I was looking for a multipurpose lens for vacation to mount on my 7D when I stumbled upon this one. I had seen the reviews for the new Sigma 35 f1.4 Art Series on canonrumors.com and was very impressed with what I was reading. So, I thought I should give this lens a try. After all, it was a mere $499 vs. $2100 for the Canon 24-70 f2.8 L II with which I have spent some real world time. You see, I have just under 100 weddings under my belt in the past 6 years. Yet I haven't ever owned a zoom lens, since I shoot weddings primarily with fast primes (Canon 24 f1.4 L, Canon 50 1.2 L, Canon 85 f1.8, and Canon 100 f2.8 L macro). At times, I have rented zooms when I knew a certain event would require shooting without carrying multiple bodies or changing lenses. I have shot with the Canon 17-55 f2.8 IS and the 24-70, and I must say... this lens competes very well with both of them at a much lower price!
The Sigma 17-70 f2.8-4 DC Macro OS HSM has a longer ranger than the Canon 17-55 IS, while still offering you image stabilization, which the 24-70 f2.8 L II does NOT have! And if it did, just how much would Canon think they could charge you for it? That lens already costs as much as my first car!
In conclusion, buy this lens if you are looking for sharp optics, fast focus, and a decent amount of aperture to boot. Check out my sample photo of my wife cutting the neighbor girl's hair... I took it from my desk, hand held at 1/60, 70mm f4, indoors with only ambient light, OS on, and at ISO 6400. Its not a great composition, but you can see the excellent color rendition and clarity of this glass.
Very happy.

This is the latest version of the Sigma 17-70 2.8-4 DC Macro OS and the most important thing I can say is this lens is phenomenal. With Sigma's recent update to their product line, this lens falls in the Contemporary class. The build quality is beautiful, I like the feeling of the new plastic they are using, and the "sticky" or "tight" feeling that happens on the zoom ring is gone. It is a wonderfully smooth lens in its operation.

The auto focus is smooth, quiet, and accurate. although this lens still lacks full time manual override. The OS is quick and snappy, I can say I am very happy with my purchase. With the build quality update, Sigma has improved the quality of the internal glass too. Sigma is saying the QC of the new lenses is better too, time will tell.

I was drawn to this lens because I wanted a versatile lens for portrait and landscape work without the cost of the fixed 2.8 lenses. The extra 20 mm on the long end helps over the 17-50 mm offerings, and the f4 aperture is sufficient for beautiful bokeh with decent subject background separation.

This lens give me a portrait and landscape option, has fast enough auto focus to follow the kids in motion, is wide enough for an interesting perspective, has an effective OS system, beautiful color rendition, and wonderful build quality. I believe this lens is a wonderful replacement for all but the L lenses, strike a positive balance between cost and performance, and compliments the 70-200 mm fixed telephotos well.

I will update this review down the road, however if first impressions count for anything, this one deserves a second date :)

***NOTE: Original Review was written July 2013 - UPDATE September 2014 written at bottom of page****
****************************************************************************************************

This lens is very sleek in appearance and somewhat tightly made. It operates very smooth and mounts firmly into place. The visual appearance is a subjective thing, but I find this new design by Sigma to be quite appealing. Focus is silent, quick, and overall accurate as well, though not as accurate as other zooms I have used and especially my primes.

Alternative to these compliments, I have to say, unless you photograph center based subjects at less than infinity distances where borders do not matter, you will have some challenges. As noted by both photozone.de and lenstip.com, the wide end of this lens (17-24mm) is quite soft outside the center of images, 24-35 has some softness on the borders and stopping down beyond f5.6 stops does not alleviate the issue. If you use this lens for portrait or close focusing you will never see this issue.

In fact, for portrait and close focus, images are quite pleasing and this lens has very smooth, uniformed bokeh with no coma (coma being where an image has a doubling effect - edges of objects will have 2 or more edges instead of one). Overall, images are somewhat clean, but there are CA's to deal with at, again, the wide end of this zoom.

Here is a run down of the settings and performance of the lens.
=================================================
17-24mm: Very bad field curvature which yielded soft corners.

Update 1 (May 7 2013): I ended up returning my D7100 because I didn't really need to upgrade just yet. So now I'm using it on my trusty D90. The lens is still as sharp as ever. Autofocus is still fast. Having OS is a dream indoors. Since my D90 doesn't have spectacular ISO range before noise shows up, it's nice knowing I can go down to 1/40 or 1/30 and the image comes out tack sharp.

I also ended up getting another one of these for a friend and his copy is just as sharp.

If you're on a crop sensor, don't hesitate into looking at this lens. For 500 bucks, it's a steal. I don't know how Sigma can put such sharp glass, but they've done it.

Quick comparison of this lens against the Nikon 17-55mm f/2.8G ED-IF AF-S DX Nikkor Zoom Lens

Build: The 17-55 is a tank. Weather proofed, but also very heavy. On the other hand, this Sigma 17-70 contemporary is plastic, but also lighter and more compact. When I had the 17-55, I felt the weight on my arms and neck, but with this 17-70, I don't feel much of it.

Focus: The 17-55 is slightly faster. In a side by side comparison, there's not much to say except sometimes the Sigma will hesitate for about 1/4 a second, but the focus is always spot on afterwards.

Zoom Ring: The 17-55 is stiff as all hell when you go toward the wide end (~17-20) and the long end (~45-55). This is quite common with the 17-55. The 17-70 however is buttery smooth throughout the zoom range.

Sharpness: 17-70 beats the 17-55 hands down. Wide open, I had serious issues with the edges being soft and the corner soft.
