Im the proud owner of a D700 and Nikkon 24-70 F2.8!
Im looking at purchasing a longer lens. I know the ultimate is the Nikon 70-200 f2.8 but at the moment Im not sure I can justify the price. I wondered if anyone owns any of the following Nikon 80-200 F2.8 or Sigma 70-200 f2.8 HSM and could tell me the quality of photos they produce and whether going for the Sigma lens would be a positive move?
