I've had a lot of fixed-lens RF's, and still have a lot of them. Konica S2 for one of the best lenses, Minolta Hi-Matic 9 for just as sharp lens and more reliable electronics, Lynx 14e for speed.
The Canonet Ql17l and Ql17 GIII are probably the best all-around cameras. The short throw on the release is great, the VF/RF is great. Lens is not as good as the Hi-Matic 9 or S2, but is quite good at F4. Some are better than others.
