This pair of Nikon F's have become my daily user's...
The first is my original Nikon F bought quite a few years ago, #6424323 with an early Nikkor-S 5.8cm f1.4 #158742, making them both 1960 vintage. This Nikon F has restored my belief in the Nikon F, it has fully recovered from its second burial at the beach with no ill effects. I thought that the Nikkormat FTn was the only camera that could survive such an ordeal.
The second Nikon F is a recent acquisition found in a box lot of stuff bought off the local eBay, #6409109, making it the oldest Nikon F I own, apparently made in late 1959. It is mated with a very early Nikkor-S 3.5cm f2.8 #920429 'Tick-Mark' with a nine-blade aperture.
After several years of experimenting with a number of different formats and types of cameras, I have come full circle and found the Nikon F to be the best camera for me. As a tool, it simply disappears. Oddly, the Nikon F with an eye-level finder is the only camera that I can use thoughtlessly, I do not even second-guess my exposure choice, it just happens.
The Nikon F only requires me to make 3 decisions when making a photograph, shutter speed, aperture, and focus, which happen instinctively allowing me to concentrate on the world through that huge 100% viewfinder.
