I have dreamed about this lens for so long since some of photographers using it. This is my 2nd L-lens after Canon EF 70-200mm f/2.8L USM, and my 6th lens since I started the hobby. The best thing from this lens is the focal length. 24-105mm is the most useful range. In cropped-sensor camera, 24mm is for semi-wide, 35mm for normal, 50-85 for portrait, 100-105 for telephoto. So it is one of the best walk-around lens for Canon body. It is quite heavy and big, but it looks great on my 40D.What I like:
* Very useful Focal Length. Good for walk-around lens on full-frame body as well as cropped body.
* Weather-sealed.
* Optical Image Stabilized.
* Pro look. With red ring. Good build quality
* Image Quality & Sharpness. But it is not as sharp as Canon EF 70-200mm f/2.8L USM
* Min. focusing distance 0.45 meters to make the Maximum Magnification 0.23x.
What I don't like:
* The maximum aperture is only 4.
* Min. focal length is only 24mm. Would be great if it is 20mm. :)
* The AF is quite fast. But it is not as fast as Canon EF 70-200mm f/2.8L USM. May be because it is f/4.
