Yes, it's great fun. The main reason for getting this photo equipment. If it weren't for the fast action, a P&S camera would probably work just fine. But, I like to shoot my daughter's activities as well as support the kids High School.
Tried my had at shooting basketball. Now that's a difficult thing to do. Terrible lighting, fast action, and you rarely have the right lenght of lens. Wish they made a 50-125 F2.0 lens!!!
