Overview

The SIGMA 28-45mm F1.8 DG DN Art Lens was developed as a full-frame successor to the SIGMA 18-35mm F1.8 DC HSM Art (for APS-C DSLR cameras), which in 2013 became the first lens in the world to achieve F1.8 throughout the entire zoom range. While offering the convenience of a zoom, this new lens does not compromise on optical performance.

AT A GLANCEThe SIGMA 28-45mm F1.8 DG DN | Art delivers sharpness and clarity comparable to that of a prime lens throughout its entire zoom range. Also equipped with fast and precise AF and superior operability, this innovative optic turns a new page in the history of zoom lenses and their creative possibilities. It is a lens that will inspire full-frame film-makers, while bringing unparalleled versatility to stills photographersDesign and PerformanceThe lens features a total of 18 elements in 15 groups, with three aspherical and five Special Low Dispersion elements to minimize flare and ghosting and suppress various aberrations. This results in an optical performance that meets or exceeds that of other Sigma Art lenses, including the primes. Along with its 11-blade, rounded diaphragm, the design promotes sharpness and a large, smooth bokeh when used wide open.In addition to the f/1.8 maximum aperture, the lens also maintains an 11.9" minimum focusing distance across the entire zoom range. It achieves a maximum magnification ratio of 1:4 at its longest focal length, increasing depth of field and versatility in tight spaces. Video ProductionDesigned with video creation in mind, the lens' bright f/1.8 aperture and wide-to-normal zoom range make it a versatile tool ideal for single-shooter, run-and-gun setups. An internal zoom design maintains the overall length during use, making it easy to balance on gimbals. The design also suppresses focus breathing for smooth movement across the focal range. Sigma's high-speed, high-response linear actuator autofocus remains both quiet and accurate, while manual focusing is improved with click and lock mechanisms.
