Canon is Finally Letting Sigma and Tamron Make RF Mount Lenses
After years of the RF mount remaining “closed,” Sigma and Tamron have both finally broken through and will each release lenses for Canon’s mirrorless mount.
Canon has made good on its statement from earlier this year when it said that it was actively working to bring third-party lenses to RF mount. Conversations with Sigma and Tamron appear to have been conducted simultaneously, as both companies announced support for Canon RF at the same time.
Sigma’s entry into the RF mount comes in the form of six “Contemporary” lenses that are all currently available for other mirrorless camera mounts: the 18-50mm f/2.8 DC DN, the 10-18mm f/2.8 DC DN, the 16mm f/1.4 DC DN, 23mm f/1.4 DC DN, 30mm f/1.4 DC DN, and 56mm f/1.4 DC DN.
Tamron will also release optics for Canon RF mount starting with the 11-20mm F/2.8 Di III-A RXD (Model B060).
Sigma says that its lenses will be fully supported on Canon RF. Its lenses include a control algorithm for the autofocus drive and communication speed optimization, which Sigma says have been developed specifically for Canon RF Mount interchangeable lenses.
“In addition to realizing high-speed AF, the lens also supports AF-C (Continuous AF), in-camera aberration correction, and in-camera image stabilization. The mount is rubber-sealed to cater for use in a variety of environments,” Sigma says. The company did not provide a timeline for the release of the lenses.
