SP AF17-50mm F/2.8 XR Di II
LD Aspherical [IF]

Di II : for APS-C DSLRs

High speed, high performance, perfect light and image control

With its wide F/2.8 constant aperture, this superb high-speed wide-angle-to-medium-telephoto (26-78mm equivalent) zoom lets you create natural-looking pictures in almost any light, and shoot at faster shutter speeds too. One of the most compact and lightweight lenses in its class, its shallow depth of field at wide apertures allows you to create dramatic pictorial and portrait effects by softening background details so the subject looks more vibrant and three-dimensional.
