A wide and fast Nikon F-mount prime, the 24mm f/1.4 DG HSM Lens is a member of the highly regarded Art line of Sigma's Global Vision Series and is characterized by its advanced optical construction and robust physical design. The combination of three "F" Low Dispersion (FLD) elements and four Special Low Dispersion elements help to achieve a marked reduction in chromatic aberrations, while a pair of aspherical elements, with one positioned in the rear of the lens, minimize a variety of additional distortions and aberrations. The 15-element-in-11-group optical design is poised to deliver consistent peripheral brightness and sharpness, even when working at the bright f/1.4 maximum aperture. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity.
