Eyepiece Correction Lenses

Finder Eyecup

The nine eyepiece correction lenses are designed to permit nearsighted and farsighted users to view and focus without their glasses. Available in - 2, - 3, - 4, - 5, 0, +0.5, +1, +2 and +3 diopters, each representing the combined dioptry of the lens and the finder. Simply screw into the finder eyepiece.

The soft rubber finder eyecup screws directly onto the finder eyepiece to prevent extraneous light from enter- ing the viewfinder.

When using an eyepiece correction lens with a finder eyecup, it is recommended to use the Nikkormat type eyecup. First, fit the lens into the eyecup in advance. Then screw the assembly onto the finder eyepiece.
