When the F4 has a AF Nikkor 24mm 2.8 attached, if the aperture lock ring is "locked", the viewing window inside the Viewfinder looks down at the lens and only displays "22", as the aperture ring is locked there. Presumably, if the aperture ring is not locked, the aperture ring will rotate, and the viewfinder will show whatever aperture has been selected.
For use on new cameras, the aperture ring should be locked.
On the F4, the reason why those smaller aperture numbers are printed on the lens, is so they can be
seen from the viewfinder.
My question is, when used on cameras like the F4, should that ring be locked?
