The Sigma 40mm f/1.4 DG HSM Art lens with Canon EF, Sony E, Nikon F and Sigma mounts is a member of Sigma's Art family characterized by its advanced optical construction and robust design. The combination of low-dispersion FLD and SLD elements helps to reduce chromatic aberrations, while a pair of aspherical elements, one of which is at the rear of the lens, further minimizes distortion and aberration. The optical design of 16 elements in 12 groups delivers consistent peripheral brightness and sharpness, even at a maximum aperture of f/1.4. A Super Multi coating has been applied to the lens elements to reduce flare and ghosting.
It has an efficient hypersonic motor that is fast, smooth and quiet. Nine rounded diaphragm blades contribute to a pleasing out-of-focus quality with shallow depth of field.
