I've shot film for years and digital for less than a year. Because you can learn quickly from the instant feedback of digital, I finally tried shooting sports action. It is quite a challenge. You need fast lenses, high ISO, and a good eye for action.
I started with local women's collegiate basketball. The lighting was fair. Most importantly, there were no barriers to getting down close to the action. Here is an example of selected shots from my "work in progress."
