The Sigma 50mm f/1.4 DG HSM Art. lens with Sigma, Canon EF, Sony A, Sony E and Nikon F 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 13 elements in 8 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.

The Sigma 50mm f/1.4 DG HSM Art is a lens with a fast maximum aperture of f/1.4, is ideal for working in low light conditions and also offers greater control over focus position when using shallow depth of field techniques. Designed with 13 elements in 8 groups; two of the elements are low F-dispersion (FLD) and three are special low dispersion (SLD), it also has aspherical elements to reduce chromatic and spherical aberrations and colour fringing for clarity and sharpness.
True to the concept of the ART line, this standard lens combines a large aperture with superior performance, offering excellent resolution that makes it ideal for the megapixel era on large sensors. It offers an angle of view similar to that of the human eye, giving photographers great creative freedom.
The Sigma 50mm f/1.4 features a brass mount combined with high-precision, rugged construction, and its treated surfaces and high strength contribute to the lens's exceptional durability. Both internally and externally. In addition, Sigma has reduced both vignetting and color fading in the front and rear of the focusing area.
Sagittal coma reduction in flare has also been achieved, making it a lens perfectly suited to work at high brightness across the entire image plane, even when shooting at maximum aperture.
It boasts fast, smooth and quiet autofocus performance thanks to the incorporation of an HSM motor that is complemented by an optimised AF algorithm to produce smoother focusing performance, and allows full-time manual focus control by simply turning the focus ring at any time. It is also equipped with a rounded nine-blade diaphragm that contributes to capturing images with an attractive bokeh effect.
