Overview A sophisticated and compact prime, the Sigma 30mm f/1.4 DC HSM Art is a versatile normal-length lens for APS-C-format Sigma SA-mount cameras. Featuring a bright f/1.4 maximum aperture, this lens excels in difficult lighting conditions and also affords increased control over depth of field for isolating subjects using selective focus. The optical design incorporates one aspherical element, which helps to reduce distortion and spherical aberrations in order to realize accurate subject rendering and high sharpness. A Super Multi-Layer Coating has also been applied to individual elements to suppress ghosting and flare for greater contrast when working in strong lighting conditions. Complementing the optical assets, this lens also features a Hyper Sonic Motor, along with a rear focusing system, that affords especially quick, quiet, and accurate autofocus performance, along with full-time manual focus override.
