FOR NIKON F and F2
Matte/Fresnel field with 3mm diameter BriteView (horizontal) split image rangefinder spot surrounded by 1mm wide microprism donut.
Rapid, accurate focussing for subjects with both straight and ill-defined contours.
This is the standard screen that came with the F2.
The microprism donut is genuinely useful, and the split-image gives great results when used with unforgivingly shallow-DOF lenses.
The screen is in great shape, and comes in its box (as in the photos).
