If you do not want to go ILC, well, yeah, you will likely just have to get another G11 . As to ILCs: you don't have to change lenses, you know <ROFL>.
For me it also was about downsizing, to a degree. I now only have 3 digital cameras and a single analog camera left, and that was 5 and 5 just before Christmas, with 45+ lenses; the latter has more or less halved .
Kind regards, Wim
