5 out of 10 points and not recommendedvery sharpFocusing is just painful, no stabilization
All the reviews I've read on this said not to use it for sport. I see why now. I tried to use it for swimming, a fairly slow moving sport (compared to others). I didn't think there would be a problem go by instead of at or away from you. I was wrong. In continuous focus mode on a nikon D300 I could not get the lens to focus where I wanted. I don't have this problem with any other lens.reviewed February 1st, 2010 (purchased for $650)
I have the Tamrom 200-500mm (my favorite piece of glass). I was thinking this 70-200 was a compacted version if the 200-500. It definitely is not. I use the 200-500 for swimming, don't have any problem getting lots of good shots. I just don't need that much zoom at most pools.
I've tried it for other shots, again it does not always focus where you tell it to. I can't check every shot to see if I need to redo it. The shots I did get were great, with out a flash. If this would have focused even close to my nikon 18-200mm it would have replaced it for 90% of my shooting. Instead I returned it.
