With optical performance and functionality that deliver professional-quality results, all packed into a lightweight and compact body, this versatile, long-telephoto zoom is the perfect option for both dedicated field photography and casual shooting. Its focal range is well suited to shooting fast-action subjects such as sports, wildlife and motorsport, but thanks to its portable body that weighs in at less than 1.2kg, it's also ideal for telephoto landscapes and pet photography. It's even capable of macro-style close ups thanks to its maximum magnification ratio of 1:4.1. Optically the 100-400mm delivers outstanding sharpness right across the zoom range, with one FLD and four SLD elements that help to supress unwanted aberrations.

The lens is easily light enough for hand-holding, and Sigma's intelligent two-mode Optical Stabilizer helps reduce camera shake at slower shutter speeds. For those who prefer to use a tripod, a removable rubberised ring on the barrel allows a collar to be attached if desired (available separately). A range of other features including a focus limiter switch, custom modes, an AFL button, a lockable zoom ring and a dust- and splash-proof mount make the 100-400mm an extremely versatile option that can be used in a wide range of shooting conditions.
