The Sigma 50mm f/1.4 EX DG HSM Autofocus Lens is a standard lens that provides a large maximum aperture of f/1.4. It is the ideal prime lens for use with all Sigma digital or film SLR cameras. When used on the Sigma digital SLR camera (with the smaller APS-C size sensor), the equivalent focal length of this lens will be 85mm, which makes it an excellent choice as a bright short telephoto lens. Its large f/1.4 aperture allows for sharply defined contrasty images against a nicely blurred background. The lens offers superior peripheral brightness even at the maximum aperture, and corrects for possible flare.
The improved DG lens design corrects for various aberrations. This lens is specially coated to get the best color balance, while cutting down on ghosting caused by reflections from the digital image sensor. The lens provides the utmost correction against lateral chromatic aberration, which is a serious problem for digital SLR cameras.
This lens also incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF as well as full-time manual focus override.

Comments about Normal 50mm f/1.4 EX DG HSM Autofocus Lens for Sigma SLR Camera:
The lens reviews that I read for Canon and Nikon mounts were very favorable. In my use of the lens with a Sigma mount, I have found it to be very good. The build quality is very good. The pictures have been very good so far with nothing remarkable to report.
