H 010 #5 Ode to the Nikon F #5
This accumulation goes on, until one day you realize that you have a lot of F's. This is not all of them, probably another 4-5 in the cabinet (and a F2/some F3's and a FE!).
I usually find yet another F at any swap meet. They are reasonably cheap, always seem to work - and if not, you can often fix them by poking inside with a screwdriver. They can also use Nikon re-laodable cassettes. Lenses are plentiful and whatever focal length you need is available - including modern optics.
