As a still vaguely loyal Canonista I have followed the build-up to the G1X release and eventually decided that I had to have one. After my first week I have to say that I am generally quite happy with the camera, and extremely happy with the handling and image quality. Firstly, the G1X is not a baby EOS, but is instead a purebred G Series compact with a big engine under the hood. This applies to everything from operational speed, menus, controls, and customisation. An EOS gets on with the job with a minimum of fuss. In comparison the G1X works to it's own pace, just like it's G Series forebears. It is actually a very good reminder of how truly great the Micro 4/3 implementation of live view and CDAF really is. The G1X is not bad, but far from class leading. The sensor and lens work extremely well together and once I'd gotten a handle on how to optimally convert the CR2 RAW files to tiffs in Canon's DPP software and export to PS and Color Efex/Silver Efex, I am extremely impressed with what I am seeing so far. To string together a series of ifs; If Canon use this as a basis for a mirrorless interchangeable lens camera, if they get a better handle on live view implementation and CDAF, if they back it up with a timely release of compact lenses, then Micro 4/3 could eventually be facing their stiffest competition yet. The G1X sensor is only marginally bigger than the m4/3 sensor, and the G1X applies the same kind of lens correction software as used widely in the m4/3 system which bodes well for a similarly compact system of lenses. Incidentally, the G1X's lens-based IS is just as impressive as that in their better EF lenses, which goes to show that you can make a working IS system in a collapsible lens for a large sensor compact camera... Maybe I'm "iffing" just a bit too much, but creating a mirrorless system that will be in competition with their existing DSLR system is less of a risk than Canon took 25 years ago in mothballing the FD system and creating EOS. In the meantime, I am enjoying my G1X (and my Micro 4/3 system!) very much.
