Canon has released EOS R firmware 1.4.0.

Firmware Version 1.4.0 incorporates the following enhancement:

  • Enhances eye detection Auto Focus (AF) for improved face and eye recognition at greater distances.

  • Improved Auto Focus (AF) performance helps the camera to focus on and track smaller subjects.

  • Reduces lag time between the actual Auto Focus (AF) and the AF frame display for images in the viewfinder or on the LCD.

  • Fixes a phenomenon in which the AF frame size cannot be changed in the Servo AF setting.

  • Fixes PTP communication vulnerability.
