Title: Great piece of equipment
Review: I can't tell you how glad I am to have finally purchased an "L" series lens. If you are considering upgrading from a Digital Rebel to a 20D or 30D you should definitely try the 17 - 40 L to be sure the quality you have been looking for is not a shortcoming in your current lenses versus you needing a new camera. I did buy a 30D at the same time, and it's a fantastic purchase, also, but my old 300D takes great shots with the "L" lens. I take the 300D with me instead of the 30D to anywhere remotely dangerous and am always happy with the results.
