The Zeiss ZMs have joined the Contax G Redundancy Club.
Way back when (2006) when I traveled around Asia with my two G1s, I saw a fair number of shooters with ZMs, mostly Japanese tourists. They always had several lenses but were able to carry their kits in small shoulder bags, which I envied.
As for the cameras, I admired them but by then I had invested heavily into the Contax line. My dealer in Melbourne once assured me that the Contax G Zeiss lenses were "as good as" and I should be content with my kit. Which I was.
Fast track 18 years. Both the Contax Gs and the Zeiss KMs are now relics. Fantastic lenses, not so good bodies. Few if any repairs now available (my repair shop insists that nothing can be done to a Contax G's electronics when they pass away) and the few cameras in both lines I occasionally see on secondhand gear shelves sell for very little. The lenses never seem to end up in the shops. On the other hand the Reissues have held their value but I've not seen one on offer for the last decade. Their owners must cherish them and keep them forever.
Too bad I didn't buy into that range back then, but as usual for me I didn't have the $$$ and the Contaxes were far cheaper. One lives and one learns, I reckon.
