In-demand range

The zoom lens covers three popular focal lengths typical of fast primes: 28 mm, 35 mm, and 45 mm, as well as the entire range in between. For high-quality performance at wide apertures, its design includes three aspherical and five low-dispersion glass elements. In total, the optical formula consists of 18 elements in 15 groups.

Internal focusing

Sigma 28-45mm f/1.8 Art HSM DC is equipped with internal zooming and focusing, which is especially important for video shooting — the lens maintains balance when changing focal length and focusing. Videographers will also appreciate the option to switch the aperture ring between clicked and smooth operation, and the minimal "breathing" makes the model even more convenient. Autofocus is driven by an HLA linear motor.

Beyond competition

The lens features an 11-blade aperture that creates expressive bokeh when shooting wide open. It is compatible with 82 mm circular filters and adds roughly 950 g to the camera’s weight. Sigma 28-45mm f/1.8 Art HSM DC effectively has no competitors among fast full-frame zooms, since the closest counterparts offer at best f/2.0.
