Sigma 24mm / 1.4 DG HSM Art (E)

The Sigma 24mm F1.4 DG HSM Art L-Mount is a wide and fast wide-angle lens that is part of the highly regarded Art line of Sigma's Global Vision series. The lens 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 at the rear of the lens, cancel out a variety of additional distortions and aberrations. The optical design of 15 elements in 11 groups is poised to deliver consistent peripheral clarity and sharpness, even when working at the bright f/1.4 maximum aperture. A Super Multi Coating has also been applied to lens elements to reduce lens flare and ghosting for better contrast and color fidelity. Complementing the optical performance is an equally capable Hyper Sonic motor, providing fast, smooth and virtually silent autofocus performance. This focus motor enables full-time manual focus at any time by rotating the focus ring for refined manual control. In addition, nine rounded aperture blades contribute to working with shallow depth of field techniques for an attractive out-of-focus quality.
