Fotodiox Pro 4x5 Graflok back with Nikon F mount &nbsptype_Lens & Sensor Cleaning and an excellent electronic viewfinder-This Fotodiox back lets you attach a Nikon F mount camera to any Graflox compatible 4x5 camera. This won't provide full 4x5 coverage, of course the field of view is limited by the size of your camera's sensor but the mount can be repositioned left and right to adjust framing or to produce images for later panoramic stitching. In excellent condition, with minor cosmetic wear. Includes storage pouch.
