Contax Carl Zeiss 45mm F/2 Converted Leica M Mount Lens

This is a unique Contax Carl Zeiss Planar 45mm f/2, originally designed for the Contax G system, that has been professionally converted to Leica M mount using an MS-Optics MS-45 rear assembly. The result is a rare and highly functional hybrid lens: the superb Zeiss 45mm Planar optics adapted for seamless use on Leica M-mount rangefinder cameras.

The Planar 45/2 is one of Zeiss’s most celebrated compact designs, known for its outstanding sharpness, micro-contrast, and neutral rendering. On a Leica M body, it offers a slightly wider-than-standard field of view, ideal for travel, street photography, and documentary work. The conversion maintains smooth focusing and full rangefinder coupling, making it as close as possible to a native M lens.

Condition: Excellent

This Contax Zeiss 45mm f/2 Planar conversion is in excellent condition. The glass is clean and clear, with no haze, fungus, or scratches. The focusing action is smooth and precise, aperture blades are snappy, and the conversion has been carried out cleanly with an MS-Optics MS-45 rear assembly. Cosmetics are excellent, showing only minimal handling wear.

A rare opportunity to own a Zeiss Planar 45/2 in Leica M mount, combining the optical performance of Contax glass with the usability of Leica rangefinder cameras.
