In reply to Sandstone Stickman:
I am a boulderer/walker but have found the G7X to be really good. It fits (just) in my trouser pocket when I am walking, takes great pictures and has useful control options for when you have the time. You can put it in TV mode (speed priority) and put it on continuous shoot for good action shots - managed to catch me in mid-air on a dyno using this. I have taken videos and longer exposure shots using a gorilla pod and have a magnetic attachment for a polarising filter. I really like the 24mm view and use it a lot for landscapes. I have used HDR mode, vivid mode and star scape mode with good results for the right picture, and often use exposure adjustment, macro mode, and play with depth of field. The ability to use the touch screen to focus is really handy too.
The battery life is ok, but if you do a lot it is worth charging it every day. The macro is ok but could be a bit better, as the minimum focus is a bit far away for my liking. My main annoyance is remembering to reset settings before taking photos - shooting landscapes in macro mode, forgetting that the exposure is at +2 etc, but I guess that is true of all cameras!
The best thing is that I can take it everywhere and still have real control over what the camera is doing. I have an SLR but never use it, and am really happy with the G7X.
