One of my all-time favorites is the Agfa Optima-Parat. It has a Solinar lens that is very sharp.
I've shot a lot with this camera. I always use it in the case, because the metal body is very slick. Almost too slick.
I have
a review of the Optima-Parat here, plus a link to some photos. I have other photos from this camera, but I didn't make more slideshows. Got busy with changing jobs, relocation, etc.
If you like square photos (and have enough money), there is also the
Zeiss Ikon Tenax II.
There is a
Tenax I, which is a much simpler camera with a lesser lens. A postwar East German version offered this with a Tessar lens. And following that was the Taxona, which also is a compact camera with either a Novonar or Tessar lens. I don't have a review of the Taxona, although I've shot with it.
The Tenax II has either a Tessar or a Sonnar lens. The Sonnar lens, which is uncoated, is exceptional. I've shot the heck out of this camera. Love it.
If you're really looking for compact, there is a Pentacon Pentona with a very average lens, and a Penti, which often can be found in gold metallic. You'll need the Agfa Rapid cassettes, which you will need to load with film yourself, to use the Penti.
