The Sigma 50 mm f/1.4 DG HSM A Standard Lens for Canon delivers incredible resolution and rendering performance, with a competitive price tag. Expressive photography As part of Sigma’s ‘Art Series’ product line, the 50 mm f/1.4 DG HSM A is designed to focus on advanced optical performance and superior artistic expression. Ideal for studio photography, landscapes, portraits and close-ups you can channel your inner artist and achieve high resolution with beautiful bokeh. The moulded glass aspherical lens elements effectively correct sagittal coma flare and colour distortion to give your photos beautiful soft rendering, without the blur, while maintaining a high level of resolution on the focus point. As a result, you can achieve a natural bokeh in portraits and indoor scenes. Enhanced peripheral brightness With a large 77 mm wide lens diameter, it would be easy to lose brightness in the peripheral areas of images. The 50 mm f/1.4 DG HSM A, however, secures brightness even at large apertures by positioning wide elements in the front group. HyperSonic Motor The HSM (HyperSonic Motor) ensures fast and quiet autofocus with full-time manual override. The enhanced AF algorithm gives you smoother autofocus which can be overridden anytime by rotating the focus ring to allow faster focus adjustment. Minimum focusing distance The DG HSM A incorporates an inner floating system that adjusts the distance between lens groups while focusing, reducing the amount of lens movement required. As a result, the lens achieves a minimum focusing distance of 40 cm, delivering high rendering performance throughout the focus range. Reduced flare and ghosting Super Multi-Layer Coating is used to reduce flare and ghosting. Combined with an optical design engineered to be resistant to strong incident light, the f/1.4 DG HSM A provides sharp, high contrast images even in backlit conditions. Redefine quality and take advantage of modern optical design and engineering, with the Sigma 50 mm f/1.4 DG HSM A Standard Lens for Canon.
