Canon has brought a whole range of its DSLMs up to date with a little firmware fireworks. Here are the February updates. The focus is on compatibility with the new APS-C zoom Canon RF-S55-210 mm F5-7.1 IS STM as well as the latest Speedlite EL-5 system flash unit, which uses Canon's new accessory shoe for the first time.
For the full-frame Canon EOS R6, the firmware update mainly brings the option to crop or resize images during FTP transfer.
