Well, seeing this thread brought back reminded me just how long I have had my Zeiss Ikon ZI Rangefinder camera. It doesn't seem like it has been that long. The camera has given me nothing but pleasure, and no troubles of any sort during the I guess five years since I began using it (one of the early "limited edition models). Similarly, my collection of ZM lenses have also been trouble free while producing lovely (to my biased but kind of critical eye) results. I have never regretted selling my M7. The ZI just does it all, quietly and well, from 21mm on up to 135mm. Happily and highly recommended to anyone considering a rangefinder purchase (no Zeiss connection here, though I do wish I had one).
