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. The lens is also equipped with a Hyper Sonic Motor (HSM) that supports quiet, high-speed autofocus, but also turns off should you prefer full-time manual focusing. Other features include a maximum aperture of f/1.4, a 62mm filter mount, and a one-year warranty.
