Lens for hockey
I know this has been a previously posted topic, but need some help of my own. I really enjoy hockey, and am interested in getting started with it. I have tried shooting before with my 55-200mm lens but couldn't quite get good images. I use a d5000 and also have the kit 18-55mm lens. Wondering if anyone can recommend a lens for me under $600 and am open to used. I will also need a lens with a focusing motor as the d5000 doesn't have autofocus.
