The choices are the from the cheapest, Sigma 70-200mm F2.8, to the best of the Nikon 70-200mm F2.8 VR. Here are the links to both to give you price difference.
For outdoor sports, you can add a 1.4x teleconverter to the lens, which would make it a 98-200mm F4 lens.
I have a DSLR (Nikon D90) camera. I'm in the market for a telephoto lens to use taking pix of my kid's sports; mostly indoor, but sometimes outdoors. Something easy-to-use that would give me good pix quality is my goal... but I'm not a pro and don't want to break the bank buying a $5,000 lens.
I'm not sure if this is possible, but any and all suggestions welcome for this camera newbie... thanks
