Easily focus on everything from static landscapes to playing children thanks to the powerful autofocus. A High-Response Linear Actuator autofocus system quickly and accurately shifts focus for accurate tracking of fast-moving subjects and rapid switching to a new subject. Thanks to the suppression of focus breathing, the lens is also suitable for professional video creation.
This lens features a powerful optical image stabilization system that compensates for 6.5 stops of camera shake at the wide end and 4.5 stops at the telephoto end. Powered by Sigma's OS2 algorithm, the stabilization system makes the lens more suitable for on-the-go handheld use, even when shooting in low light and at the long end of the zoom range.
Thanks to one FLD, three SLD, and four aspherical elements, the lens produces sharp final images with accurate colors and minimal distortion for a pleasant shooting experience throughout the entire zoom range, even wide open at f/2.8. A rounded 11-blade diaphragm produces beautiful bokeh with smooth focus falloff that wonderfully highlights the in-focus areas.
Continue using the lens in inclement weather conditions thanks to the dust- and splash-resistant construction, allowing you to continue photographing with comfort even as clouds roll in. Additionally, the front element features a water- and oil-repellent coating that makes it especially easy to clean.
