The MIR-5H MC 100mm f2.8 portrait lens is a vintage manual focus lens made in the 1980s in the USSR. It is compatible with Nikon F mount cameras and has a maximum aperture of f/2.8. The lens is made of metal and has a sharp optical quality. Russian metal construction. It is a wide-angle lens with a focal length of 100mm. The lens is compatible with a 52mm front filter. This is unused, it was from my oddities collection, always had the idea I might use it someday. Comes as shown with protective bubble. Bubble has small crack, probably from age.
