Sigma 50mm F1.4 DG HSM Art Lens with Canon EF mount.

Description

Overview

The Sigma 50mm f/1.4 DG HSM Art Lens with Canon EF-mount is the first entry into Sigma’s Art series of professional lenses. It has a bright f/1.4 maximum aperture, floating inner focusing system, and Hyper Sonic Motor (HSM) to provide quick and accurate control over the artistic effects achieved by the lens’ high-quality elements.

Features

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.

Hyper Sonic AF Motor

A Hyper Sonic AF Motor, along with an optimized AF algorithm, produces quiet, smooth, and fast autofocus performance that benefits this lens’ use in a wide variety of situations. This AF motor also permits full-time manual focusing control for refined precision by simply turning the focus ring at any time. Adjust focus using either autofocus (AF) or full-time manual focus, without having to switch camera modes or change settings – just flick the switch from AF to MF.

Design

For greater build quality and strength, all metallic parts and the new Thermally Stable Composite compound material (TSC), are housed internally. Its brass made bayonet mount has both high accuracy and durability, and a special treatment is applied to its surface giving it greater strength and making it highly resistant to long-term daily use.
