I just found this forum while searching for information on sports photography. I am shooting with a new Nikon D70 and I shoot high school basketball. I have been using the Nikon 50mm 1.4 without a flash with pretty good results. I have uploaded an example shot at 1000 and 1.4 using natural lighting. I look forward to sharing tips and learning. This is a great resource. I have include a link to my basketball site. http://www.perpetualbliss.net
