Thanks Liza, I agree #5 is probably the best. But here again the action is almost directly in front of me. I believe, and I could be wrong that on other shots that I have taken with my 85mm, that my focus was much better when the action was comming directly to me or going away rather than when I have to pan the shot. Perdicive focus in AL focus does do this a bit better in the former. But I notice in the 85mm because I can 1-Set and get a faster shutter speed, 2- don't have to use a higher ISO. and lastly, swing the bigger, heavier lens that my pictures are much sharper. The 85mm usm is also much faster to focus as well. Poor old 10d isn't quite as fast to focus as a 20d or any Mark I series camera. But it's still a very capable camera. Hey, I'll admit it I need more practice, and I'll get it on Thursday night.
I do like that idea of the 100mm and then going to the 85. It would really teach you how to compose the picture and probably give the impression of wide angle after using it. I figure a 85mm would give you a 135mm perspective on a 1.6 crop and a 160mm on a 100mm, that a quite a change in perspective.
Again Thank You.
