The Mamiya FD-402 Magnifier aids in critical focusing situations by magnifying the central portion of the focusing screen.
Note! This magnifier only enhances the central part of the focusing screen
This is especially useful for any kind of manual close-up, macro or copy work because this item provides a twice normal (2X) magnification of the central area
It is attached by merely sliding it up into the camera's viewfinder and securing it with a locking lever
Diopter adjustment is also possible with a range from -5 to +3 to accommodate near or farsighted vision
