Designed to Achieve High Optical Performance

Sigma 50mm F1.4 DG HSM | A Lens The Sigma Prime lens for | Canon EF, Nikon F (FX), Sigma SA Bayonet, Sony/Minolta Alpha 50mm f/1.4 DG HSM is a quick standard-length prime created to deliver high optical realization through the combination of triple Special Low Dispersion elements made of glass and a single aspherical element molded of glass. These elements, incorporated with a state-of-the-art optical structure, work to diminish flare, sagittal coma and chromatic aberrations as a way to deliver high image clarity and sharpness. The large diameter of the lens along with floating system also assist in ensuring maintained peripheral brightness and to improve for vignetting. . The lens elements also have Super Multi Coating applied to reduce ghosting and flare for greater contrast and color integrity.

An optimized autofocus algorithm, along with a Hyper Sonic autofocus Motor,delivers smooth, quiet, and quick AF performance that favors using this lens' in a wide array of situations. This autofocus motor also allows full-time manual focus control for refined accuracy as easy as turning the focus adjustment ring any time.

Sigma Global Vision - Art

    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.

Molded Glass Aspherical Element

    This lens has been designed using an advanced optical structure to achieve both high resolution and sharpness along with an aesthetic out-of-focus quality for greater subject separation. A molded glass aspherical element corrects for sagittal coma flare and enables full use of the fast f/1.4 maximum aperture with maintained sharpness and clarity. This design also works to minimize vignetting, color blur, and other distortions help to produce natural and pleasing bokeh for selective focus and shallow depth of field techniques. By reducing these aberrations, this lens is also well-suited to astrophotography or other situations with point-light sources due to its ability to suppress blur near the edges of the frame.

Special Low Dispersion Glass Elements

    Three SLD (Special Low Dispersion) glass elements have been incorporated within the lens design to correct for axial chromatic aberration throughout the entire focusing range. This helps to ensure maintained image sharpness, clarity, and contrast regardless of focus point or aperture setting.

Large Diameter Lens

    In designing the lens with a large 85.4mm diameter, and placing the widest elements within the front group, greater peripheral brightness is more easily attained when working with larger apertures. This design also lends itself to minimizing vignetting throughout the aperture range for greater clarity and detail across the image frame.

Super Multi-Layer Coating

    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.

Floating System

    By employing a floating system, the distance between glass elements is adjusted during focusing in order to limit the amount of lens movement required when shooting. This floating system helps to realize a minimum focusing distance of 1.3' with a maximum magnification of 1:5.6. Additionally, this design also contributes to high detail rendering capabilities throughout the entire focusing range.

Hyper Sonic AF Motor

    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.

Other Lens Features

  • A rounded nine-blade diaphragm helps to produce an attractive out-of-focus quality.
  • 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 outside of the lens barrel is also engraved with the year of production.
  • The bayonet mount is constructed from brass for ensured accuracy and durability.
  • The included lens hood is fitted with a rubber connection for a secure fit.
  • This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
