Fast-Aperture Prime. The Sigma 35mm f/1.4 DG HSM Art for Sony E offers a fast f/1.4 aperture, which is ideal for low lighting conditions, narrow depth of field, and ample background separation for portraiture. A Hyper Sonic Motor system gives fast and accurate autofocus performance on either full-frame or crop-frame cameras. Using a APS-C sensor camera? You’ll have a focal length equivalent to 52.5mm.

Optics. A floating element maximizes close-focus performance, and the front of the barrel remains stationary regardless of focus distance. Two aspherical elements, Four Super Low-Dispersion elements, and one “F” Low-Dispersion element minimize chromatic aberrations, distortion, and vignetting.

Build. The 35mm A1’s build quality offers a substantial improvement over previous Sigma lenses.
