Instax Square Back for Graflok 23 mount cameras

This back mounts on any camera with a Graflok 23 style mount, but is only fully compatible with cameras that have variable thickness (a bellows or modularity), such as: Mercury Universal Medium Format camera Horseman VH, VH-R Graflex Century Graphic or Baby Graphic This back moves the film plane back by 30mm. That's how much you will need to shorten your camera. The back takes standard Instax Square film, has fully electronic, one-button ejection/processing, a built-in LED frame counter, and has a built-in darkslide for easy lens changes and back removal. It requires four AAA batteries (not included). The optional matching ground glass back is available at the time of purchase by selecting that item to the right. Instructions are available here.
