I shoot a lot of skateboarding, car photos, portaits, and will be doing a lot of soccer this year. I dont really care about the weight. I will be shooting indoors with it also. I'm doing the photos for my highschools newspaper next year. I'm currently leaning towards the 2.8 and investing in a nice little monopod for it. If anyone has had any experience with these two lenses your advice would be very much appreciated!
