The World's Brightest Full-Frame Zoom

Sigma introduces the Sony E-mount 28-45mm f/1.8 DG DN Art Lens, the world's first zoom lens for full-frame mirrorless cameras with an f/1.8 aperture throughout the entire zoom range. Featuring prime-like optical performance and video-friendly design and functionality, its wide-to-normal focal range means a lighter kit bag without surrendering image quality.

Design and Performance

The 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 Production

Designed 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.
