And I can recommend an old beauty, Iskra or Iskra-II - both with excellent lens, fully automated frame counter, very pocketable and cool to use. The leaf shutter has a sync for flash, speeds from 1s to 1/500, and 3.5 max aperture. The only problem is to find Iskra in a really nice condition, with frame counter working, and the filters with unusual thread - but as a pocket MF camera, Iskra is a very very good choice.
