I started with a Spotmatic, bought it used with a 3 lens kit at a Pawn Shop in Long Beach Ca in 1966, liked it and still have. In 68 I bought a Konica T because I wanted a body with shutter speed priority and after reading many reviews found that the lens were all excellent. Then in 72 I needed a camera with a motor drive, I looked at Nikon, Canon and Topcon, decided on a used Nikon F, traded my Konica and lens in for it. As I working PJ I kept with Nikon, F2 and last a F3. Once hooked into the lens mount could not afford a new system every few years, the object was to make money not to spend it. I did come close to dumping the F2 for a Pentax LX, once again cost of new lens. Right after 911 my gear was ripped off at LAX on a return flight to Phoenix. As I was shooting medium and large format I did not replace my Nikon, gave the FG and FA to my son and shot with my M42 gear. Then on a whim I bought a Sigma SA7 with 2 lens at a Kit's Camera at a local mall. Although not a perfect camera it as cheap and worked well enough that I bought a SA 9 and added to the lens kit and added a SD9 and 10, then 14. I was a happy camper, then the SA7 and 9 died from the yellow death. I looked at returning to Nikon, maybe Canon EOS, but decided on Minolta A mount, the lens were very reasonable and the bodies are dirt cheap. So I don't have brand, it has always been a balance of my needs and costs. I would be happy with a F5, EOS 1V, just a matter of costs.
