High Performance Prime Lens

The Sony E-mount 50mm f/1.4 DG HSM from Sigma is a fast and versatile normal-length prime lens designed to deliver superior optical performance. It features three Special Low Dispersion glass elements and one molded glass aspherical element, plus an advanced optical design, to minimise sagittal coma flare and chromatic aberrations. The large diameter and floating system also help to reduce vignetting and maintain peripheral brightness. A Super Multi Coating has been applied to lens elements to reduce flare and ghosting, for higher contrast and colour fidelity. With a bright f/1.4 maximum aperture and a rounded nine-blade diaphragm, this lens is ideal for portraiture, providing selective focus and shallow depth of field imaging with smooth bokeh.

Complementing the imaging capabilities, the lens sports a Hyper Sonic Motor to produce quick, smooth, and quiet autofocus performance with full-time manual focus override. The physical design utilizes Thermally Stable Composite material for durability in a wide range of environments, and a brass bayonet mount also offers rigidity and mounting precision.

• As part of the Art line within Sigma's Global Vision series, this lens is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
• Prime normal-length lens is designed for full-frame Sony E-mount mirrorless cameras, however it can also be used with APS-C models where it will provide a 75mm equivalent focal length.
• Bright f/1.4 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
• Three Special Low Dispersion (SLD) elements are featured in the optical design, and help to reduce Colour fringing and chromatic aberrations for improved clarity and Colour accuracy.
• One aspherical element reduces distortion and spherical aberrations for improved sharpness and accurate rendering.
• 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 Colour-neutral imagery, even in backlit conditions.
• Nine-blade rounded diaphragm contributes to a smooth and pleasing bokeh quality.
• The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.
• The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations.
• 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.
