Lens Description
The Sigma 18-50mm F2.8-4.5 DC OS HSM is a wide to short telephoto zoom designed for cameras with a APS-C (1.5X) sensor. This bright variable-aperture zoom covers a 18 to 50mm focal-range. It provides the same field of view as a 27-75mm lens on a Full-Frame camera. An optical Image Stabilization System built into this lens compensates for camera shake.
This 3X zoom lens focuses down to 30cm from the imaging plane, capturing subject with a maximum 0.24X magnification. The lens supports autofocus and features a switch to disengage AF for focusing manually. A Super-Sonic motor inside the lens delivers very fast and relatively quiet AF.
The lens weighs 395g.
This version of the lens has a Sigma S mount. It directly attaches and is fully compatible with all Sigma S mount cameras with APS-C (1.5X) or smaller sensors. Sigma also makes this lens for Canon EF, Nikon F, Pentax K and Sony A mounts.
