Earlier this year, Sigma announced plans to release several of its DC DN APS-C lenses for Canon's RF mount, making it one of the first third-party manufacturers to sell autofocus RF lenses under license.

Today, the company has announced pricing and availability for four of those lenses: the 16mm F1.4 DC DN, the 23mm F1.4 DC DN, the 30mm F1.4 DC DN and the 56mm F1.4 DC DN. On Canon's APS-C cameras, the lenses deliver full-frame equivalent focal lengths of 26mm, 37mm, 48mm, and 90mm, respectively.

These prime lenses join two Sigma zoom lenses announced for RF-mount earlier this year: the 10-18mm F2.8 DC DN, announced on October 5, and the 18-50mm F2.8 DC DN, which has been available for other lens mounts since 2021.

This brings the total number of Sigma APS-C lenses for RF-mount cameras to six, significantly increasing the number of dedicated APS-C lenses available for Canon's RF system. To date, Canon has released only a handful of slow RF-S zoom lenses, along with a dual fisheye lens for VR or spatial capture, though users can also use Canon's full-frame RF-mount lenses on its APS-C cameras.

With Sigma's newly minted RF-mount lenses in the mix, Canon's RF mount should become more attractive to APS-C shooters, especially those looking for dedicated APS-C lenses with faster apertures or primes.

The six lenses are already available for Sony E-mount, Fujifilm X-mount, and L-mount cameras. The 16mm F1.4 DC DN and 56mm F1.4 DC DN are also available for Z-mount and Micro Four Thirds.

The Canon versions of the 30mm and 56mm lenses will arrive first, launching on December 5. The 30mm F1.4 DC DN will retail for $369, and the 56mm F1.4 DC DN will retail for $529.

The 16mm and 23mm lenses will follow on January 23. The 16mm F1.4 DC DN will retail for $489, and the 23mm F1.4 DC DN will retail for $599.
