The list of things that are crippled on the F3 cs F2 can be very long...
- Awful "+/-" tiny meter display (instead of extremely clear LEDs or needles)
- Tiny, awful LED display (instead of clear numbers)
- Only two mechanical speeds. No battery tester to see how much you've left (unlike Canon F-1 and even Nikon's FE)
- Mushy shutter button, you never know where the trigger point is (unlike the precise F2 button)
- Viewfinder not as clear
- Finder Illuminator never works (it never fails on the F2SB and F2AS)
- You can have high eyepoint or good magnification but not both. F2 gives you both.
- Memory lock button often falls down with age
- Tiny, fragile multiple-exposure lever on akward location
- Confusing control placement, it's hard to remember which one is the self timer switch versus shutter button lock switch (they're identical). If the shutter is locked you might be confused and think the batteries are gone, since the behavior is exactly the same. The F2P fixed this with a mechanical shutter button lock.
and the worst of all...
- Meter relies on glass FRE resistor, which is placed exactly below the flash hot shoe. So if your flash bumps into a wall or somebody bumps with your flash, there's your chance for your meter to be gone because of breakage of glass FRE disc. This has happened before. So the most delicate part is placed where it can be knocked out.
Very extensive and informative list for sure!
I have the Modern or Popular Photography magazine of the F3 review from when they used to completely breakdown the camera to the components. I recall they had discussions with Nikon about the life span of the LCD and apparently at that time they weren't sure how long (months?) and therefore made it simple to replace. Obviously we're well beyond that expected life but both mine are good and I don't recall ever seeing that issue mentioned much - if at all. Anyone here experience that failure?
