BulletPoint1 : The Nikon F 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. BulletPoint2 : 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. BulletPoint3 : 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. BulletPoint4 : 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 full use of the fast f/1.4 maximum aperture with maintained sharpness and clarity. BulletPoint5 : Three SLD (Special Low Dispersion) glass elements have been incorporated within the lens design to correct for axial chromatic aberration throughout the entire focusing range. This helps to ensure maintained image sharpness, clarity, and contrast regardless of focus point or aperture setting. BulletPoint6 : Lifetime Warranty BulletPoint7 : Compatible with all microSDHC host digital devices and supporting SDHC host products with the bundled SDHC adapter.
