I'm currently testing a Canon 800mm/5.6L IS lens and a Canon 1D Mark IV camera. I shot this Timbers game at ISO's from 2500 to 5000 as the light changed. I was very impressed with the focusing and handling ability of the lens. It's is a large and long, but not that heavy. I think a 400/2.8 is more difficult to handle. I especially like the reach from at the goal. What it was perfect.
