 It's hit and missAug 18, 2010
When this lens is on... it's really sharp! Problem is, when it misses its completely blurry and the pictures are worthless (which comes out to about 20% of the shots). I don't use this lens very much because I just can't rely on it. Several nice crisp shots followed by one or two really soft ones. That changes when I'm shooting with a flash... it focuses great and consistently.
 Not a good buyJul 30, 2010
I have never had much success with this lens, it will either back focus or hunts and hunts and then when it locks in the subject it is blurred and out of focus. At first I thought it was something I was doing wrong, but after many attempts to use it, I can't afford the risk of it not focusing as fast and accurately as I need it. I have kept in my bag, but now I need this lens and hope to get it fixed if at all possible while it is still under warranty. I would not recommend this to a friend, I would not purchase this lens again.

 Like an L, but cheaperMar 23, 2010
I had researched this lens for almost 4 months before actually deciding to purchase. Like a lot of people that just bought their 7D with the kit lens, I was secretly wishing I had the funds to purchase the Canon 24-70 f2.8L. Unfortunately that lens is a sizable investment when building your kit on a budget.
Thats when the Sigma came in. Sigma has a few lenses in this focal length, all with the same speed (f2.8). One at about a $350 price point, one with an $800 price point, and this one at about $550. The lower price point could be compared to the low end Canon lenses. Fairly quality glass for the price you pay, but very under built (plastic). The higher end lens can be compared to almost the L. Very well built, internal zoom, and HSM for quiet and fast zoom. This lens could be compared to a mid level Canon EF lens. Very well built, just lacking the bells and whistles of the high-end version.
I had a chance to test this lens out on Manhattan Beach in California, and the first thing I noticed was how sharp the lens is between f4-5.6. The focus at f2.8 is clean as well, but does have some soft edges shooting closer to the 70mm range. Still very much a quality image coming out of a lens at less then half the price of the L.
The Sigma 24-70 EX DG Macro has an interesting way of getting into Manual focus. There are two switches, one near the base of the lens and the is the focus ring itself that you pull back to engage. Not too big of en issue when shooting video really since you have no need to engage the auto-focus in video mode, but can take some getting used to when switching back forth from video to still.
This also is big. Not quite as big as the L, but very close. It also has matte-like finish that really looks slick. I love the shape of this lens as well. Really looks kickass on the 7D body. Be prepared to drop a little extra cash on the filters however as the thread is 82mm. The upside though is all the filters you buy for this lens, you could actually use a step-down ring and not have any worries of vignetting as far as I know.
PROS: Very solid build, fast focus, fast speed (constant f2.8)
CONS: No IS (but neither does the current L), slightly soft edges at 2.8/70mm, Large filters needed
If you don't have enough cash to drop on the L series lens, but still want a quality lens, absolutely go for this lens. Very happy with this purchase.
Great range, but a touch on the soft sideMar 12, 2010
i purchased this lens for the lower aperture, and the range of focal length. I use this lens exclusively on my canon 5d, shooting RAW and using the back button to control focus points, and the first time i used it for a shoot, i noticed that the images came out a tad bit soft. after working with it some more, and getting a feel for how it performs best, i have come to trust it more. however, i would not recommend using this lens when shooting in a low-light situation, unless you plan on shooting manual focus.

Worst focusing I've seenJan 22, 2010
I did only about 30 test shots with this before deciding to return it. Not one picture was in focus. I do know enough about depth-of-field to rule that out as the problem. Even at f/2.8, there should be some sharp feature somewhere within the focus rectangle in the viewfinder. There wasn't. Not even once. I've never had this problem with any other lens, ranging from expensive Nikkor primes and zooms to inexpensive Tamron ultrazooms. Lenses have to work, straight out of the box. This one didn't.
