Versatile zoom for Sony E mirrorless

The Sigma 28-70mm F2.8 DG DN Contemporary lens covers wide-angle to short telephoto on full-frame Sony E mirrorless cameras. Its constant f/2.8 aperture delivers consistent exposure across the zoom range. The compact, lightweight body suits travel, event and everyday photography. Dust- and splash-proof construction adds reliability in challenging conditions.

Constant f/2.8 aperture across 28-70mm

The fixed maximum aperture of f/2.8 is maintained from 28mm to 70mm, enabling reliable low-light performance and depth-of-field control throughout the zoom range. The minimum aperture of f/22 provides ample stopping-down capability for bright conditions. Internal focusing keeps the lens length constant during operation, which benefits handling and filter use. Stepping motor AF delivers quiet, smooth focus for both stills and video.

Bright f/2.8 maximum aperture decides fit

The constant f/2.8 aperture is the single specification that determines whether this lens meets a photographer's need for consistent speed across the zoom range. Two FLD and two SLD elements combine with three aspherical elements to correct aberrations and distortion. Super Multi-Layer and Nano Porous coatings reduce flare and ghosting. A nine-blade rounded diaphragm produces smooth bokeh. Buyers who need wider angles, longer reach or a faster maximum aperture should consider other options.
