Canon has released firmware updates for the EOS R6 and EOS-1D X Mark III, plus has announced its intention for an update to the EOS R5 in due course. Canon states that these are in response to feedback from users and are designed to enhance video capture.
The new firmware for the EOS R6 (v1.4.0) and EOS-1D X Mark III (v1.5.0) brings Canon Log 3 (C-Log 3) to these cameras, a feature which has already been added to the EOS R5 (see firmware update v1.3.0, 30 March 2021). This feature expands the dynamic range and offers more colour space options to achieve rich, high-quality video that mirrors that of Hollywood standard cinema cameras. This logarithmic gamma curve also increases the compatibility of these models with cinema production workflows, making it easier to colour-match footage captured with Canon’s Cinema EOS Series cameras.
Simplified video workflows
Alongside the addition of C-Log 3, these firmware upgrades add dual card recording to all three cameras. You can now record the same video file – resolution, fps and codec – to both memory cards.
The firmware update for the EOS-1D X Mark III and EOS R5 also adds support for the new industry standard CFexpress VPG400 cards, which guarantees a minimum write speed of 400 MB per second for more reliable filming. This is essential when shooting in 8K or recording RAW footage.
Compatible with cinema products
The upcoming firmware for the EOS R5 will introduce compatibility to Canon’s CN-E18-80mm T4.4 L IS KAS S and CN-E70-200mm T4.4 L IS KAS S Cine servo zoom lenses. You will be able to control exposure, focus and zoom from the body, as well as start recording using the Record button on Canon Cine servo zoom lenses. This compatibility also extends to Canon’s EOS Utility and Camera Connect software.
Furthermore the firmware update for the EOS R5 will also make external full frame 8K ProRes RAW and 5K cropped ProRes RAW recording possible when connected to the Atomos Ninja V+ recorder, and 5K cropped ProRes RAW recording with the Atomos Ninja V recorder.
