A few weeks ago someone posted a message saying that you could put F4 screens into an F3 and you could also put F4 screens into older F2 and F cameras providing that you used the original F and F2 frame assemblies. The question is, which are the brightest screens that are available for my F3? Which are the brightest F4 screens? Are the screens for the F4 really brighter than the F3 screens? Is anyone using some of the 3rd party bright screens, such as the Beattie screen, in their F series cameras? How do you like them compared to your original screen? Are they brighter than Nikon's brightest screens? Thanks Robert Hudyma, Semi-Tech Corporation, 2800 14th Avenue, Suite 511, Markham Ontario, Canada L3R 0E4.
