What a great photo. I have a 10D also and often use the 10-200 for outdoor sports, but these kind of shots are not easy to catch!!! You did a great job here!
Dave, thanks for the advice and good words. Julien, actually I focused on the first girl but when they moved autofocus jumped to the second girl the moment I pushed the release. And I actually like it that way :)
Alex, it is a really nice picture. The ball motion is clearly visible and the concentrated expression on the player faces is well captured as well. And...Dave, I do think that the second player is the main subject of Alex (c.f. portfolio). Regards, Julien.
I've tried to do these for years, and I feel qualified to say this is outstanding. Certainly this kind of image is hard to achieve. Your focus is best on the second player, but it doesn't seem to matter here. Can you rate the 10D at ASA 800? If so, you might have had enough light to allow you to close down a stop.
