I think it was the Rollei 35 which when I saw it in a book in the seventies kick-started my passion for quality compact cameras. And I still think it's one of the most beautiful compacts ever made. Surprisingly heavy too, very solid build.
I just love that you can have a pocket camera which can, within its operating parameters, deliver image quality equal to a big pro camera at four times the size and weight.
Of course the famous Minox 35 is even smaller and much lighter. But in the end it's plasticky and I never felt the beauty of it in the same way.
