SIGMA has expanded their Contemporary line by introducing the 16mm F1.4 DC DN and 23mm F1.4 DC DN lenses for Canon RF-mount APS-C mirrorless cameras. These lenses, previously available for Sony E, Micro Four Thirds, Leica L, FUJIFILM X, Nikon Z, and Canon EF-M mounts, are now open for preorder, providing Canon users with optically capable, fast-aperture prime options.
Canon has begun opening the RF lens mount to third-party manufacturers, allowing more options for content creators. Previously, only fully manual lenses without electronic contacts were available for the RF mount. Samyang and Viltrox had announced full-frame autofocus lenses for the RF mount, but those lenses have since been discontinued due to Canon’s enforcement of their intellectual property rights. Currently, third-party autofocus support is limited to APS-C cameras.
In November, we covered the announcement of these lenses, along with the 30mm f/1.4 DC DN and 56mm f/1.4 DC DN lenses. If you missed that coverage, you can catch up here.
