Sigma 50mm F1.4 DG HSM Art (Canon)

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's large diameter and floating system also help to correct for vignetting to ensure maintained peripheral brightness. This AF motor also permits full-time manual focusing control for refined precision by simply turning the focus ring at any time. This lens has been designed using an advanced optical structure to achieve both high resolution and sharpness along with an aesthetic out-of-focus quality for greater subject separation. A molded glass aspherical element corrects for sagittal coma flare and enables the full use of the fast f/1.4 maximum aperture with maintained sharpness and clarity. This design also works to minimize vignetting, color blur, and other distortions to help to produce natural and pleasing bokeh for selective focus and shallow depth of field techniques. This helps to ensure maintained image sharpness, clarity, and contrast regardless of focus point or aperture setting. This design also lends itself to minimizing vignetting throughout the aperture range for greater clarity and detail across the image frame. This floating system helps to realize a minimum focusing distance of 1.3' with a maximum magnification of 1:5.6. Additionally, this design also contributes to high detail rendering capabilities throughout the entire focusing range. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time. A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality. The included lens hood is fitted with a rubber connection for a secure fit.
