The lens is for 16mm film camera, so it is recommended to use it on Black Magic Pocket Cinema Cameras to avoid vignetting, though it will vignette a bit even there at wide angles (F=17-20mm).
