Like John_Nikon_F, I also have a "new old camera." Well, actually, both of those cameras came back to the United States in the same box. My Nikon F2SB with the Nikon DP-3 light metering pentaprism also was ministered to by Sover Wong, and there are differences. Upon comparing the results I determined using my equipment with the results provided by Sover from his equipment, this camera really is "better than new" at this time. The DP-3 really did need repair, and now it is working very nicely again. The new ceramic variable resistor really did make a difference. It is nice to have a camera that works at least as well as it did when it was made back in the early 1970s.
Now to think about when to send my Nikon F2AS over to England.
