Hi, I own a Nikon D40 standard kit camera, with the Nikon AF-S DX 18-55mm lens. I've had it for approximately 7 months and I've been shooting photos ranging from street scenes, landscape, architecture, pets, nightshots. I will be shooting a little league game soon, as well as softball/baseball and also soccer. I was wondering if those who have had the Nikon D40 for a while have attempted any sports photography/action photography with their cameras and if you have changed/added lenses, or remained with the kit lens. Any tips and techniques, and any other feedback will be appreciated. Thanks a bunch.
