I dabbled with photography in the late 80's and early 90's, mostly just vacation stuff, a Minolta SLR followed by a Nikon, but when I seriously got into photography in the mid-90's, my first choice, a full electronic camera, arrived straight from the dealer, unused and brand new, completely dead. Not the battery, the electronics. Dead as dead can be. That convinced me I wanted a fully mechanical, manual camera, which at the time left me limited choices -- Nikon and Contax each still had a manual SLR, but I ended up with a Leica M6, really only because my grandmother travelled extensively in the 50's, 60's and into the 70's with a Leica M3. A brother inherited the camera, raved about the build quality and optics, before selling it because he needed an SLR for a safari. Anyway, over the years the M6 eventually turned into an MP and M7, then went retro with an M4 and M5, until finally I got out of rangefinders completely. Back to SLRs for 6-7 years, and this is where I shot a boatload of film, gaining lots of experience, and I also sampled lots of other cameras -- folders, TLRs, ect.
I returned to rangefinders 3-4 years ago, because my back demanded something lighter, my ears wanted something quieter, and the simplicity of a smaller system appealed. Thinking to save $$, I started with Kiev's from the 50's, which led to pre-war Contax, tried Nikons, then I stumbled on an M3. Now I finally understood what my brother was talking about. Something about those old Leicas. Mind you, good pics can be taken with any camera and lens, from any maker, but Leica rangefinders, especially the old ones, are special. Soon my rangefinder cameras morphed into a couple M2's because I've gravitated more to the 35mm focal length over the years.
A strange journey, frustrating at times, but glad I had the opportunity to use different camera systems.
