This lens has a rounded 9 blades diaphragm which creates an attractive blur to the out of focus areas.

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 Canon digital or film SLR cameras. When used on Canon digital SLR cameras with the APS-C size sensor, the equivalent focal length of this lens will be 80mm, which makes it an excellent choice as a bright medium 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.

Designed to match the APS-C size image sensors of Nikon digital SLR cameras, the Sigma 30mm f/1.4 lens is an ideal choice for a wide range of applications, including snapshots, portraiture, indoor shooting, and landscape photography. The 30mm lens relies on two special-low-dispersion glass elements and a glass-mold aspherical lens. Combined, the construction details correct for all types of chromatic and color aberrations. Other features include a maximum aperture of f/1.4, a 62mm filter mount, and a one-year warranty.
