EOS R firmware update 1.4.0 enhances AF performance, and addresses PTP communications vulnerability issue.
Canon has issued another firmware update for the EOS R bringing in version 1.4.0. Key focus appears to be enhancing the performance of the AF system to make it faster to find faces, and improve eye recognition when the subject is smaller in the frame. It also fixes the PTP communication vulnerability too.
According to Canon this is what’s addressed with this firmware:
- 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.
This firmware update is for cameras equipped with firmware up to Version 1.3.0. If the camera’s firmware is already Version 1.4.0, this update is unnecessary.
It will take about 6 minutes to update the firmware. (So make sure you are using a full or nearly fully charged battery)
If you don’t have an EOS R, you can see if there’s a firmware update for your camera by checking my comprehensive EOS camera firmware update page.
My bug got fixed 🙂
This firmware fixes a bug with the operation of the M-Fn touch bar that I reported after the 1.2.0 firmware release.
I use the left tap section of the M-Fn touch bar to switch AF frame size when i’m using 1 point AF. Firmware 1.2.0 added the ability to use small or large AF frame size with servo AF. However the M-Fn touch bar didn’t change the AF frame size when the camera was set to servo and displayed a message – Function not available. Oddly you could change the AF frame size in the camera’s AF menu. Version 1.4.0 fixes this.
