Sigma 28-45mm f/1.8 Art Lens

This Sigma 28-45mm f/1.8 DG DN Art lens is built for full-frame Sony E-mount cameras and delivers a constant f/1.8 aperture across its zoom range. It suits photographers and videographers who need low-light performance and shallow depth of field without swapping primes. The bundle adds an 82mm filter kit, lens wrap, cleaning kit, cap tether and microfiber cloth for immediate protection and maintenance.

Constant f/1.8 Aperture

The defining specification is the constant f/1.8 maximum aperture maintained from 28mm to 45mm, a first for a full-frame zoom lens. This provides consistent exposure and depth-of-field control throughout the zoom range, allowing reliable low-light shooting and strong subject separation at any focal length. The optical design uses 18 elements in 15 groups, including five Special Low Dispersion and three aspherical elements to control aberrations and distortion.

Build Integration

The lens mounts directly to Sony E-mount bodies and uses an internal High-Response Linear Actuator for fast, quiet autofocus suited to both stills and video. Its 82mm front filter thread accepts the included filter kit without step-up rings. The constant f/1.8 aperture reduces the need to carry multiple fast primes, saving bag space and cutting lens changes in the field. It is not for shooters who need focal lengths wider than 28mm or longer than 45mm.
