I owned the EFS 17-55 2.8 IS before I switched to full-frame.
People, quit asking about this lens already!!! I am getting sick of it.
Get a few things straight:
1. The EFS 17-55 is what ALMOST stopped me from switching to FF.
2. FF owners are still waiting for the FF equivalent of this lens. 24-70 2.8L IS anyone???
3. In my opinion, it is the BEST "walk-around" normal zoom available anywhere! Period. (I bought and sold the 24-105L for the 17-55!)
4. It is sharp, sharp, sharp. And fast, fast, fast!
5. Yes, it IS WORTH its asking price. JUST BUY IT ALREADY!
6. Build quality/dust issues are minor.
