Early Nikon F2, Differences in Construction.

[Sonnar Brian]

The F is a little bit quiter, 1/60th Sync vs 1/80th Sync.

Now- differences in Early Nikon F's, lots of changes occurred that are easily seen.

Brian;

I don't know if this helps.. Nikon had a problem with the F2 in a "pinched" flex-circuit board that traveled over the top of the camera. They resolved the problem by removing the top plate (with serial number) and affixing it to a new camera. It's this kind of service/responsibility that's kept me using Nikons professionally for 30+ years.

I don't know if other changes were made during this "serious" F2 warranty/service period.
The f3 (I still use them for film) was in production longer than any camera in Nikon's history. A friend watched the last one being hand assembled in 2006. There were likely a few changes in the issue over it's run. I know the HP finder was an addition. I had an F3 P and it was much different in construction than a standard F3.
