I have one, an L35AF.. and at the moment its the only camera I have!
Only one, an FM3a.
7: F, F3, F801, N70, N90, N80, and D90 :D enough to try out all the different films and screens I want.
I have an N8008s (same as F801s). I love it that nobody seems to like these bodies, because it means I can buy them for $40 on keh. I've had an F4 and F100; the F801 is cheaper feeling but it's also lighter, has essentially the same features, and handles more like one of the Manual Focus bodies.
Entire F series here (minus the F6)
My favorite is still the first nikon I purchased: the FE
Bought an FE in late 1979 and an F2A in early 1980. Still have them. I've also have a Nikkormat FT3 and a Nikon EL2. Have gone back and forth on selling the EL2, which is a larger, heavier version of the EL2 and is a real battery pig.
I dont know how many is too many but I do use them all in regular rotation depending on mood or capabilities. Here we go:
FG, EM, FE x 2, FM, FM2n, FE2, FA, F2, F3, F4, F5, N90s x 2, N80 x 2, F100, N8008s, D5100, D7000, D600, L35AF
That's 22 by my count. Hey, is my wife going to see this?? :(
