Canon releases mostly minor firmware updates for five cameras and its RF 50mm F1.2 lens

Canon has released a barrage of firmware updates for a number of its mirrorless cameras and a single RF lens, bringing new and improved features, as well as the usual bug fixes. None of the updates offer major improvements in autofocus or other areas, but they all take care of a few ‘phenomena’ and offer support for newer Canon lenses.

Canon RF 50mm F1.2 L USM

We’ll go ahead and get the most minor firmware update out of the way first. The Canon RF 50mm F1.2 L USM lens has received a version 1.0.5 firmware update that ‘Reduces image noise when performing high sensitivity shooting with the RF50mm F1.2 L USM lens attached to the EOS C70 camera.’ How exactly a firmware update for a lens addresses noise issues is a bit intriguing, but it never hurts to have the latest update anyway. You can download firmware version 1.0.5 for the Canon RF 50mm F1.2 L USM lens on Canon’s website.

Canon EOS R and RP

We’ve grouped these two updates together, because they offer the exact same changes, according to Canon’s changelog. Firmware version 1.6.0 for the EOS RP and firmware version 1.8.0 for the EOS R improves color balance when shooting with the Canon RF 50mm F1.8 STM lens and adds support for Canon’s newer RF 70–200mm F2.8 L IS USM and RF 100–500mm F4.5–7.1 L IS USM lenses. You can download firmware version 1.6.0 for the EOS RP and firmware version 1.8.0 for the EOS R on Canon’s respective product pages.

Canon EOS R5 and R6

As with the EOS RP and R firmware updates, the latest updates for Canon’s EOS R5 and R6 cameras are identical to one another based on the changelogs. Firmware version 1.2.0 for both cameras addresses the following changes and improvements:

  • When using high-speed or low-speed continuous shooting modes, in Drive Mode with [High Speed Display: OFF], the visibility of the subject within the frame has been improved when shooting moving objects.*
    *During continuous shooting black frames will be inserted between frames in the viewfinder and live view. This will improve the visibility of moving subjects in live view and in the viewfinder.
  • Adds the [Auto] setting to the [Viewfinder brightness] menu that will brighten and dim based on ambient light conditions.
  • Enables 2nd curtain shooting sync during radio transmission wireless flash shooting when the Speedlite EL-1 flash is attached to the camera.
  • Enables manual flash output (excluding high-speed sync and optical transmission wireless flash shooting) to be selected and set up to 1/8192 from the camera menu screen when the Speedlite EL-1 flash is attached to the camera.
  • Improves compatibility of HEIF images recorded in the camera with MIAF (Multi-Image Application Format) standards.
  • Adds support for AF and release during zoom operations for some RF and EF lenses.

You can download firmware version 1.2.0 for the EOS R5 and EOS R6 cameras on Canon’s respective product pages.

Canon 1D X Mark III

Lastly, Canon has updated its flagship DSLR, the EOS 1D X Mark III. Firmware version 1.3.0 addresses the following changes and improvements:

  • Enables 2nd curtain shooting sync during radio transmission wireless flash shooting when the Speedlite EL-1 flash is attached to the camera.
  • Enables manual flash output (excluding high-speed sync and optical transmission wireless flash shooting) to be selected and set up to 1/8192 from the camera menu screen when the Speedlite EL-1 flash is attached to the camera.
  • Improves compatibility of HEIF images recorded in the camera with MIAF (Multi-Image Application Format) standards.
  • Fixes the phenomenon that may result in the occurrence of time-out under certain conditions during FTP transfer.
