A Petri 2.8 rangefinder I purchased in 1958 at age 13. (More here.) I'm not sure what possessed me other than my Grandfather had a Leica IIIc (Which is mine now.) and the Petri kind of looked like it. That Petri was just like the one in my avatar.
Argus C-3 Standard rangefinder for $10 when I was 12. Prior to that, Polaroid 100. Three years later, moved up to SLR with a Canon FT-QL. With both cameras, I must have shot a thousand or more feet of Pan-X...
Mine was a Praktica made in E. Germany during the cold war. It had a Hanimex 50 f1.8 lens that fell apart, but the body has been rock solid and as long as you're in the metering range, the meter is still great. I've since gotten a mamiya 28mm f2.8 and a 105mm f2.8 portrait lens with gorgeous bokeh.
The beautiful irony is that now that I know more about shooting (and most of that comes from you guys -- thank you!) I know how to get what I want out of that old Praktica, and don't NEED to use my n90s.
