I‘m Back MF 6×7 CM LONG focusing screen.
Compatible with the following 6x7cm I’m Back MF adapters:
The focusing screen is where the image is registered on the I’m Back MF device and therefore it must always be clean. Many times, the shutter itself, because it has dust inside the camera, can deposit small residues that, if not removed, will be recorded in the photograph. To clean this surface, use an air jet and, if necessary, alcohol. Avoid contact with fingers as it may leave an oily stain on the surface.
