Sigma has formally announced the arrival of its 10-18mm F2.8 DC DN wideangle APS-C lens for Canon's RF mount.

It becomes the second APS-C lens and the second third-party lens that Canon has licensed to be let loose within the RF walled garden. As with Sigma's 18-50mm F2.8 DC DN, it significantly expands the options available to keen photographers looking to get the most out of models such as the R10 and R7.

The 10-18mm offers a field of view roughly equivalent to a 16-29mm lens on full frame, making it a useful wide-to-ultrawide option for Canon shooters who want a brighter aperture than Canon's own compact, $329 RF-S 10-18mm F4.5-6.3 IS.

As with the versions available for other mounts, the 10-18mm comprises 13 elements in 10 groups. This includes three fluorite-like 'F' low dispersion elements, one super low dispersion element and four aspherical lenses. It uses seven rounded diaphragm blades. It accepts 67mm filters.

At 270g (9.5oz) the Canon version is 10g heavier than the L-mount version in our database and 20g heavier than the X-mount variant. It's 72.2mm (2.8") wide and 62mm (2.4") long at its shortest, and extends slightly as you zoom out to the 10mm setting.

Sigma has said its four DC DN F1.4 primes, the 16mm, 23mm 30mm and 56mm lens, are expected to arrive for the RF mount next.

The lens will be available from "late September" 2024 at a recommended price of $659.

Pricing and availability of SIGMA 10-18mm F2.8 DC DN | Contemporary for Canon RF Mount announced

Ronkonkoma, NY – September 5, 2024 – SIGMA Corporation of America, the US subsidiary of SIGMA Corporation (CEO: Kazuto Yamaki. Headquarters: Asao-ku, Kawasaki-shi, Kanagawa, Japan) is pleased to announce the pricing and availability of the SIGMA 10-18mm F2.8 DC DN | Contemporary for the Canon EOS R camera system.

Originally announced in October 2023, this lens was first released concurrently for L-Mount, Sony E-mount and Fujifilm X Mount, and is now available for Canon RF Mount. This compact, versatile zoom is a perfect partner for the SIGMA 18-50mm F2.8 DC DN | Contemporary which was released for Canon RF Mount in June 2024. The new lens will be available through authorized retail partners in late September 2024 for a retail price of $659.

This is 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. Paired with the 18-50mm F2.8 DC DN | Contemporary, this duo of lenses covers a 16-80mm (35mm equivalent) range with the same bright F2.8 maximum aperture, with a combined weight of under 550g (19.5 oz.)

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 is not utilized by any other manufacturer, the hood has been made both thinner and smaller, which also contributes to the overall compactness of the lens.

The optical design of the lens delivers a short 11.6cm (4.6 in.) 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 autofocus system delivers swift, quiet AF during both still and video use.

Thanks to its high optical quality and compact size, the SIGMA 10-18mm F2.8 DC DN | Contemporary lens is an excellent choice for travelers, adventure photographers, vloggers, and family photographers who want great image quality when paired with today's leading lightweight crop-sensor cameras on multiple platforms.
