I have a 10d and currently use a 70-200mm f/2.8 lens. This combo is fine for soccer. However when I take the camera indoors and have to crank the ISO to get good shutter speeds I get tons of noise. Currently I've been shooting volleyball and will move onto basketball here in the coming months so noise is a big issue for me. Now my first question is this- I've heard that the 30d is much better with noise control than the 10d, is this true? Is it noticable enough to warrent a body upgrade?
Now what if I instead bought a f/1.8 lens or two? This should allow me to turn down the iso setting, but how much?
If you had choice between upgrading the body and shooting with the 70-200, or buying a couple of prime f/1.8's and shooting with the 10d what would you do? What will yield the best resultes?
