Sigma 50mm F1.4 DG HSM Art (L Mount)

The Leica L-mount 50mm f/1.4 DG HSM from Sigma is a normal-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. Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with a full-time manual focus override.  The prime normal-length lens is designed for full-frame Leica L-mount mirrorless cameras, however, it can also be used with APS-C models where it will provide a 75mm equivalent focal length. The prime normal-length lens is designed for full-frame Leica L-mount mirrorless cameras, however, it can also be used with APS-C models where it will provide a 75mm equivalent focal length. Three Special Low Dispersion (SLD) elements are featured in the optical design and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy. A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time. The bayonet mount is constructed from brass for ensured accuracy and durability. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
