Fotodiox Pro Lens Mount Adapter with Focusing Barrel, for Mamiya RB67 lens to Pentax K-Mount (PK) DSLR Cameras

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 Fotodiox lens mount adapter is made with high standard precision. It’s all metal design and polished surface is designed to guarantee smooth mounting and long lasting experiences. As all Pro series adapters, these adapters have been specially crafted to endure professional lenses. No "play" between lens and camera. Aperture Priority and/or Manual Mode is required while adapter attached. Built-in Focusing Helicoid allows focus with any Mamiya RZ67 lens, super smooth and precise focusing barrel.
