Canon users with crop-sensor cameras, such as the EOS R7, have long been limited in their lens options. However, a recent announcement has changed the game, with Canon granting access to its RF-mount to third-party lens manufacturers Sigma and Tamron.
Sigma, known for its wide range of lenses for various camera systems, has announced six of its DC DN Contemporary crop-sensor lenses will be adapted for Canon’s RF-mount by 2024. This includes the highly regarded Sigma 10-18mm F2.8 DC DN, praised as an exceptional ultra-wide-angle lens for vlogging.
Tamron, another reputable lens manufacturer, is also joining the RF-mount league with its popular 11-20mm F2.8 F/2.8 Di III-A RXD lens. This move marks a significant milestone for both Sigma and Tamron, expanding their lens offerings to Canon’s RF-mount system.
Canon has been primarily focused on producing RF-mount lenses for its full-frame cameras, with limited options for crop-sensor RF-S models like the EOS R10. The announcement of Sigma and Tamron’s entry into the RF-S market is expected to bring a wider selection of lenses at potentially more affordable prices for Canon crop-sensor camera owners.
The existing Sigma lenses set for RF-mount adaptation include the Sigma 18-50mm F2.8 DC DN, expected in July 2024, and four F1.4 aperture prime ‘Contemporary’ lenses: the 16mm F1.4 DC DN, 23mm F1.4 DC DN, 30mm F1.4 DC DN, and 56mm F1.4 DC DN. Notably, Canon currently lacks fast aperture prime RF-S lenses, making Sigma’s contribution particularly valuable.
The addition of Sigma and Tamron to the RF-mount ecosystem is a significant development for Canon crop-sensor camera users. It opens the door to a wider range of lens options, providing greater flexibility and affordability for photographers and videographers who rely on these cameras.
