The Sigma 30mm f/1.4 DC HSM Art is a versatile normal-length lens for APS-C-format Canon EF-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. Normal-length prime is designed for APS-C-format Canon EF-mount cameras and provides a 48mm equivalent focal length. One aspherical element is used to help limit distortion and spherical aberrations and also contributes to greater overall sharpness and accurate rendering. Integrated HSM (Hyper Sonic Motor), along with a rear focus system, realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.
