1. Why Installing Firmware Update 1.1.2 Is Essential
In high-speed action, wedding, and event photography, card write reliability is the foundation of a professional workflow. When buffer data transfers from the camera’s internal memory buffer to dual SDXC UHS-II or CFexpress Type B cards, any interruption in the writing cycle can leave the camera busy or prevent files from closing correctly.
Firmware Version 1.1.2 specifically targets and corrects an edge-case bug where card recording processes could stall or fail to complete. By deploying this update, Canon ensures seamless file finalizing and card writing performance, eliminating write-time delays whether you are shooting continuous high-speed RAW bursts or recording long video clips.
