Komura's compact slower wide — the 35mm f/3.5 in Leica Thread Mount.
The Komura 35mm f/3.5 in Leica Thread Mount is a vintage Japanese wide-angle made by Sankyo Kohki under the Komura name. It is a slower, compact moderate wide produced for L39 screw-mount bodies, part of the range of third-party rangefinder lenses the company offered.
It is a manual-focus rangefinder-coupled lens with a 35mm focal length and a maximum aperture of f/3.5. The moderate aperture keeps the barrel small and the optics simple, and it couples to the rangefinder for focusing on screw-mount and adapted bodies with 35mm frame lines or an accessory finder for composition.
The 35mm view is a versatile reportage and street focal length, and at f/3.5 the lens is well suited to daylight, travel and documentary shooting. It renders evenly and sharpens across the frame when stopped down to the middle apertures.
As a vintage third-party lens, used copies should be inspected for haze, fungus, cleaning marks, coating wear and separation, along with 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.
