I currently have a d90 with a 18-105 and a 33mm 1.8. I would like a longer zoom for sports and plays/recitals, etc. I had at first assumed I wanted the 55-200, but in looking also saw the 70-300s. I would not be opposed to a sigma or Tamron either. I do like sharp photos and will need vr or is so the shake does not kill me. I read somewhere that the extra 100 does not seem like much. does anyone have both? Which do you prefer? I have about $300 to spend, but may have more after Christmas. Any advice would be great!
