Mamiya Finder Magnifer FD402

The Flip-up Magnifier FD402 from Mamiya enables precise focusing for macro and telephotography by magnifying the center of the viewfinder image to twice its normal size. The images it offers are unreversed and laterally correct. After focusing, the magnifier can be flipped up without detaching to confirm overall composition. It features a built-in diopter correction mechanism with a range from -5 to +3 when used with the standard diopter lens supplied with the camera. Weighing in at only 48g, it features an optical construction of 3 elements in 2 groups.
