I've been shooting with my 60D for a while now, which I initially bought because I liked the combination of video performance (first) and still performance (second.) As time has gone on, I've realized that I shoot sports/action stills far more often than video.
So I'm thinking about looking for a 1D2n as a primary sports body, and relegate my 60D to wide focal length duties. I've been looking at the old reviews and I'm a little torn on whether or not it will be a camera I can use as much as I want to because of ISO limits. I love the burst speed and the higher buffer size of the 1DIIn, but I don't like how expanded ISO only goes to 3200. With my 60D, my complaints are with the inconsistent AF in low light, lack of auto-focus points and high ISO noise. I regularly find myself shooting sports under artificial light, both indoors and outdoors. The FPS and buffer on the 60D are just barely adequate for what I'm doing, and I would love to see an improvement in those two features.
Will a 1D series camera with a larger sensor offer greater usability at 3200 ISO than my 60D will at 6400 ISO? Sometimes I'm forced to underexpose at 6400 ISO on my 60D and the resulting images are typically awful after pushing the RAW file in PP. This has been forcing me to lower my shutter speed which is introducing unwanted blur.
If it helps, I'm already shooting relatively fast glass wide open. I've primarily been using a 70-200 f2.8L (non-IS) as well as a 50 f1.8. I could switch to faster primes, but I prefer to follow the action on a field, and that could become difficult with a fixed focal length.
Anybody here with experience handling both cameras in bad light?
