KMZ (Krasnogorsk) PLANT VERSION, 1984 STANDARD FOCUS HELIOS-44M-4 LENS FOR M42 ZENIT PENTAX PRAKTICA CAMERAS ... or for a lot of other SLR with 42mm lens mount... and more SLR's DSLR's & MTF's via well-spread lens adapters! ABOUT ITEM'S ORIGIN (You can SKIP it!) 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 SLR & MFT cameras with simple and inexpensive adapters. ITEM'S CONDITION: EXCELLENT+ The glass is very clean, with no any fungus, separations or scratches, but very minor cleaning marks sometimes can be found. Aperture "jumps" correctly, aperture barrel is smooth. Focusing is smooth. Cosmetically the lens looks fine, just examine item's photos, please. All functions are available.
