After years of waiting, SIGMA is finally releasing a selection of lenses for Canon RF Mount cameras. The Canon RF Mount was introduced in 2018, and since then, the range of EOS R cameras has become increasingly popular as DSLRs began to wane and mirrorless cameras became the new industry standard.
The Big News!
As of April 23, 2024, SIGMA is developing 6 APS-C format lenses under a license agreement with Canon, Inc. These lenses are:
- 18-50mm F2.8 DC DN | Contemporary
- 10-18mm F2.8 DC DN | Contemporary
- 16mm F1.4 DC DN | Contemporary
- 23mm F1.4 DC DN | Contemporary
- 30mm F1.4 DC DN | Contemporary
- 56mm F1.4 DC DN | Contemporary
The 18-50mm F2.8 DC DN | Contemporary will be available in July 2024, with the remaining models releasing at later dates, starting in Fall 2024.
The Features
SIGMA lenses for Canon RF Mount will offer exceptional compatibility with Canon EOS R cameras, although they are designed primarily for Canon’s popular crop-sensor camera bodies, such as the EOS R7, R10, R50 and R100 (available models as of April 2023).
Features of the SIGMA lenses for Canon RF Mount include:
Exclusive new design for mirrorless systems
Exclusive design with performance and functions that meet the expectations for mirrorless systems by leveraging the short flange back.
Autofocus tuned for each lens
Thanks to an autofocus drive control program tuned for each lens and high-speed data transmission, the lenses will offer high-speed autofocus.
Compatible with in-camera image stabilization
The lenses will be compatible with in-camera image stabilization. The camera senses the focal length of the lens and automatically optimizes image stabilization performance.
Aberration correction supported
The lenses will be fully compatible* with in-camera aberration correction, which includes corrections for peripheral illumination, chromatic aberrations and distortion. By matching corrections to the optical characteristics of the lens, this function takes image quality to an even higher level.
* Only when the camera is compatible.
Mount with dust and splash resistant structure
The lens mount incorporates rubber sealing to protect the mount from dust and water drops.
