I just decided to go out and play a bit and get some Raw files and see what I could do playing with them a bit. The shots I'll post are with the Canon 1D MKII N and a Canon 28-300mm USM IS lens.
This first shot is cropped from a 100% view, then converted to jpg and resized for this site. The original file was 7,820KB. There is a small amount of blurr on the one wing but it was moving at the time so thats to be expected. It was taken at 300mm focal length. From what I have seen so far I'm impressed with this lens, even at night with flash shooting sports.
