My kind of lens, the Sigma 23mm F1.4 DC DN Contemporary has an equivalent 35mm focal length, making it the obvious choice of the Sigma bunch for reportage and street photography, with its moderate wide-angle flattering enough for portraits and for when the surroundings are part of the story.
Mount: L-Mount, Sony E-mount, Fujifilm X Mount, Micro Four Thirds mount, Canon EF-M mount, Nikon Z mount, Canon RF Mount.
Canon kept is RF-mount closed to third parties for several years, meaning that only Canon-made lenses were available for its mirrorless cameras – and with Canon's lens-making efforts focused on its full-frame cameras, its crop-sensor cameras, like the EOS R10, and their users were mainly left out in the cold.
These lenses have been available for some time for Sony E-mount and for Sigma's L-mount (which is also used by Panasonic and Leica cameras), and some of the lens quartet are also made for Nikon Z-mount and Fujifilm X-mount, and other mounts too.
The 16mm F1.4 lens is the largest prime lens of the bunch, with the widest perspective, equivalent to 24mm.
