Take full advantage of your Mamiya 645 medium format lenses with the Fotodiox Vizelex RhinoCam System for Sony E-mount cameras with APS-C crop sensor. This adapter allows you to mount a camera to a shifting board that holds a medium format lens. The lens then projects the 6 x 4.5 cm frame and the smaller format camera can be moved up, down, left, and right to capture a series of images that can be quickly stitched together for an exceptionally high resolution image that mimics that of true medium format systems. This method means that you will not encounter issues of distortion while stitching the image together since the lens image does not move. Also, the unit has a built-in composition screen to preview the entire frame before mounting a camera and can allow the camera to work with large format 4 x 5" camera systems.
