Fantastic Lens, especially when clarity counts
This is a fantastic lens that has the ability to make any photograph better. The real beauty of this lens is that, in my experience over the past 18 months, the impact of this lens is directly proportional to the quality of the picture taken. That is to say, its effect on mediocre pictures tends to be marginal, if you really look you'll notice a minor improvement in detail and crispness. Take a great picture, something with a lot of details that demands clarity, and that's when this baby start to shine. The more challenging your subject, the more you likely you are to be impressed with this lens.

Nothing in life this good comes cheap, and the costs of this lens are measured in more than just the typical "L" class price tag. As is typically the case with any of the Canon "L" lenses, it is significantly larger that what one might expect a lens of its power range to be. This was the first "L" lens I ever used. When I took it out of the box I though someone had shipped me a 200mm lens. This is a BIG lens for its class with a substantial girth -- the product pictures do not begin to do it justice. It's also a heavy lens, even taking its size into account. This needs to be kept in mind if you are considering using this for your "normal" lens -- which I do. A final consideration is that when this lens is paired with a camera configured for 1.6X field of view magnification, which most Canon digital SLR's are, the 24MM wide angle really doesn't get very far into the wide-angle range. In these cases the lens functions less like a wide-angle to short-tele zoom, and more like a normal to short tele zoom, with a hint of wide-angle capability thrown in for good measure.

Taking all of this into consideration, it is still a fantastic lens. It is difficult to imagine any photographer, pro or hack, not being pleased with it.

Fast, Solid, Incredible Build Quality. Takes Fantastic Pictures!
I now own 4 "L" lenses (see below). I can't think of a single downside to this lens. It is fast, quiet, and the 24-70mm is a great range. On my 40D with a crop factor of 1.6 the lens has a 35mm equivalent of 38.4-112mm. A really nice range. The lens is great for portraits but does so much more. Highly recommended.
