Screen image is split with diagonal slants
Hello Sashaone,
The F3 has the most extensive selection of focus screens ever made
for a Nikon camera - 22 in all. The "L" and "P" will give you the
diagonal split image rangefinder that you love. The difference is that
the L has a groundglass/Fresnel lens field around the split prisms. The
P has a microprism collar and an inscribed horizontal and vertical line
forming a large cross.
You should also be aware that with slow
lenses with maximum apertures of f/5.6 or so, these prisms tend to black
out. Here, Nikon has solutions too, including the R screen, which has
gentler slopes on the prisms to combat blacking out with small maximum
aperture lenses. The R also has grids to help with composition, similar
to the E. Then there are the all matte, all microprism, aerial image
screens (C, M) too.
Personally, I have the C E K M R screens, in alphabetical order.
Some
subset of these screens are available for the other Nikon F series
cameras (F, F2, F3, F4, F5, F6), as well as the FM2, FE2, FM3a line,
which can also interchange screens.
Thanks.
