I was at a village fete today where they had a display of a few birds of prey. I managed to get about 160 photos of them with my Canon 50D and 28-135mm. The high framerate and quick autofocus was very useful. I gave mum my old 400D and it didn't give anything near the results of the 50D.
The only editing I've done is a crop and resize. I'm on my laptop which isn't much good for colour/exposure editing.
