Excerpt: I use this lense with Canon 700D. I detected a slight front-focus and I think I may have to ask for front-focus correction. Besides that, there are other peculiarities. If you shoot with fully open aperture of f2,8 than only focal lengh 24-35mm preserves the desired sharpness in the focus area. If you want to shoot at focal lengh of 50mm - better to use aperture of f3.2 - 4.0, while with the focal lengh of 70mm - I would recommend aperture of f4.0 or smaller.
Pros: Good For Travelling, Lightweight, Rather Universal
Before you buy, read this. Great lens but too heavy for casual/enthusiast use

Summary: I have a Nikon D80 and wanted to upgrade my lens selection. This lens is beautifully made and is of pro/semi-pro quality. It is a good value for the money compared to the Nikon 24-70. It takes wonderful, sharp photos, especially at F3.5 range. BUT it is heavy. Too heavy to want to carry around at DIsney World all day in the heat of summer or anywhere else for that matter. The weight is not specific only to this brand.
Excerpt: As a travel photographer, I wanted to find a lens that was durable, relatively inexpensive, could cover most situations and still deliver high quality pictures. 24-70 is a good compromise but there are not many options on the market. <br /><br />The Sigma 24-70 f2.8 will deliver the best results when used with non-full frame cameras.
Excerpt: I bought this lens to go with my D700 and am reasonably happy with it overall. However, on a Christmas trip to the Santa Fe, NM, area I found that I frequently had to dismount/remount it to the camera, as it would occasionally stop metering or focusing when temperatures were in the 20s and 30s F. I also own a D300 with the Nikon 17-55 and have never had that problem in that kind of weather.
Pros: Constant aperture, Fast / accurate auto-focus, Sharp
Excerpt: I've been using this lens to capture city scenes (would not recommend for filming landscapes, portraits, nor interview subjects). A plus is that it's relatively lightweight and provides decent depth of field. A con is that you get a bit of vignette around the edges.
Excerpt: The lens is big and heavy with an 82mm objective so most filters I already have don't fit it. I have noticed in studio that if my meter reads a certain setting this lens is consistently one stop darker. Simply put, if my meter reads 1/125, f/8 at ISO 100 that setting is correct for ever other lens I own but if this lens is on the camera I have to roll up to ISO 200 to get the same exposure. Very frustrating. Should have spent the money for the Nikon lens.
Excerpt: This lens was sharp and had decent contrast. The only problem was with the focusing. One time it would back focus and the next time it would front focus. I used a focus chart numerous times always with different results. I have two other Sigma lenses that are excellent, suppose i just recieved a bad copy. Also the bokeh was a little on the harsh side. I sent mine back and ordered the Nikon.
Excerpt: I've been using this lens for a fortnight, and it has an annoying problem with the autofocus constantly focusing just in front of what is under the focus point in the camera. I've tried the autofocus across the zoom range and from F2.8 to F22 without much change. The areas that are in focus are perfectly sharp and the HSm is fast and quiet. But the consistently out of focus images really ruin this lens for me.
Pros: Consistent Output, Durable, Easily Interchangeable, Strong Construction
Excerpt: I have struggled with the decision Canon 24-70 L or Sigma 24-70 HSM ex, I have read every single review, on every single site. I decided to go with the Sigma. My wife insists that if I read a good Sigma review , that it was secretly written by the Sigma company and the same if it's a strong Canon review..I don't work for either company.
