Sigma's new 17-50mm
Compact, large-aperture zoomIn addition, the 17-50mm F2.8 EX DC OS HSM also offers one hybrid aspherical lens and two glass mold elements for excellent correction of distortion and astigmatism. It has Super Multi-Layer Coating to reduce flare and ghosting with superior peripheral brightness and Hyper Sonic Motor (HSM) to provide quiet and high-speed auto focus. The lens’ rounded, seven-blade diaphragm creates an attractive blur to out-of-focus areas and its inner focusing system eliminates front lens rotation, making the lens particularly suitable for use with the supplied petal-type lens hood and circular polarizing filters.
