Canon R6 II My R6 MKII keeps burst firing after I stop touching the shutter button.

[Chris Summers]

Not sure if anyone else has had this issue with their R6 MKII. I have had it happen a few times when shooting in the high speed burst and high speed burst + mode several times recently. I shoot a burst and stop firing and the camera keeps going for 10-15 frames or more.

Last night I was at a local rodeo and was shooting with the R6 MkII and my R7.
I was using the RF 70-200mm f/4 and the RF 100-500mm lenses and used both on the 2 different cameras.
I was in HS burst mode and also HS+
Electronic shutter on both
The 2 cameras are set up with similar button settings, I use BBF on one button with eye detection and one button with BBF for just the center area focus.
Several times with the R6 MKII I shot a burst and released my finger from the shutter button and the camera kept firing.
Never happened with the R7.
I have had this happen with this body also while shooting birds in flight.

I looked online and there were some posts in the Canon USA user's forum. I found several posts from last year, exact same thing happening. Lots of suggestions about doing a factory reset and then making button changes one at a time until the problem happens but that didn't seem to solve anyone's issue. Most of the OP's said they sent the camera to Canon and they either replaced the shutter mechanism or the mother board or some other component, it fixed it for some but not for others. Seems everyone who had the problem was shooting burst mode with E shutter and BBF so their might be a link.

Anyone else heard about this?

I’ve shot burst modes quite a bit and never had it happen to me on either my R6 or R6 mkII.

My first thought would be some kind of gunk or dirt in the shutter button causing it to stay held down.

It's the new "Post Capture" upgrade.

Never had this happen, but I've only used the pre-shooting function. Also, I think you can only use the e-shutter (up to 30fps) in raw burst.

Is the new "Post Capture" upgrade.

And if you don't want the upgrade, you might have to pay to have it removed.....if it is out of warranty.

OH MY GOD! DON’T GIVE THEM ANY IDEAS!

I've tried some of the suggestions like resetting and then adding in my custom settings one by one. Didn't seem to replicate it until after I was finished customizing the buttons. Shutter button isn't dirty or stuck so I am going to send it to CPS this week. I got it last May from B&H o it is still in warranty.

Chris, use your warranty while you can.
