This review is subject to being updated as necessary. I've been using this lens more or less daily for over a month, mainly as a walk-around telephoto and for some wildlife (bird) photography using the Canon EF Extender 2X III (yes, it's compatible), always handheld. Birds, bugs, framed sky-scapes with planes passing by overhead - all these and more are fair targets for this lens. I am using a Canon T1i which is by no means a wildlife photographer's dream camera, so your mileage may vary (hopefully for the better) in some areas, e.g. metering, autofocus, and OS reliability. I have not used it for sports or situations where autofocus speed is critical, although I have been very happy in this respect.

My first impressions were that the lens was heavy, but coming immediately from the Sigma 120-400mm f/4.5-5.6, much of the operation felt perfectly familiar. The OS (optical stabilizer, equivalent of IS) still makes a bit of a clunk when it sets up or releases, although a bit meatier. Everything is bigger with this lens, and even when focusing you may feel the lens jump forward a bit in your hands. The box it came in, when you're looking at it sitting on a shelf after you've used the lens, starts looking about 2/3 as long as the lens (even if you rarely use the lens hood). One very nice improvement is the new finish. Gone are the nasty finishes of yore - the crinkle finish, and the matte finish (as seen on the 120-400mm) are forgotten and instead we have a new black metal body - despite there being at least four black materials, from a distance they all mesh together (you only notice the different ways in which the various black materials reflect light when looking very closely). The lens foot feels pleasantly rubbery.

This is my second Sigma 120-300 mm lens. Last year (sept 2010) I purchased a Sigma 120-300mm f/2.8 EX DG IF HSM APO Telephoto Zoom Lens for Canon SLR Cameras. That lens did not perform well at all. Purchased it for football (mainly night games), gave the lens 4/5 stars (see review on Amazon). I returned the lens since it would not work for my specific use, but otherwise the lens worked OK and didn't want to discourage others who may use it in other lighting situations.

A new version (the item above) came out with OS (and perhaps some other internal improvements?)(note I do not use IS/OS for football I've read where this lens is being touted as the ultimate sports lens. On paper that is true. I would love to have a 120-300mm and just carry 1 camera and lens vs. a fixed 300 or 400mm Canon with a zoom (70-200) on another camera.

Bad news is this model / copy was worse than the first / previous (model listed above). I tried this lens at 3 events and the auto focus is absolutely horrible in moderate light. I took over 1200 (over 400+ at each event) with horrible results. I use Servo focus and this lens simply will not focus. I even tried "one shot" focus and again it won't focus at all! Only shots that were partially focused with over 30 yards away. Missed many shots with the subject directly on the focus point for and extended period!! Lens works OK in sunlight but completely worthless in moderate light. Perhaps this is a defective unit, but based on my prior experience and the fact that it will work in sunlight I suspect it is just a poor design. Thus this time I'm giving it 2/5 stars.

When I switched back to my Canon 70-200 IS II the camera (5D II) and focus worked perfectly. So the Sigma lens is the problem.

I was looking for a relatively high magnification telephoto lens for a birding trip to Florida with a Photography Club. The leader and another member had the Sigma 120-300mm f2.8, another member had the Sigma 50-500mm f4-6.3, another had the Sigma 150-500 f5-6.3, another had a Canon 100-400mm f4.5-5.6, still another had a Canon fix magnification 400mm f4. I borrowed the Canon 400mm, rented the Sigma 50-500mm and the Sigma 120-300mm for weekend photo trips, and tried the Sigma 50-500mm, the Canon 100-400mm, and a Tamron 200-400mm f5.6 at various camera stores shooting a few test shots. In all cases I used a tripod. With the very pricey Sigma 120-300mm and a Sigma 2x, I could have a very flexible 240-600mm magnification range, greater magnification than any of the other lenses, and as fast or faster than any except the fixed magnification Canon 400mm f4. I also read many reviews on each of the lenses, many comparing two or more lenses. I don't have any special equipment to test the quality of the lens, I just look at the images on my computer screen. The price was the big obstacle, but I finally decided that I would not be happy with any telephoto lens other than the Sigma 120-300mm, and a 2x. I have owned the lens and 2x, which I use on a Canon 7D, for about 10 months. I shoot birds, and other animals, mostly at the nearby Shawnee National Forest and a few other state and national parks that are 15-50 miles from my home. I also have been attending several 150th Commemorative Reenactments of the Civil War. The lens is particularly great when I have to be at along distant from part of the field, but also need to rapidly respond to charging horses or men. I have averaged two photo shoots a month where I used the Sigma 120-300mm, mostly with the 2x.Read more ›
