The 8x10 self developing back is designed to shoot and process paper in a large format (8x10) camera. It has the same flange as a standard 8x10 film back, but the film plane is pushed back about 25mm. Each kit comes with 1 focusing screen shim to move your existing focusing screen into the same plane as is achieved with the self developing back. This may or may not require removal of your focusing screen, depending on how wide it will open.

***These are hand made products and all will have some degree of scuffs and scratches from the manufacturing process, they will not arrive as pristine as you might expect from a new consumer product like an x-box.***
