Mamiya Accessory Flip-up Magnifier for the Prism Finders of the 645 Pro, Pro TL and Super Cameras.

Attached to the prism finder, it assures enhanced precision focusing by magnifying the central portion of the screen 2 times. After focusing, flip it up for normal viewing.

Featuring 5 lens elements in 2 groups, it produces an unreversed and laterally correct image. Particularly useful for critical focusing with wide angle, telephoto and variable soft focus lenses, as well as for copy work and macro photography. Built-in -5 to +5 diopter correction. For AE Prism Finder and standard Prism Finder.

To attach Variable Diopter Magnifier, standard eyecup is removed by sliding upwards.
