This my second one of these lenses and I could not be happier with them. All of my sigma lenses are great and have never let me down.

This lens is a great compromise to the Canon EF L-series lens. The price is right and the images are great!

I just purchased another 24-70mm f/2.8 Sigma lens for my Canon 1Ds Mark II and this lens rocks. The auto focus is super fast paired with the 1Ds Mark II. WOW!!! I purchased this same lens for my older Nikon D-80 and it worked just as good but the auto focus wasn't as fast paired with Nikon. I normally shoot landscapes and don't use auto focus. This will come in handy when I start shooting fashion/swimwear shoots. This is a little on the heavy side but well worth the price. It will tend to search at times during low-light, but a simple switch to manual mode will fix that problam.

Great lens on 2 weddings so far. Its a Sigma, so we all know they are built like tanks. Heavy yes, but if you WANT PLASTIC.... go buy another brand ! This lens is nice for the money, worth what I paid. First lens was defective[...] Got this lens the day before my scheduled wedding. No real complaints, I probably will upgrade to the HSM model in time, I am not partial to this type of focus ring that you have to set a switch and kick the FR out of gear. All in all it is an excellent lens. Sharp IQ, pretty fast on the focus and SIGMA finish an weight.... love it !

I was in a pinch so I bought this lens on a whim and I have been trying to sell it since. Stay far away from this lens, it is fast at f/2.8 however I have not gotten any sharp images at any f stop. I wold not recommend this lens to anyone.

For the money you cannot beat this lens, it lets a lot of light in at f/2.8 and focus's really fast. I could not be happier

I've read before about Sigma lenses being stiff on the zoom, but I haven't experienced it with my 70-200mm... this lens is a bit stiff and will take a bit of getting used to.

I've had several Sigma lenses now and really like the quality build and clarity especially for the cost.

The one downfall to Sigma lenses in general is the new coating they are applying is not very durable. My 24-70 has not started peeling yet, but my 70-200 is peeling quite a bit around mount area.

I would recommend Sigma lenses to anyone looking for a quality lens with budget constraints...

If you're looking for the 24-70 f/2.8L, this isn't it. However, this is an outstanding alternative. I use this about 90% of the time with great results. This lens adjusts zoom range backwards from what Canon does. This took a little getting used to. My only real complaint about the lens is that at 24mm, the lens is extended all the way out. This interferes with the onboard (built-in) flash of EOS cameras. This is not the case with a hot shoe mounted flash.

Great alternative to Canon 24-70L. Works great on a 20D and 30D. On my ancient Canon D30, lens did not work well and was not pleased with focus or color. On the 20D and 30D, lens performs fantastically. Almost L-glass quality. Have heard that some copies of this lens are off-color or have focus problems. Most work as promised and represent a terrific value. If you have money, get an L-glass. If you don't...

I use the lens mostly on family and function events. You will easily get noticed because of the size of the lens. This is a sharp lens but I find it useful to postprossed it with my existing software from Cannon to make it even more sharp. Contrast and tone are excellent.

Comments about Sigma Sigma 24-70mm f/2.8 EX Aspherical DG DF AutoFocus Standard Zoom Lens with Hood for Canon EOS Cameras:

Bought this lens expecting it to be comparable with a Canon 24-70mm f/2.8L lens. However, I was very disappointed. Focusing is very slow and noisy. Zoom ring is very stiff. Zoom ring locks at end of wide angle and zoom. I have to press the shutter half-way to unlock it. Lens is very heavy. I ended up returning it and replacing it with a Canon 24-70mm f/2.8L lens. If you are in a tight budget then and you don't mind the bulkiness and stiffness of the zoom ring then this could be the lens for you. Other than that, I don't recommend it.

I purchased this lens to replace my Sigma 18-125, which itself is a small, light lens, but not terribly fast.

There are many reviews on the web stating that this 24-70 f/2.8 is a slow, noisy lens, which it is not. I found that it's very fast to focus, and on my EOS 30d, it's very accurate. The image quality is first rate, color, contrast and sharpness are superior to any lens I've used thus far. The lens is very solidly built, it's certaily not a light lens, but it's not exactly heavy either.

It makes a grand companion to my Sigma 70-200 f2.8.

A very nice lens, comparable to my L-series Canon Lenses. On a full-frame camera you'll see some vignetting when wide open, but for most digital cameras you would never notice this. Over-all, definitely worth the money, compares to much more expensive lenses!
