Canon EF to graflok adapter.

thingiverse

First design! An adapter to connect my Canon 7D to my Graflex RB 5X4 and my Graflex Speed Graphic 5X4. Fits both my old cameras as well as the 7D. While it does work, it has its limits, very hard to focus on the RB due to the shift in focal plane and vastly reduced "sensor" size. The speed graphic has a more moveable front standard, so its a bit more workable, though it has to be pushed back almost all the way. I may try and design a recessed lensboard for the RB to compensate.
