Sigma 50mm f/1.4 DG HSM Art Series (Sigma SA) Lens

Key Features

• Super Multi-Layer Coating
• Three Special Low Dispersion Elements
• One Molded Glass Aspherical Element
• Aperture Range: f/1.4 to f/16
• Hyper Sonic AF Motor
• Remarkable Optical Performance
• Reliable Design

Being part of the Art line within Sigma's Global Vision series, this incredible lens' is designed to achieve remarkable optical performance and is perfectly suited for artistic and creative applications. Sigma 50mm f/1.4 DG HSM Art Series Lens - Sigma SA offers reliable construction and great optical performance. A Super Multi Coating has been applied to lens elements to reduce flare and ghosting for higher contrast and color fidelity. It 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 the floating system helps to correct vignetting to ensure maintained peripheral brightness. It features Hyper Sonic AF Motor, along with an optimized AF algorithm that produces quiet, smooth, and fast autofocus performance that benefits this Sigma lens's use in a wide variety of situations. This AF motor allows full-time manual focusing control for refined precision by simply turning the focus ring at any given moment.

Outstanding Features

The integrated Hyper Sonic Motor (HSM) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to deliver smoother focusing performance. Constructed using a Thermally Stable Composite material, along with traditional metals, for higher precision and use in wide temperature variations. The bayonet mount is constructed from brass to ensure durability and accuracy. A rounded nine-blade diaphragm helps to deliver a beautiful out-of-focus quality.

Great Optical Design

A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to delivering contrast-rich and color-neutral imagery, even in backlit conditions. It features three SLD (Special Low Dispersion) glass elements that have been incorporated within the lens design to correct for axial chromatic aberration throughout the entire focusing range.
