Is Your Canon EOS R5 Mark II Autofocus Affected by the Latest Firmware?

Think I'll have to do a few experiments with my settings to see how far I can adjust them before the dreaded pull battery message appears. I suspect the viewfinder is the main culprit as most times I've had problems in the past was when the viewfinder had gone to sleep and failed to wake when I put it to my eye, despite pressing the AF button beforehand to re-activate the camera.

I've had my R5ii since April and frankly have had really no autofocus problems and I have an array of L lenses both EF and RF. I'm on firmware 1.0.3. My current opinion is that Canon has had more than enough time to correct this problem and have not released a solution. As I read forums, it appears that some Canon r5ii owners have had zero problems while many have had issues.

My current thought is that perhaps Canon multi sources chipsets and other components from an array of suppliers to reduce supply chain bottlenecks. If this is the case, there is a possibility that the issue is not firmware but perhaps the interaction of firmware with small component variations (in motherboards/etc).

If this is the case, Canon may not have a universal fix. If they ignore the problems, the cameras will gradually fall out of warranty and purchasers will be stuck with the problem and Canon will be off the hook for a costly fix.

I would say at a minimum all R5ii owners with a camera with problems should write Canon and ask for a rolling warranty extension until the problem is fixed or sadly group together and look into a class action against Canon for a defective product.

As a purchaser without a problem, I initially felt the issue was overblown. I've come to believe it is an inconsistent problem that Canon frankly doesn't know how to fix without a recall of the R5ii and that they do not want to deal with that cost.

I'm a long time Canon fan and have owned a QL1.7, FTb, EF FD camera, AE1, A1, F1 New, 20D, 30D, 40D 70Dii, 6D, 6Dii, R5 and R5ii. I'm sad to see Canon's lack of response or concern for these issues.

The new firmware version, 1.1.0, is now available on Canon's Hong Kong website. There are over half a dozen Err70 fixes included, but I didn't see anything specific to autofocus issues in Stills mode.

Nor anything about the battery issues...
I am very disappointed, I was expecting a real answer to real problems. This firmware is a bad joke! :mad:

My AF on my R5II still blocked sometimes and i need to change my zooming or recorded an focus point and return to it with a button, that the only solution i found, it happened when i did not touch the camera for a moment like 5 min and i want to shoot when i found something interesting, i already turn off the eco mode
I tested an other R5II with an other firmware 1.01 and it worked perfectly so i still it is a the firmware issue.

Send your R5ii to Canon to fix it.

Canon suggested I send my cameras to the factory, in Virginia, along with my RF 100-500mm, RF 400mm, and RF 600mm to have them synchronized to function properly. Imo, not a great idea for my situation. Either I send everything together in one huge doubled box or send one camera with one lens until all three cameras have been matched with the three lenses. The easiest thing Canon can do is solve the firmware issues.
