What’s this world coming to? eBiggs is recommending a 6D, a camera he said he could never recommend to anyone, and I’m going to not recommend it.
I own a 6D, I think it’s a fantastic camera, and I think that (with the exception of well lit scenarios), the difference from a 50D is huge. I think calling it an entry level full-frame is misleading at best, as it makes it sound like a beginner’s camera, which is nonsense.
All that said, the 6D’s Achilles heal is the focus system; the 6D is not designed for sports. I’ve captured sporting events with my 6D, and it works, but the yield isn’t going to be as high as other options. If your primary use is sports you should have a good look at your needs and budget. Unless you have the cash to step up to something like a 5d3 or 1dX, you’re going to have to make a compromise. Do you push the limits of the high ISO performance of your camera, or the autofocus system?
Although the 6D will allow a significant bump up in ISO performance, you have an AF system that wasn’t designed for fast moving subjects, and you have the “anti-crop” factor of a full frame. Usually in sports you always want more reach, the 6D will give you less reach than you’re used to on your 50D, and getting it back can be a very expensive process. By the sounds of it I think you need to research full frame, and EF telephoto lenses before you make a switch.
Alternately, perhaps you invest your money in a decent telephoto? Something faster that can allow your current camera to shoot a slightly lower ISO. As I said, it’s a compromise. If you want to go full frame be prepared to spend at least $3,000 to get a reasonable sports setup.
