Originally posted by boriscleto Quite right. As an aside, I once owned a first-edition 1934 Kodak Retina, the camera for which the 135 cart was designed (or they were co-developed). I'd already been shooting for 15 years, but the Retina was my first serious camera, and it really taught me photography.
The original Retina was just a little folder with 50/3.5-22 lens, 1/500 shutter, X-sync contact, tiny viewfinder, spin-the-lens focusing, and nothing else. No rangefinder, no hot.shoe, no metering, no automation of any kind. But I learned to judge distance and angle and light and form; learned to look at a scene and automatically adjust the few controls (focus, aperture, shutter) for the exposure -- a human-powered P&S with professional results. Mine was stolen long ago, but I now have a near-clone, an inherited Voigtlander Vito II.
Another aside: A year after my Retina, I acquired 135/HF (half-frame) cams: Canon Demi-EE18 and Dial35, and the Olympus Pen-FT SLR system. (And I now have an inherited Universal Mercury II CX, a 135/HF ILC RF with 35/2.7 long-normal lens.) The 135/HF frame is 24x18mm, half the size of 135/FF (imagine that!) and almost the same as APS-C. So I've dealt with crop-frame 135 cameras for over 35 years. No big thang.
