My favorite fixed lens, full frame, 35mm, small, non SLR type camera is the
Rollei 35 there are a few variants that greatly affect the price but they are all pretty good. The camera is technically a "rangefinder" but it does not have a coupled range finder mechanism you actually need to guess the "range" to the subject to set the focus. Its an acquired art but not all to difficult. The german made variants are perhaps the most expensive but the build quality reflects the price. It also happens to be one of the smallest ever made and has a neat little fold up lens.
There are lots of mass production cameras like the Minolta, there is the
Olympus Trip the
Canonet. Then you move more into the modern pocket cameras like the
Minolta TC-1 the
Nikon 28 and 35 TI as well as lots of others made by Leica, Nikon, Canon etc. A lot of these are all very similar in build quality, were intended as pocket cameras that are easy to use and take around. Lots of info out there on them and in a lot of cases I have always felt that quality took a back seat to portability on these kinds of cameras.
