I been using my camera for about a year now and now I shopping for new lenses. There are just so many lens on the market, each is designed with compromises based on laws of optical physics. It’s not an easy task shopping for the best buy. I discovered the forums on dpreview.com make me even less decisive; these opinionated folks just go back and forth endlessly.

I found this a Canon EOS FAQ to be extremely helpful. It’s just non-nonsense, comprehensive and up-to-date. It’s a beginer’s FAQ so it’s easy read too.
