Fotodiox Pro Lens Mount Adapter - M39/L39 Screw Mount SLR Lens to Sony Alpha E-Mount Mirrorless Camera Body

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 all Pro-series adapters, these adapters have been specially crafted to endure professional lenses. The leaf spring design in the adaptor holds the lens tight to the camera body ensuring there is no play between the camera and the lens. Its all metal design and polished surface is designed to guarantee smooth mounting and long lasting experiences. This adapter allows Leica M39 Lenses to fit on a Sony Alpha NEX E-Mount system camera body.

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. You can shoot with manual mode or aperture priority mode. Infinity focusing is guaranteed.
