Metabones Leica S to Mamiya 645

The Metabones Mamiya 645 to Leica S Adapter allows Mamiya 645 lenses to be mounted on Leica S cameras. Constructed from precision-machined brass with chromium plating, it ensures a secure, precise fit with infinity focus. A matte-black finish minimizes internal reflections for optimal image quality.

Adapt your Mamiya 645 lenses to Leica S-mount cameras with the Metabones Lens Mount Adapter. Built with precision-machined brass and chromium plating on both the lens and camera sides, this adapter provides a smooth, durable connection while maintaining a high-quality aesthetic. The matte-black interior reduces internal reflections to maintain optical clarity and contrast.

Designed for infinity focus, the adapter preserves the correct registration distance for lenses with floating elements or close-range corrections (CRC). The lens-side features a strong leaf-spring structure to enhance the connection and ensure tightness, eliminating play or wobble. While the adapter supports full mechanical operation, electronic functions such as autofocus or automatic aperture (AE metering) are not retained.
