Today was my first time shooting some lacrosse games, and the first time using my new 70-200/2.8L IS.
I'm pretty happy with the lens so far. A little on the short side though for large field sports, but I think it will perform well with a 1.4x extender for about a 100-300mm f/4 IS which is a better range for lacrosse and soccer on a 20D.
