SIGMA has announced the release of two fast new zoom lenses, the 10-18mm F2.8 DC DN Contemporary for Canon RF Mount and the 28-105mm F2.8 DG DN Art lens. The 10-18mm F2.8 DC DN | Contemporary was originally announced in October 2023, first released concurrently for L-Mount, Sony E-mount and Fujifilm X Mount, and is now also available for Canon RF Mount. It is said to be the world’s smallest and lightest F2.8 zoom lens designed for APS-C format mirrorless systems. On the Canon system, the lens covers a 16-28.8mm (35mm equivalent) focal range, with a fast F2.8 constant aperture. The new lens will be available through authorized retail partners in late September 2024 for a retail price of $659US.

Meanwhile, the SIGMA 28-105mm F2.8 DG DN | Art zoom lens serves full-frame mirrorless camera systems in a compact, wide-angle to telephoto zoom lens with a fast constant aperture. Available for Sony E-mount and L-Mount, this lens covers focal lengths from 28mm to 105mm remaining at F2.8 through the entire range. Featuring HLA (High-response Linear Actuator) autofocus, and high optical performance, the SIGMA 28-105mm F2.8 DG DN | Art offers photographers and videographers a variety of premium standard zoom options depending on their personal style. Like the 24-70mm F2.8 DG DN II | Art and the 28-45mm F2.8 DG DN | Art, the new 28-105mm F2.8 includes a lockable aperture ring with click/declick function, as well as two AFL buttons and a zoom lock switch. Additionally, the dust- and splash-resistant design and water-and oil-repellant coating on the front element makes it suitable for shooting both stills and video in inclement weather.

A minimum focusing distance of 15.8 inches at all focal lengths, and maximum magnification ratio of 1:3.1 at the telephoto end add to the versatility of this zoom. This lens also features a rounded twelve-blade diaphragm, which helps to keep the large-aperture unit as small as possible. The weight has been kept under 2 pounds while achieving both a wide zoom range and an F2.8 aperture. The lens barrel near the mount is made of magnesium rather than aluminum, ensuring rigidity while reducing the weight of these parts alone by two-thirds. The lens will retail for $1,499US and will be available in late September 2024.
