SIGMA’s ultra-telephoto zoom for full-frame mirrorless cameras with L-Mount or Sony E-mount fittings offers a focal length range that is ideal for shooting wildlife, sports, and action. In addition, the minimum focus distance provides a maximum magnification of 1:2.8 for close-up photography. For outdoors use, the lens is environmentally sealed, and the front element has a water and oil repellent coating. The optical system contains special elements and other coatings which correct chromatic aberration and flare, while the built-in optical stabiliser offers approximately four stops of shake reduction. The optical quality is stunningly good, even at full aperture.
