Here is a real world video test of the Nikon D600. Shot at the Mastercard Centre Arena (inconsistent fluorescent lighting) using the following settings: Full manual mode on a tripod, 'Standard' Picture Profile, 1080 30p, Shutter Speed 60 frames per second, ISO 640, white balanced to the ice, Nikon 24-120 F4 lens at F 6.3, manual focus at infinity, on camera microphones. Split screen comparison followed by a full frame example. Watch in HD for best results.
I just wanted to put this up for people to see how well this camera handles the lighting and how well it reproduces the colour. I usually shoot hockey video on my Canon XF100 camcorder, and I love the 50 mp/s recording bit rate/codec, but the Nikon blows it away in terms of colour saturation, white balance and overall picture quality. There's a little bit of soft focus on the zooms but that's my fault, not the camera's. I did a very slight S-Curve colour correction in Premiere Pro CS6 and there is a Sharpening factor of "22" added to the final output.
I hope this helps anyone considering using a DSLR to shoot an action sport like hockey. I bought a physical zoom lever arm to help the zooms and it has been a big help. Ergonomically, it's still much harder to use than a camcorder, especially when there is no LANC or power zoom option, but the image quality sure is nice.
