Sigma 50mm f/1.4 Art DG HSM Lens for Sony E Mount

The Sigma 50mm f/1.4 DG HSMfor Sony E-mount is a highly efficient and adaptable prime lens, engineered to deliver exceptional optical quality. This is achieved through the integration of three Special Low Dispersion glass elements and one molded glass aspherical element. Together with a sophisticated optical design, these components effectively reduce sagittal coma flare and chromatic aberrations, resulting in images characterized by remarkable sharpness and clarity. The lens features a large diameter and a floating system that further mitigates vignetting, ensuring consistent brightness across the periphery. Additionally, a Super Multi Coating has been applied to the lens elements to minimize flare and ghosting, enhancing contrast and color accuracy. With its bright f/1.4 maximum aperture and a rounded nine-blade diaphragm, this lens is particularly well-suited for portrait photography, allowing for selective focus and shallow depth of field effects with pleasing bokeh.

In terms of functionality, the lens is equipped with a Hyper Sonic Motor, which facilitates rapid, smooth, and silent autofocus, while also allowing for full-time manual focus override. The construction employs Thermally Stable Composite material, ensuring durability across various environmental conditions, and the brass bayonet mount provides enhanced rigidity and precise mounting.

• 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 color fringing and chromatic aberrations for improved clarity and color 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 color-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.
