Fotodiox Mount Adapter for Leica M39 Lens to Mamiya 645 Camera

If you have a SLR or DSLR camera and other maker/mount lenses, the FotodioX Mount Adapters allow you to use your lenses on the film/digital camera body. Sharing lenses has some distinct advantages. Certain prime lens just can't be replaced and you save the cost of purchase on new lenses. Fotodiox offers a range of adapter from large format to smaller format digital adapters. Adapting larger format lens to smaller format sensors (i.e.: large format to medium format, medium format to 35mm, 35mm to micro 4/3) provides excellent edge-to-edge sharpness. The smaller image field helps minimize the effects of lens distortion and aberration by using the 'sweet spot' or center of the larger lens image circle. This is one of the Fotodiox Pro-Series lens mount adapters made with precision and pristine award standard. As with all Pro-Series adapters, the Leica Visoflex M39 Lens to Mamiya 645 Mount Adaptor has been specially crafted to endure the repeated mounting and un-mounting of professional lenses. With unique styling, the lens mount adapter maintains/enhances professional appearance. This lens mount adapter allows Leica Visoflex M39 lenses to fit on Mamiya 645 MF or AFD Pro camera bodies (will not work on the E series). Although the lens will fit physically, automatic diaphragm, auto-focusing or any other functions will not operate correctly while using this adapter. In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body. Infinity focusing is guaranteed.
