Is anyone else experiencing this? The camera will become unresponsive with a black screen and viewfinder. Taking out and putting back the battery fixes this. It's been happening regularly, but I've been unable to reproduce this in a repeatable way and there is no error message. It froze 3 times today. One of the times I saw the info on the back screen was barely visible (viewfinder black). I looked the next time it froze and could not see this.

This has happened mostly when walking on uneven terrain but not sure if that is connected.

I tried to reproduce this in my home with 4 lenses and 3 different CFexpress cards, but could not get the camera to fail.

I am planning to send it in, but without a way for them to repeat the freeze I'm not sure what they will do.

I also had a glitch where the exposure compensation information disappeared (from both viewfinder and screen) from one of my C-settings. I tried to get it back without success. Luckily I had a fresh save of my settings and when loaded the exposure compensation information returned. I don't know if having this kind of problem could be in any way connected to my blackout problem.

Thanks for any suggestions or similar experiences.

No problems here yet with either firmware (knock on wood).

Does everybody update their firmware following instructions? No lens attached, and camera set to P Mode. I haven't had a single lock up with any of my bodies since doing that. Could be coincidence of course, but just saying...

I'll post if I experience any lock ups.

In my case no lens attached for sure but not in P mode. Bacause I have toggle it from the options.

I think I have done my firmware update in C3 mode.
Is it possible to reinstall?

I've never tried to reinstall the same firmware over. Maybe someone else has?

I have however rolled the firmware back to a previous release (on my R5), and then installed the new over that (again). There are specific steps and timing involved (which were posted on this forum a couple of years ago). Best of luck!

Thank you, really appreciated.



Seems a not supported procedure from Canon if I’m not wrong.



Maybe I will wait the new firmware.

It is possible to flash previous firmware versions and then the latest.

As for formal support id back R2. It not an obvious flow.

What I can say is we now have 3 x r52 which all came with 1.0.0 and updated to the latest.

We have used the bodies with the old r5 grip, our new 3rd party batteries and never had a stall.

Our grips are coming tomorrow according to royal mail and they will be used with the new batteries.

I really hope canon can find the source of the problem. If we can help (foc) send me a message and we would be very willing to support you.

Take care

Thank you very much, that’s very kind from you. As I mentioned, I’ve only had one err70 after about 100k shots, all using the electronic shutter. I prefer to wait and, if it happens again, I’ll send the camera back to Canon for a check-up. I’m from Italy, and I believe they are competent enough to resolve the issue if it exists.

Right. Definitely not supported! Perform at your own risk.

It's a new body, there should be more updates soon.

In the meantime, maybe try a different CFe card? Try shooting using only the eShutter?

Good luck to you!

Thank you for letting us know. Please get back to us if Canon provides any further information on the matter. In the meantime, I’ll continue to use mine and monitor how things progress.
 
Yes.

In my case, it gets stuck on the EVF, won't flip back to LCD...

As a systems engineer, I can tell you with my eyes closed, it's probably firmware. And yes, Canon should fix it. Have had to remove the battery 3-4 times now. Happens frequently after I shoot video, and then flip back to stills, in case you're curious.

I probably should open a case with Canon, instead of assuming they'll fix it.

Edit: Popped and email to Canon USA through the support portal, and registered my R5 Mark II. No confirmation other than the web page itself saying the email had been sent. I did get an email that my R5 Mark II was registered, though.

I just got my camera back from Canon. They replaced the circuit board. I'll start testing it out tomorrow. I assume it is fixed and will only report back if the problem recurs.

No way for me to know if other's problems are also bad circuit boards, but best of luck!

Canon told me to send in. Guess I will. Logic board defect? It’s plausible.
 
Well that was quick. Took it out this morning and within minutes I had an Error 70 message. Never had that before. And that was followed by 3 more freezes like I had before sending it in. This blows my confidence in Canon repair after they wrote they found the problem, replaced the circuit board and tested it.

Just to make sure we are all on the same page, when you unboxed the returned camera did you do anything at all with it before you started shooting?
 
Things to try:

Different power saving settings

Airplane mode

My R3 has had freeze issues on and off since I bought it over 2 years ago. Nothing too bad, but irritating. Since I turned airplane mode on it’s been golden (touches wood).

Wow - hopefully they will replace it! Canon has been so good in terms of service in the past, they need to sort this out. It’s very expensive to be having this many issues early on.
Between this unreliability, and the soft 4K60, and the IBIS issues, and noisy CLOG2 files, it’s a bit of a mess.

And $4650 with tax.

What’s the shutter count? They may have slipped you a “refurbished” replacement. That is, someone else’s return or ”repair” unit. That’s happened to me both with Canon, and other major brand names I’m not going to humiliate, but it’s common practice. Although I haven’t had to escalate with Canon, I have had to escalate with 2 other major electronics manufacturers as they kept sending me bad replacements, each with different problems. Eventually both companies sent me truly new replacements, both after either senior management escalation, or legal proceedings.

Now Canon, I’ve just sent back bad refurbs and gotten better ones. But, it could happen here.

4K60 just isn’t oversampled. You can shoot 8K raw though and do it yourself.

I haven’t had any problems with IBIS. In fact the opposite; the R5 II has the most effective IBIS to date.

Now do they have either logic board QC problems with a bad batch (happens to major electronics manufacturers, frequently I might add) or a firmware issue? Maybe.

My concern? If I send in my unit for repair, are they going to send me the OPs “refurbished” unit? Probably. Therein the trouble.

Do you have any idea how taxing shooting and storing and editing 8K RAW is? I’m guessing you don’t shoot it yourself.
Besides, it doesn’t do 60 frames per second.

Also you can get files with as much detail and sharpness with less noise, better DR etc on the Sonys while using files which are about 1/5 of the size (in terms of mb of storage). Think about that.

I just did a job where I was shooting the soft 4K60 for 15-32 second long clips off and on for two work days. After two days I had one terabyte of files to store.
That would have been 5 to 10 TB of storage if I were shooting 8K RAW - not to mention the overheating issues, etc.

@R2D2 and @Ephemeris

On Saturday, I spent around six hours in the field with the camera. Despite some heavy rain, I managed to capture a good number of photos and videos, including 2K at 240fps and 8K at 24fps—flawless performance throughout.

I had reset my camera to factory settings on Friday evening, which likely contributed to its smooth operation.

No disagreement here; I don’t process RAW video myself; same reasons. However it’s an option if you really want both 60P and oversampled footage.

My bigger gripe? Canon should include a HEVC 5.1 profile. There’s no reason they can’t. That’s a bigger difference for me personally.

Agree! Don't know why I can't do 8k@60p if I'm not using RAW.

It’s not possible to shoot 60P in raw
