In the late 1990's, I acquired a Contax G1 camera. This was a beautiful little "autofocus rangefinder" camera with superb Carl Zeiss lenses. In 1999, I joined a mailing list devoted to discussing the Contax G series and, when that failed, I started my own mailing list, which ultimately grew to have a thousand members or so.
I also ran The Contax G Pages, a site for sharing Contax G images, which ultimately held 20,000+ photos and had several thousand users at its peak. It had been declining in activity for years when the server it was on crashed and, through my own stupidity, I had not kept adequate backups and was unable to restore either the list or the site.
For those of you that are still interested in the Contax G1 and G2 cameras, however, here are some links to various resources of interest.
