Sigma 50mm f/1.4 DG HSM Art Series Lens - Leica L-Mount

The technical details behind this lens

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. The Sigma 50mm f/1.4 DG HSM Art Series Lens - Leica L-Mount offers great optical performance and reliable construction. An ideal lens for portraiture, the bright f/1.4 maximum aperture pairs with a rounded nine-blade diaphragm to benefit selective focus and shallow depth of field imaging with smooth bokeh. It 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 deliver clarity and high image sharpness. The lens's large diameter and the floating system helps to correct vignetting to ensure maintained peripheral brightness. A Super Multi Coating has been applied to lens elements to reduce flare and ghosting for higher contrast and color fidelity.

Impressive Features and Optical Design

The integrated Hyper Sonic Motor (HSM) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM allows full-time manual focus control simply by rotating the focus ring at any given moment. Constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for higher precision and use in wide temperature variations. The nine-blade rounded diaphragm contributes to a smooth and pleasing bokeh quality. 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 one aspherical element that reduces distortion and spherical aberrations for improved sharpness and accurate rendering. The 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.
