Hi there! I do indoor sports photography and I am wanting to upgrade my camera. I am really outdated with my camera right now...it's a d90 so that's why I want to upgrade. Prior to my d90, I shot Nikon film cameras so I'm still new to the digital world. I've considered the d3...any objections to the d3 for these purposes? As far as budget, I'd rather not pay over $2500/$3000 (new). What suggestions do you have? Lenses I have are Nikon 18-105mm, Nikon 70-300mm and Nikon 50mm.
