Looks like Nikon is making some strides when it comes to video. The low light performance is impressive. But until they allow aperture control on these while shooting, I don't think it will work for many people. When i'm filming a wedding and following a bride from indoors to outside, I have to change my settings while shooting and I need aperture control. I can't stop recording to change settings. Hopefully Canon can match the D7100 for video because it looks impressive. I'll be sticking with Canon 7D for sure because of the aperture control but I do wish the low light performance was more like the D7100. The 5D3 gets me there but at 2.5x the price.
