Canon has announced full details for two lenses on its full-frame mirrorless roadmap: the RF 15-35mm F2.8L IS USM and RF 24-70mm F2.8L IS USM. They both offer dust and weather resistance, a claimed 5 stops of optical image stabilization and Nano USM motors for fast and quiet autofocus.

Both lenses are around the same size but are heavier than their EF counterparts – the RF 15-35mm F2.8 weighs 840g and the 24-70mm F2.8 weighs 900g. Canon says that the RF 24-70 has substantially less focus breathing than the EF 24-70 F2.8L II. That's thanks to the system's shorter flange distance, which allows for placement of the lens' single focus element close to the sensor.

Both the 15-35 and 24-70 offer Dual Sensing IS, which uses information from the camera's sensor to judge camera shake more precisely. A combination of lens IS and in-camera digital IS can be used while shooting video.

The RF 15-35mm F2.8L IS USM and RF 24-70mm F2.8L IS USM are each priced at $2300 and will be available in late September.

Canon snuck a line into its press release saying that the amazingly small RF 70-200 F2.8L, a mockup of which is shown here, will be available in the second half of this year.

RF15-35mm F2.8 L IS USM and RF24-70mm F2.8 L IS USM Lenses Further Cement the Company’s Commitment to the EOS R Full-Frame Mirrorless Camera System

MELVILLE, N.Y., August 28, 2019 The time has come and the wave of momentous advancements in the world of the EOS R full-frame mirrorless camera system continues as Canon U.S.A., Inc., a leader in digital imaging solutions, today announced the introduction of the RF15-35mm F2.8 L IS USM and RF24-70mm F2.8 L IS USM lenses. With their large, bright F2.8 aperture, a zoom range that covers a wide range of shooting scenes and image stabilization (IS), as well as Nano USM – these lenses are sure to become workhorse lenses for professional and advanced amateur photographers.

“As the emergence of mirrorless cameras continue accelerating the market and with Canon’s deeply rooted heritage in optics, we are excited to expand the lens offerings and acquiesce the needs of EOS R users,” said Kazuto Ogawa, president and chief operating officer, Canon U.S.A., Inc. “The technical improvements and features within these new RF lenses are needed to drive the market forward.”

RF15-35mm F2.8 L IS USM

As Canon’s first F2.8 wide zoom lens equipped with IS for full-frame with a CIPA standard of five stops, the RF15-35mm F2.8 L IS USM lens is furnished with edge-to-edge sharpness throughout the zoom range to capture clear images with high image clarity from the center of the image throughout the entire focal range. Speaking of focal range, the RF15-35mm is an ultra wide range that allows for broader photographic expression with more emphasis on perspective. Other components include:

  • High Image quality has been achieved due to the large diameter mount and shorter back focus of the EOS R system.
  • Total size of the lens is equivalent to the existing EF lens, but allows for IS, wider field of view and the control ring indicative of the RF lenses.
  • Drip and dust resistant and ideal for landscape, architecture, nature, sports and portrait photography needs.

RF24-70mm F2.8 L IS USM

Created for a wide range of shooting scenarios from street scene snapshots to movie shooting, the RF24-70mm F2.8 L IS USM lens remains portable while equipped with IS. Other components include:

  • Equivalent to the size of the EF counterpart but with Image Stabilization.
  • High speed and high precision Nano USM motor for accurate, silent focus operation for stills and moving shooting.
  • Takes moving shooting into account with focus breathing suppression during manual focus operation, sensitivity setting during MF operation, usage of the focus ring is adjustable and customization of the control ring to assign aperture, shutter speed, ISO speed and exposure compensation as desired.

Free Firmware Update

In addition, a new, free downloadable firmware update will be released in late September for the EOS R system. Those interested can download the update for their respective system via the EOS R and EOS RP support pages. The update will improve three main functions:

  • Eye detection AF
  • AF frame display delay
  • Subject identification

The firmware update aims to add detection of the subject’s eye when the subject is at a distance, improve overall AF frame tracking for moving subjects, as well as improve initial subject recognition and start tracking when subjects are at a distance.

Pricing and Availability

The Canon RF15-35mm F2.8 L IS USM and RF24-70mm F2.8 L IS USM lenses are both scheduled to be available in late September 2019 for an estimated retail price of $2,299.00* each. To complete the trinity of F2.8 lenses, the RF70-200mm F2.8 L IS USM lens is scheduled to be shipping within the second half of 2019 – stay tuned! For additional information, please visit,
