1956 A2 rangefinder
I have a "Super A" in fine condition after a CLA about 10 years ago. Have only used it once or twice and not recently. Mine has an 1.8 50 mm "normal" lens and I also have a 4.5 135mm lens. The telephoto uses a separate viewfinder that fits into the accessory shoe on top of the camera.
Remembering that it was a bit tricky changing lenses. Someplace I have the instruction booklet for it but not sure where. All in all an interesting range finder camera introduced not long before SLRs captured the market.
Quite a sturdy camera.
