I like rangefinder cameras because they're what I really learned with.
In High School, in Chico, California, in 1978, my photo teacher had a whole fleet of Nikon S cameras for the students to use. These things were hammered, having been dragged around for years by students. They took really good pictures, and Mrs. Wismer taught us to use our "Mark I eyeball meter". She gave us the simple directive:" f16-1/125th outside, f2.8-1/60th indoors, bracket like crazy". After we could make good reliable prints for her and the yearbook, only then could we graduate to SLRs and zoom lenses.
After a few kids, a couple of SLR's and a lot of Ho-Hum photos, I realized the need for a rangefinder again. When I went shopping on E-boy for another Nikon S like I used before, I saw the prices and nearly fainted. I researched rangefinders and found the FSU cameras available from the Ukraine, and now have a couple of useable FEDs and a couple of lenses, and have felt my photos to be more satisfying.
My kids are curious too, about Dads funky looking cameras, and I've found that teaching them has taught me just as much.
