Query: SIMPLY AMAZING!

Don't bother with IS - but DO bother with 2.8 - I can't imagine shooting with anything smaller than 2.8 now. This lens is incredible - and everyone thinks you're a pro before you've even taken a shot! : ) My shots are amazing. Speed - amazing. Quality - amazing. Durability - amazing. GET ONE NOW!!!
