Tanar's mid-speed normal — the 1956 50mm f/2 in Leica Thread Mount.
The Tanar 50mm f/2 in Leica Thread Mount dates to 1956, made by Tanaka Kogaku for its screw-mount rangefinder cameras. It is a vintage Japanese normal from a smaller mid-1950s maker, offered as a moderate-speed standard alongside the faster Tanar fifties for L39 bodies.
It is a manual-focus rangefinder-coupled lens with a 50mm focal length and a maximum aperture of f/2. As a period normal it uses a compact optical design and couples to the rangefinder for accurate focusing on screw-mount and adapted bodies.
At 50mm the lens gives a natural standard perspective for portraits, street and general shooting, and f/2 allows moderate low-light use and background separation. Moderate-speed normals of this type tend to sharpen cleanly across the frame when stopped down.
As a vintage lens from a small maker, used copies are relatively scarce and should be inspected for haze, fungus, cleaning marks, coating wear and separation, plus focus feel and aperture oil. Confirm rangefinder coupling and infinity focus. It adapts to Leica M with an LTM-to-M ring and to mirrorless cameras via an adapter.
