Reminder to update the firmware on your R6 Mark II camera...

[JFG]

Hello R6 Mark II owners,

I just updated my R6 Mark II with the latest firmware eosr62-v170 ver. 1.7.0 75.77mb  that was posted yesterday 5-13-2026, and want to remind all that updating your "Canon Camera's firmware" is one of the easiest ways to to make your R6 Mark II literally a better camera overnight.  When you update your firmware, you get better autofocus, better stability, new features, bug fixes, and improved lens compatibility.  All for free.  

Should you update your firmware when there is trouble with your R6 Mark II?  Yes, updating your firmware is one of the first things you should do when your canon R6 Mark II starts acting weird. 

Updating firmware won't help when there's  Physical damage (Shutter, IBIS, bent pins), Dirty lens contacts, Bad SD card and Wrong settings (like Servo AF disabled).  This are user-side or hardware issues, not firmware problems.

And before anyone asks... when you update your firmware, the safest way to do it is download the file, then open the file, and move the XXXX.FIR file to a formatted SD card into the main directory. The only reason it's "safer" than using the app is that you will not have to worry about losing wireless or bluetooth connection during the update.

The new R8 update was released s well. 

THEN...

Set your mode dial to "P", remove any lenses, and go to the yellow wrench menu and click on Firmware, and follow the on screen instructions. Be sure not to touch the camera until the update is complete. It seems most problems occur from people that did not follow these instructions.
