The Canon EF mount Sigma 50mm f/1.4 DG HSM Lens is a fast standard-length prime designed to achieve high optical performance through the incorporation of both three Special Low Dispersion glass elements and one molded glass aspherical element. These elements, coupled with an advanced optical design, work to minimize sagittal coma flare and chromatic aberrations in order to provide high image sharpness and clarity. The lens' large diameter and floating system also help to correct for vignetting to ensure maintained peripheral brightness. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity.
A Hyper Sonic AF Motor, along with an optimized AF algorithm, produces quiet, smooth, and fast autofocus performance that benefits this lens' use in a wide variety of situations. This AF motor also permits full-time manual focusing control for refined precision by simply turning the focus ring at any time.
The MC-11 Mount Converter enables the use of Sigma EF-mount lenses on Sony E-mount mirrorless camera bodies, and maintains full lens performance, including autofocus and auto-exposure, as well as in-camera correction technologies. An integrated LED can be used to display select Sigma lens compatibility with the adapted camera body, and the adapter also supports in-camera image stabilization. In order to maintain a high degree of image quality, the interior of the adapter is flocked to reduce reflections, and it also retains full Exif data to benefit post-production and file management.
Per Sigma, this Mount Converter/Lens Adapter is compatible with a select number of Sigma's own EF-mount lenses, and may or may not be suitable for use with other manufacturers' EF-mount lenses.
