Hi all
Could anyone please tell me if focusing screens from 1960's Nikon F cameras are compatible with later models... and retrospectively, are screens from F2's, F3's, etc backwards-compatible with the F?
The reason I ask is that I can find Type C screens (matte, clear center with cross-hair - more or less suited to astrophotography) available from plenty of places for the F2, F3, etc, but am finding it hard to find one for the "F" as such.
Thanks in advance
Chris
