The 40mm F1.4 DG HSM Art is Sigma's first lens originally developed to meet the coveted angle of view and performance standards of a reference lens for the film industry. This lens features three FLD glass elements (F" Low Dispersion) and three SLD glass elements (Special Low Dispersion) to correct axial chromatic aberration and chromatic aberration in magnification. It is designed for exceptional sharpness at maximum aperture and is excellent for low-light shooting. With distortion of less than 1% and nearly nonexistent sagittal coma flare, this lens delivers consistent optical results that provide both 8K-compatible resolution and beautiful bokeh. The Sigma 40mm F1.4 DG HSM Art is available for Sigma, Nikon, Canon, and Sony E-Mount camera systems.
