I like to shoot preditor birds, when hawks fly in through the trees you have to be fast, I have always used continous shooting mode and RAW,,,,I know it's not sports, or sports mode, but it just plugs away until I let the shutter stop. I bought my 20D because I liked the LCD screen on the top,,big plus for someone who forgets where the camera was set-up for...Then Chris started talking Primes so I added my 2 cents,,,ohhh. PPPRIMMMEES ,,,Good luck on your buy..
