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 -6 to +4 diopter correction. For Prism Finder Model 2 and PD Prism Finder.

Diopter Correction Lenses
Anyone wearing eyeglasses or experiencing difficulty focusing may benefit by adding a diopter correction lens to the viewfinder. Diopter correction lenses adjust for near or farsightedness and permit your eye to more clearly see the focusing screen, thereby enabling you to achieve consistently sharp photographs.
Although it is possible to consult your eyecare specialist to ask for your "diopter correction" number, in our experience it is best to try it for yourself. To make it easy for Mamiya owners to explore the benefits of a diopter corrected viewfinder, complete sets may be ordered with return privileges. Keep the one that works best for you, and return the rest within 10 days.
