Made from solid brass for a smooth and firmly focusing movement.

     All its component are CNC machined, collimated and tested in a Leica M8.

You can use 50mm and tele lenses as 85mm and 135mm, all will be rangefinder coupled with perfect focus even wide open. Wideangle lenses only fit on Leica M1 to M4 bodies with my special adapter, not rangefinder coupled.

     Re designed, spring loaded lens lock lever. Also is 6 bit coded.

         The Sonnar 50/1.5 and Nikon 50/1.4 are basically the same, but the distance of the optic elements to the focal plane are different, for that reason Contax lenses must be used on a Contax adapter and Nikon lenses on a Nikon adapter. The same apply to the tele lenses.

     Who offer a adapter where to use both, Contax and Nikon, not is being honest, or do not have technical knowledge about this theme and the adapter it will fail in the focus in one or both brand lenses. [ back ]
