This focusing motor also enables full-time manual focus override at any time just by rotating the focus ring for refined manual control and focusing as close as 10.9″.A wide and fast Sony E-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.Sigma just announced a bunch of new E-Mount lenses that are looking to be seriously fast and of ultra high quality!Sigma is known for offering a more affordable option than Sony and/ or Zeiss, and the Art-series has been proven to be great quality optics for the money thus far.
Comprised of 15 elements in 11 groups, the lens design includes two “F” Low Dispersion (FLD) elements, five Special Low Dispersion (SLD) elements, and two aspherical elements to significantly reduce chromatic and spherical aberrations, as well as limit distortion for clean, sharp, and evenly illuminated imagery.
By matching corrections to the optical characteristics of the lens, this function takes image quality to an even higher level.
Native mount for a more rigid and stable feel Making the mount native to the lens makes possible a more rigid and stable feel to the lens.
A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity.
