HELIOS-44M-4 lens F2 58mm for M42 ZENIT PENTAX CANON NIKON

HELIOS-44M-4 is a lens with springblend aperture designed for Soviet SLR 35 mm Zenit cameras. The lens can be fitted on the M42 Pentax cameras. First HELIOS-44 lenses were borrowed from Carl Zeiss BIOTAR lenses and issued since end of 1950th years in M39, then in M42 screw mount, and had not very good glory because were with low contrast in common... But latest versions of HELIOS-44 lens became very sharp. This famous lens was manufactured in the USSR, and features outstanding sharpness, contrast and color rendition. I saw photos taken with similar lenses several times before and I appreciated excellent pictures quality. In the main, most all Soviet and Russian lenses are exceptionally good and this one is no exception! It can be used with a lot of digital Micro 4/3 cameras with simple and inxpensive adapter.
