New Autolocker back!!
Here is the latest back design!! I have made more improvements to my 4pt design. In past designs the thickness of the holder had to be adjusted manually . Now with this design it automatically adjusts to the thickness of the holder. Now it is possible to go from a double-sided film holder to a Polaroid 405 or 550 back with out any manual adjustments.

is it possible to use grafmatic holders?

Hi Albert, yes it is possible, the grafmatic holders are based on the 4.5 mm base platform system. the rails fit in the grooves and lock it into place. The other model that I made, the back was made out of resin, but this model is a lot more user friendly, thanks for your question..david
