re: Focusing rangefinders vs. SLRs
That varies a lot with both types. I just checked a few of my cameras and lenses, and my Canonet QL17 rangefinder does have the shortest throw from closest to farthest focus of those I checked, but the next-shortest was a Zenitar 16mm SLR lens, then a Tamron 24mm SLR lens. The standard 50mm Industar 61L/D lens on a FED 5 rangefinder has roughly a 180-degree turn for full focus range, which is similar to that on my Fujica ST-801 SLR's 55mm standard lens.
