Canon is preparing a new firmware update for both its flagship cameras. Firmware version 1.3.0 for the Canon EOS R1 and Canon EOS R5 Mark II is expected to arrive sometime in May 2026, according to multiple sources.
What to expect
While Canon has not published an official changelog, sources indicate the v1.3.0 update will bring autofocus improvements, new button binding options, and additional refinements across both camera systems.
Autofocus enhancements are the headline feature. Both the R1 and R5 Mark II use Canon’s Dual Pixel Intelligence AF system, and firmware updates have consistently improved subject detection and tracking performance since their launch. The v1.3.0 update is expected to extend AF capabilities in challenging lighting conditions and refine tracking for smaller subjects.
New button customizations would address a frequent request from professional users. Additional assignable functions and more flexible control configurations would allow photographers to tailor the camera’s ergonomics more precisely to their shooting style.
Timeline
In late April, a source had been told to “prepare” for an upcoming firmware release. The phrase was used approximately one month before the expected launch, which would place the release window in mid-to-late May 2026.
The timing makes strategic sense. With the Canon EOS R6 V announcement expected on May 13, Canon may bundle a broader ecosystem update across its lineup. Firmware updates for the R1 and R5 Mark II would keep the flagship bodies competitive and demonstrate continued software investment after purchase.
What is missing
Canon has not confirmed specific firmware features, and the changelog has not been published. The exact release date within May is also unconfirmed. Firmware updates of this scale are typically released as free downloads through Canon’s website and the Canon Camera Connect app.
