The action cams don't take the best pics, IMO. Way too wide-angled, although I am to understand some post processing software can fix that to an extent.
Like [MENTION=4588]Machka[/MENTION], I keep a point and shoot either in my back jersey pocket, or the top of my handlebar bag. I can turn it on, take a pic, and put it back without ever stopping. If I feel something is picture worthy, I probably want to stop and look at it though.
