(More customer reviews)I'm a professional photographer[...] and until now, have never owned anything but Canon or Nikon lenses. For years I specialized in sports photography and the lenses I most often used were a 400 f:2.8 and a 600 f:4. I moved on to other fields of specialty and decided I didn't want to lug around that kind of weight and got rid of the big glass. Now, several years later, I decided I needed a long lens again, but in a decidedly smaller package. After trying an unnamed top manufacturer's 80~400 lens and being unhappy with the quality of the image, I dared to try Sigma's new 120~400. I ran the lens through the ringer and tested it under every situation I could think of and through it all, it has performed flawlessly! In fact, I was ready to accept a little less sharpness, so when I evaluated my results, I was thrilled. I highly recommend this lens and I have the utmost confidence in this beautiful package of glass.

The Sigma 120-400mm telephoto zoom lens covers a telephoto range of up to 400mm, letting you bring almost any subject close for short-perspective shots. The lens employs Sigma's original Optical Stabilizer (OS) function, which gives you access to shutter speeds approximately four stops slower without blurring the image. As a result, you can capture low-light, long-distance shots such as football plays, wildlife profiles, and landscape scenes without using a tripod for each photo. In addition, the lens incorporates a Hyper Sonic Motor (HSM) for quick, high-speed autofocusing, along with a rear focus system that guarantees optimum image quality throughout the entire zoom range. And photographers will love the three special low dispersion (SLD) glass elements, which correct for chromatic aberration, and the super multilayer lens coating, which reduces flare and ghosting. Other details include a minimum focusing distance of 59.1 inches, a maximum magnification ratio of 1:4.2, and support for optical 1.4x EX DG APO and 2x EX DG APO tele converters.
