Using this lens for shooting my kids socccer games, as well as shooting around the zoo. Plan on traveling out West to the mountains next year. Great photos. Focus is fast enough, sharp pictures, and impressed with optic stabilizer feature. Really, really happy with the lens choice.

I use that lens to take animals pictures and wildlife in general. It is very sharpness with a fast auto focus.

I use it for wildlife photography. Everything works great but the controls are a bit industrial.

Bought this lens to possibly replace my Canon 100-400mm.The fact that it has twist zoom for this range inspired me to try it.I wanted to compare the image quality of this lens to Canon's.Well there is no comparison.Took both lenses and tried them shot for shot, side by side.I really wanted to like this lens,but couldn't have returned it any faster.Images are very soft and colors are off.Auto focusing drove me nuts as it wouldn't stay put.I'll keep the push pull zoom as I love the quality of images the Canon lens produces.

I bought this lens rather than the more expensive Canon 100-400. This lens is heavier, but I'm pleased with the job it does. Focusing is remarkably fast and accurate. The zoom ring is smooth. Stabilization is helpful, but handholding at 400 mm is still not going to produce crystal clear images. There are lots of nice touches: lock mechanism, padded case and straps, tripod ring. I've been using the lens on a monopod and ballhead, which works well enough for field shots of birds or wildlife when quick setup and mobility are necessary.

I am an avid amateur bird/wildlife photographer. I needed a long telephoto lens, and decided to try the Sigma 120-400 f/4.5-5.6 lens. I use it on a Canon Rebel T2i. I have had the lens only three days now, but have put it through a pretty good test of shots. the lens has exceeded my expectations. The clarity and sharpness are awesome, even throughout the range of focal distances. The OS feature is nice, but I feel a lens this size may require a tripod. I had no trouble getting it to focus on fast moving birds. I can't think of any negatives about this lens, and I highly endorse it.

I'v had this lens for about 6 monts now and it is great and sharp if you use it af F8 or above wich is alwayse in my case. I shoot with a friend that has the canon 100-400 and I totaly dislike the push-pull on canon. horible idea, pushes dust inside the camera and sensor. My pics comme out just as sharp as his for what i can see, exept wide open....never hapens. I shoot motly wild life and landscape. Sigma could have done a betther job on their tripod colar. I would like to be able to take the colar off with out taking the lens off the body. Shoot 90% on tripod with ot OS,

For the money, you can't do better than this lens (I wish I could afford a monster prime lens but I can't!). I bought it to shoot wildlife (birds mainly) and based on some quick testing at the feeders, this lens is outstanding. The focus is fast with my camera locking on targets quickly (not hunting).

A word of caution, it is very heavy weighing in at four pounds. I plan to use a tripod whenever I use this lens.

After reading reviews online about this lens, I was pretty sure that this lens would be a good one to add to my collection. The reviewers compared this to the out-of-date Canon 100-400mm lens and most of them had to force themselves to make a decision about which one was better (which is pretty good when comparing the price of the canon to that of the sigma). However, the pictures that I took with this lens were not nearly as clear as the ones that I took with my Canon 28-135mm. This was disappointing so I got a 100-400mm into my hands, took a few pictures and compared the two lenses. That is when I came to my conclusion - the lens is unpredictable. There are a few pictures that I have with my sigma that are far sharper than the Canon and others that are far softer than the Canon. This is probably a problem with the auto-focus system of the Sigma (Sigma is well known for their auto-focus problem). Also, I could have just gotten a lemon of a lens (those can make a huge difference and they very much exist, the favorite lens of a famous wildlife photographer is used as a paperweight for somebody else). Overall, good image quality, bad auto-focus system.

I use it with DSLR cameras.

Comments about Sigma 120-400mm f/4.5-5.6 DG OS HSM APO Autofocus Lens:

I bought this lens because i wanted a 400mm zoom and could not afford a comparable Canon product. After using it for about 6 months now on a Canon 7D i am reasonably satisfied with it. While its sharpness is very disappointing at f/4.5-5.6 it improves at f/8 and is very good at f/11 and smaller. Don,t plan to use it wide open unless you want a soft focus. The optical stablization works well.

After weighing through the canon offerings in the store they were just too pricey for my wallet. The gentleman behind the counter recommended this lens to me. I wanted to shoot the F1 in Canada this year and considering it zooms to 400 coupled with a 40D this was the lens for me. During the weekend I found the weight took a day to get used to, but attaching to a mono-pod helped greatly. The shoots I took were very clear and sharp at the higher f numbers (8 and above), however, thats not to say that at the lower f stops it was not sharp just that it was better higher up. Fast zoom and good tracking (following an F1 car at 170mph is by no means easy). Love this lens and I have many excellent shots from that weekend. Now I just need to get out and use it more! The case that comes with it is very sturdy and a nice extra.

I use it to photograph birds of prey any kind of bird or any other life form in flight. I also used it to photograph my grandkids in sports. I just like to see things up close and in detail and this lens lets me.

This lens is a replacement for the one that was stolen in Ecuador recently. I had used it for 3 months on my Canon 40D in Peru, the Amazon and the Galapagos and was more than thrilled. At half the price of the Canon 100-400 buying the Sigma glass is a no-brainer. Pan-zooming makes it easy to focus on flying birds and the OS feature means I didn't need a tripod although I did use a monopod in extreme low light situations. It is a great compliment to my Sigma 18-250. I am looking forward to many years of use on my new (insurance replacement) 50D.
