The Pro Sony Large Format 4x5 Adapter from Fotodiox allows you to attach your Sony SLR or DSLR camera onto many types of 4 x 5 cameras. The offset adapter allows you to move your camera's sensor vertically and horizontally so you can take multiple photos covering the entire 4 x 5 back and then stitching them together with software. Incremental markings help you position the camera and a tension screw lock keeps your camera from moving while shooting. You can also shoot only in the middle of the back, thereby shooting in the sweet spot of the lens, giving you edge-to-edge sharpness. Additionally, it will provide infinity focus for lenses 120mm and longer.
