The Pentax 67 Lens to Leica S Camera Lens Mount Adapter from Metabones allows a Pentax 67 mount lens to be attached to Leica S cameras. Metabones adapters are quality made, using precision-machined brass with chromium plating on both the camera-body and the lens sides of the adapter in order to ensure smooth mounting, quality aesthetic, and durability. This adapter uses a matte-black finish to minimize internal reflection. Although the lens will fit physically, automatic diaphragm (AE metering), or other auto functions are not retained using this adapter. Both camera-side and lens-side of the adapter are made of brass, precision-machined and plated with chromium. Precise fit and solid connection - lens has no play, gap or wiggling when mounted on adapter and no adjustments are required to fit your lens. Designed to reach infinity focus while maintaining the correct registration distance required to maintain optical quality of CRC lenses or lenses with floating elements. The lens side of the adapter features a strong leaf-spring structure, strengthening the adapter-lens connection and ensuring tightness of the lens. Satin surface finish.
