Mr Pierce I am thinking about buying a Sigma 120-300MM f/2.8 lens and would like to know your opinion. I also own a D200 and most of what I shoot is sports. I own an 80-200 f/2.8 which works great but I need a longer reach but don't have the money for a new Nikon 300mm f/2.8. I've read alot about out of focus issues and other problems such as it's a hit or miss if you get a good one out of the box. Your pictures look great, would you mind giving your opinion. Thank you.
