Instant Film Square Back for Graflok 23 mount cameras

This back is compatible with Instax Square film*.  It 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. Mercury cameras can be configured to be compatible. On bellows cameras, you can move your front standard back by 30mm. Other cameras with no variability (Mamiya RB67, Graflex XL, etc.) are physically compatible, but all lenses will act like macro lenses, for very close subjects only.

The back 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.
