Canon EF 17-40mm f/4L USM

I've had the 17-40 for a little over a year with the 20D and get excellent results nearly every time I use it. It is the sharpest lens I currently own. It is also the fastest to focus and nearly inaudible. I also like that I can use auto focus and then manually adjust to alter where the dept of filed will fall. My only real issue is the flair, which is not helped much by the hood. I often have to hold up something to shade the lens when facing toward the sun, but I expect I would have the same problem with any lens this wide. For the price, it can't be beat!
