I was recently helping a guy get some better camera angles at a live performance in a record store, and I have a Nikon d5100 and he has a Canon crop-sensor camera, but I can't remember what it was called. There was not a lot of light available. He had an 85mm 2.0 and I had a 35mm 1, 8. We both shot at 30fps 1080p and similar exposure.
But his video looked almost perfectly clean while mine had noticeable noise. I don't know if he's going to be able to use it. Why is this the case for video? According to DXOmark, the Nikon d5100 has the best low light ISO capability of any APS-C camera except 1 Pentax one and most of the Canon ones are much less capable, so it must be exclusively a video thing.
