We posted earlier in April about Canon letting Sigma release APS-C lenses for its RF-S mount, and Sigma was planning to release six lenses initially. The Sigma 18-50mm F2.8 DC DN C RF was the first lens of the group to be released, and now the 10-18mm F2.8 DC DN Contemporary has become the second. The lens is already available to pre-order at B&H Photo for $599, and the shipment date is expected to be late September 2024.
Sigma 10-18mm F2.8 DC DN Contemporary RF Mount
When mounted to an APS-C sensor Canon RF mount camera such as the EOS R7 or the EOS R50, the Sigma provides an FF equivalent of 16-29mm thanks to 1.6x crop factor of the APS-C RF-S mount.

Canon already has a lens with same focal range -RF-S 10-18mm F4.5-6.3 IS STM- but as the name suggests, it is variable aperture and significantly slower than the Sigma. Here is a size comparison of these two lenses, you can also read detailed comparison of these two lenses here.

Press Release:
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.
