In addition to the EOS R5 1.1 firmware update, Canon has also released firmware version 1.2 for the Canon 1D X Mark III. The new firmware improves a number of features and addresses a handful of bug fixes for Canon’s flagship DSLR.

Specifically, Canon says firmware version 1.2 improves face and eye recognition autofocus (AF) at greater distances, improves FTP connectivity during transmission and improves Wi-Fi connectivity when using the Canon EFT-E9 Wireless File Transmitter.

Canon has also improved the experience when using the Browser Remote and addressed a number of ‘phenomenons’ — AKA bugs — that can occur during viewfinder shooting when specific settings are selected. You can see a full list of the bug fixes in the changelog below.

Firmware version 1.2.0 for the Canon 1DX Mark III is available to download from Canon’s product page.
