David Carr: 15fps played back at 30fps would indeed be "pretty pathetic slow-mo" because it would, in fact, be speeded up.

GoPros are useless in low light and have all the problems of a programmed exposure in bright light because you don't have any control over the shutter speed. No control, as a consequence, over motion blur.

You can't lock exposure either (which would be one way to reduce noise in low light, preventing the camera from automatically "gaining up" when it's pointed at something dark).

The ProTune firmware update helps improve the image in good light but does nothing to improve low light response.

Anyway, at least we know why the ProTune update was so overdue: they were busy making the Hero2 obsolete...

Right, as a snow or surf POV camera, it's great.
But if you want to use it for, say, discrete documentary work it has definite limitations. Just pointing them out.

anthony mazzeri: For all those commenting here about 4K video frame grabs looking like crap, Laforet proves you wrong:

PS: Cheat - the EPIC is actually 5K, but I'll leave the link here anyway.

Yeah, but the EPIC frame grab is made at 1/200th because it was shooting 96 FPS. The Canon 4K is at 24P so that won't be possible.

CameraLabTester: There comes a time and a situation where the camera being produced by the manufacturer is just out of bounds from the common market...

.

24FPS = 1/48 sec shutter speed. This alone limits the possibility of taking useful frame grabs for stills.
That revolution (and it will be a revolution and mark the demise of much still documentary work) will begin to come when we can shoot 4K at at least 50 FPS. That would give us 1/100 sec shutter. Cartier Bresson was at 1/125...
