When I was a junior in high school ('59-'60), I was working for a photographer and a good friend was our HS Annual Staff Photographer. My buddy Bill was using a Roleiflex and a huge strobe with an even larger battery pack for his annual photography.
I noticed that Sears had what looked like a pretty good camera -- a "Tower by Olympus" -- and bought one. It was a 35mm rangefinder camera with an f2.8 Zuiko lens. I started taking it to school and people got used to seeing me with it and quit "posing" for pictures. I was using Kodak Plus-X film at ASA 160 and getting some great candid shots. Before I knew it, I was on the HS Annual Staff. My boss saw some of my shots and got interested in my camera. He did some lens resolution tests and learned that my $69 Tower by Olympus' lens was as sharp as his $400 Leica's Zeiss lens. That camera worked great until my son was carrying it by using its neck strap as a hand strap and swung it into a rock in Yosemite NP and busted the shutter in '79.
I just bought an Olympus camera again and the quality is still superb. But the price has gone up a tad. Just the camera body cost me $450. By the time I bought a base lens (14-42mm zoom) and a telephoto zoom (40-150mm), I'm into the system for close to $700.
