When i was shooting for my high school newspaper and yearbook in the early 80s, i had a Minolta XG-M. The 'head' photographer had a Nikon. I coveted it. It was black. Mine was chrome.... Nikon wa9s the 'pro' choice.
Later, after college, when choosing my first 'pro' camera, i automatically thought first of Nikon. But, i decided to find out what systems my favorite (fashion) photographers were using, and 10-to-1 it was Canon EOS. I read the (prime) lenses were better for that kind of work, and the AF was great, as evidenced by all the sports fotogs shooting them. I bought an EOS 1-something.
But, even though i still have a Canon as the longest-tenured piece of gear, i always coveted Nikons. So, along the way, i made excuses to buy Nikon film cameras. I just always preferred the way the bodies were designed, and i liked the heritage that survived with the lens mount. I started with an FE2, which i still have. Later tried the F4. An F100, then an F6, then back to the F100 which i still have. An F80. The FG i wanted when i was a kid.... And, even though, with the EOS3 and then 5D, 5D, i remained 'a Canon guy,' I've had many more Nikon bodies than Canons.
