This Sigma 50-150mm f/2.8 II APO EX DC Zoom Lens is designed exclusively for digital SLR cameras with APS-C size sensors, and its compact, lightweight body provides freedom of movement and versatility.

The minimum focusing distance of 100cm/39.4in. and the high-resolution power layout have improved the strength of the lens in close-up photography. This lens offers a maximum aperture of f/2.8 and its large depth of field offers greater freedom of creative expression.

Four SLD glass elements are used for maximum correction of chromatic aberrations. The super multi-layer lens coating reduces flare and ghosting and ensures sharp images throughout the entire zoom range. The lens design also incorporates an inner focusing and inner zooming system. As the overall length of the lens does not change during focusing and zooming, convenient handling is assured. The HSM (Hyper Sonic Motor) system allows quiet and high-speed auto focusing with full time manual focus override by simply rotating the focusing ring.
