I recently bought a used Ricoh GX100 for the times when the M8 is too big. The manual controls aren't bad and there's a little shoe-mount EVF which is a great deal better than trying to hold the camera at the right distance for my varifocal spectacles. Since the lens can zoom to set focal lengths (e.g. 24, 28, 35 EFOV) you can even use ordinary external finders.
Results are not up to the standard of a good DSLR but are infinitely better than the little Pentax P&S I had before and good enough to post on my website (only two so far, in among shots from other cameras at
jn : photos : Odds and Ends).
And as others have said there are some small film cameras with good lenses. I have a Rollei 35 (a couple of pix among the M8 shots at
