After installing firmware 1.5, I was having my R5 freeze regularly with animal eye autofocus mapped to back button focus. I installed firmware update 1.5.1 this weekend hoping it will fix the issue. I went out today to shooting some shore birds. My R5 locked up 3 times in a period of 1.5 hours of shooting, one of the three was was with error E70. In all three cases, turning the camera off/on fixed the issue; this is different from firmware 1.5 freezes, where I had to take out the battery to fix the freeze.
Please let me know if you need more information about the camera settings. I happy to share them.
Hey Canon support,
I captured the settings I use to duplicate this problem. I posted it here for your reference https://drive.google.com/drive/folders/17tHQ43gnQcgsxlu0uv7q-cgfKizXpGBP?usp=sharing
Please use C3 (Custom settings 3) with back button focus to test.
I'm happy to provide more information.
I'm quite nervous about installing this update. I'm not afraid it is going to damage the camera, but my fear is that there will be no improvement for all my freezing issues and that would be disappointing. I so want this camera to work properly. I hope others who have had the issue and decided to install 1.5.2 will give a report. I probably will go ahead and do the install and what is, is. If it is still a problem, my last resort will be to send it in to Canon to see if anything can be done.
I installed the update and went out and took a couple thousand images with the 100 to 500 with the configuration that was freezing on me earlier today... Using all manner of back button animal eye focus, electronic and manual shutter. Held electronic shutter a bunch of times till the buffer filled and NO FREEZE ups so fingers crossed this helped.
