Btw, comparing the image quality of a GoPro3 even at 4k with a 5D3 is just stupid.
Why is it stupid? Considering the cost difference and size of camera the comparison SHOULD be ridiculous but it's not, it seems the GoPro will actually outresolve the 5DMark3, shoots to a similar log profile if you're used to cinestyle and has a similar bitrate at 45Mb/s long gop. DoF, lenses, colour, manual control and low light obviously go to the 5D. Rolling shutter, resolution, slow motion, robustness, water resistance, portability, weight all go to the GoPro3. They're very different tools and they're not supposed to compete but the fact a cheap action cam beats it in some areas where it shouldn't should be embarassing for them.
I'm glad Andrew put them under the cosh a bit, though it's a shame they got away with the 25p bit, they should be made to answer how a music video can be sped up to 25p or a wedding can be filmed under house lighting at 50hz or why it's the only camera I know of that's remotely taken seriously that doesn't shoot 25p, including all Canon's other cinema cameras. That they suggest in that answer that they're listening to customers is a joke because everyone has asked them for 25p from the day it was announced, including Shane Hurlbut.
