The SIGMA 10-18mm F2.8 DC DN | Contemporary is the world’s smallest and lightest ultra-wide-angle zoom lens for APS-C cameras, covering an effective focal range of 15-27mm (35mm equivalent). Photographers can create expressive images anytime, anywhere with ultra-sharp optics, a bright F2.8 aperture, and a newly developed push-on petal-type lens hood. The lens features a unique aspherical element that reduces the lens’s overall size and enhances image quality.

This is the first SIGMA lens being announced and released concurrently for the L-Mount, Sony E-mount, and Fujifilm X-Mount.

This is the world’s smallest and lightest F2.8 zoom lens designed for APS-C format mirrorless systems at just 2.8 x 2.4 inches (72.2 x 62mm) and 9.2 ounces (260g). The lens covers a 15-27mm (35mm equivalent) focal range with a fast F2.8 constant aperture. Paired with the 18-50mm F2.8 DC DN | Contemporary, this duo of lenses covers a 15-75mm (35mm equivalent) range with the same bright F2.8 maximum aperture at a combined weight of under 19.5 ounces (550g).

The SIGMA 10-18mm F2.8 DC DN | Contemporary uses an aspherical concave lens with a large polarization ratio and high refractive index in the first group, reducing the number of elements in the first group and shortening the overall length. Additionally, a new push-on petal-type hood has been developed. Thanks to the new structure with a spring and lever, which any other manufacturer does not utilize, the hood has been made both thinner and smaller, contributing to the lens’s overall compactness.

The lens’s optical design delivers a short 4.6-inch (11.6cm) minimum focusing distance and a maximum magnification ratio of 1:4 at the wide end, allowing for close-up photography with pleasing background separation. The optical design also minimizes focus breathing, and the stepping motor delivers swift, quiet autofocus during still and video use.
