I happen to own both those cameras and I can refer you to some video shot with each so you can judge for yourself. I'm a fly fishing pro staff and shoot video both for fly casting and fly tying. I find the Canon to produce a better image and has more manual controls. The Sony is definitely better for 'run and gun'.http://www.youtube.com/watch?v=5BFfasV7Fqg
My lighting is not very bright (I have to get brighter CF bulbs), so we're getting into the lower light ranges of the cameras, hence a bit of noise in the Sony, which isn't a low light happy camper as this review points out. To give you an idea of light intensity, I don't have light meter, but for this scene my DSLR requires an exposure of f2.8 at 1/5th of a second using ISO 100.
The CU of me has been done by the Canon, while the fly against the orange-red background has been done by the Sony. The CU of the fly from behind was done by an Olympus TG-1 P&S camera.
Watch the video full screen at 1080p.
Here's a second video shot completely with the Sony, but unfortunately at a much lower res. Anyway it'll give a taste of it's outdoor performance: http://www.youtube.com/watch?v=19PvAgTF4tE
