EOS R Keeps Freezing!!

hilliamonk — Fri, 26 Jul 2019 11:13:59 GMT

I purchased my EOS R back in October of 2018 from a local camera shop. Up until recently, my EOS R had been working perfectly. Recently, I started having an issue where my EOS R will freeze while using the camera. I have had the issue multiple times, and the only way I am able to get the camera to work again is by removing the battery and waiting a few seconds before inserting it again. When the camera is frozen, none of the buttons will work, and the on/off switch will not turn off the camera. The camera has the latest firmware installed (1.2.0). I am also using the lens that came with the camera (24-105 f/4 RF). The lens also has the latest firmware installed (2.0.0). I have tried using multiple batteries (Canon brand) as well as multiple memory cards, with no luck.

Did you reset the camera?

Are you using a micro card with adapter or a full size SD card?

Call Canon, it sounds like it needs service.

Seems to be a common issue with EOS R. One guy at Dpreview got this answer from Canon support:

"This could be a memory card issue if you are using the Ultra cards and shooting with HDR or Dual Pixel RAW enabled..."

He did have Ultra but he didn't use HDR or Dual Pixel Raw.

Another user:

"Used to have freezing issues until I upgraded to the newest firmware that came out a few months ago. Been solid since.

Edit: actually I changed to a Sony Tough card around the same time, when before I was using ultra cards, that could have been it too."

Just discovered the exact same problem by chance, kinda brand new body, original Canon batteries w/ battery grip, EF R 24-105, no matter what memory card. Showed up all the sudden, drove me nuts...

Checked and tried all kind of things, and hooray, seems I've found the cause: Disabled the automatic power off feature in the power saving options, problem seems to be gone.

Have indeed played around with settings in power saving options before problem came up, so this really seems to be linked.

It it were me having this issue I would immediately call Canon tech support. After getting the issue resolved with tech support and would then post the solution on here to help others.

Yep, me too, in Australia. latest firmware. Camera freezes every few shots - have to turn off and remove battery to get going again - when shooting models with active tracking [if that has anything to do with it?] Have contacted Canon and are awaiting a fix. What a nightmare!

Hi hilliamonk,

Thanks for checking in with us!

In addition to some of the other points mentioned on this thread, it might help to pay attention to the camera buffer. As you may have learned, when you're taking shots, the images don't go right to the card. They go to the camera's short-term memory, also known as the camera buffer.

When the camera buffer fills up, the camera will pause for a few seconds as the data is transferred to the card. At this point, you will not be able to fire any shots on the camera. You'll want to wait for the blinking to stop before you switch cards or batteries. Otherwise you risk the possibility of corrupted data.

You can tell how many shots are left in the buffer by referencing the number on the bottom right in the viewfinder. Once that number reaches zero, then you won't be able to fire any additional shots for a few seconds. If you are waiting for an important moment to photograph, be mindful of the shots remaining in the burst.

If problems persist, please elaborate on your camera settings, what you're shooting when the issue comes up, and which memory card and accessories you're using.

thanks - im a slow shooter, 1 shot / 5 sec so its not buffer - settings: firmware 1.6 - shooting with eye detect, continuous AF, single shooting, one shot, Sandisk Extreme Pro UHS-1 95 MB/s - no error msg but I didn't look inside the view finder - then I notice others who have this prob do see a error msg in view finder saying turn camera off and pull out battery....I'll try reformat card, then a different card perhaps...???

Camera worked flawless on firmware 1.2 but once I updated the freezing started. Anyone else can confirm they on higher firmware also?

I am having the problem with firmware 1.7. I am trying to isolate conditions when it happens. I do have a Sandisk extreme Ultra card 128. I do not believe it is a buffer issue. Yesterday it happened after one or two shots after pulling it from my camera bag. I didn't have to pull the battery. Simply turning it off/on did the trick but it happened again later on in the shoot. I did recently switch to the 128 card for it's faster speed but I might switch back to the Fuji card I was using and see if happens again. When it happens it is verry frustrating!

From whar you say, it almost certainly sounds like an issue with the SD card. Did you format it prior to first use?

Re: EOS R Keeps Freezing!!

Racer-X — Mon, 07 Sep 2020 20:13:49 GMT

Yes, I try and do a format in the camera before each shoot. Thanks

"I do have a Sandisk extreme Ultra card 128."

I am not aware of a Sandisk memory card with that name. Extreme Pro, Yes. Extreme Ultra, negative.

Ok, for clarity I went back and checked, it is the Sandisk Extreme card 128gb 150 MB/S card.

It sounds like it was a counterfeit card to me. Do not buy from that vendor again. Sometimes vendors buy merchandise for resale because it is cheap. They can be totally unaware of the fact that their merchandise is counterfeit.

Low level format the card. Not just format it. If you are unsure if it is fake or not, benchmark it in computer.
I have sent you a PM about testing software and write/read speed for that card.

any resolution to this? have an EOS R that if i take more than 4 shots in sequence it will freeze, its not a buffer issue as i shoot the pictures slowly. Its not a SD card issue, have two different cards and both formated at low level. Tried all the various options other have tried in this positing and no resolution.

I get ERR123 code, which is not listed as an error code.

Did have the camera serviced by Canon in the 1st 3months as the board failed. Any formal response from Canon on this issue? the camera is now 3 years old, so out of warranty status, is there any option to getting this fixed at a low cost?

Racer-X — Mon, 16 Aug 2021 23:20:40 GMT

No real resolution to my issue. It happens sporadically so I haven’t been able to lock down the trigger. Mine isn’t a card issue either as I have tried several cards. Pulling the battery out and re-inserting clears the freze-up. I have not gotten an error code though. I have not sent it to Canon as I was hopeful to lock down a repeated sequence that would cause it to lock up.

Hi Hillimonk

I bought this model 12-21-2023. Same problem. No resolve. Did get a new camera from canon? I unfortunately bought from unauthorized dealer. Returning it. They think they can fix it. Not!! What’s your resolve please?
