Well, I've read the first link, and I find little with which to disagree. I have already stated here somewhere that my printer lies talking to itself 24/24 and costing me money to do that; I have little intention of dumping the D700 and even kept the D200. I pulled out the F3 last night, stuck on a lens, and put in two little batteries. Of course, they didn't switch the thing on: the batteries, though new in their Kodak shrink package, have slept here since 2005.
On holding the camera to my face, the viewfinder was very blurred, which confirmed my findings of a few days ago when I also played with it for a moment. The diopter correction glass was a +0.5. I took it off, found the original one (has no marking) and to my astonishment, it was almost crisp enough to use, and the split-image certainly would have made the camera operable again. I had noticed a while back that since the discovery of my glaucoma and the use of daily eye-drops, I no longer needed reading glasses, my constant hated companions since around '83! So bright sides do exist.
With or without glasses, the viewfinder of the F3 kills that of the D700 ever time. As for the D200...
