EOS R6 Mark II freezing frequently

Blackscarlet — Tue, 01 Apr 2025 12:17:30 GMT

I am a club and event photographer who works 6 nights a week. I have a canon R6 and I kept having freezing issues, where the camara becomes none responsive and i have to take the battery out before it works again. This occurs every night. Depending on the club, up to 8 times an event within a 1hr time frame. I sent the camera to be repaired under warranty and while it was gone I bought the 6d mk ii. Withing the first 25 mins of using it , it began to freeze up as well. unlike the r6 which had an error code , this just has a dark grey screen and yet again i have to remove battery to reset. I use all canon original gear. Is anyone else having same problem?

If this persists I will have to return the camera for a refund.

Update. i also got my 6d back and withing first day it started freezing again but this time not showing an error code.

Make sure that you have disabled Bluetooth and Wi-Fi. The GPS could be the cause issues, too, if it loses the satellite signal.

Hi Blackscarlet are you using adapted EF lenses on your R6 Mark II via the EF-RF adapter. Also are you using those same lenses on your 6D Mark II. A common link between the 2 cameras could be a faulty lens communication.

Do you any other lenses that you can test out on your R6 Mark II whether native or adapted EF glass. Do you have other EF lenses that you could test out on your 6D Mark II.

Hi i use 6 lens ef 24-70 f2.8L mk2, sigma 24mm 1.4, fisheye ef 8-14mm f4L, 50mm 1.8, ef 16-35 f4L, ef 85mm 1.4. This issue has happened with all these lens. i have just bought a new adaptor today will try it out and see what the results are like. Also i tried using only back screen last night. It still froze on me. Evf also takes about 3 seconds b4 it can adjust to the dark, way slower than the R6.

Are those same EF Mount lenses causing problems on your 6D Mark II also. Or only some of the above mentioned lenses only.

Update didn't use new adaptor because I wanted to lock on and making sure I tried as many of the lens as possible. same problem again occurs with the freezing up. I have slightly managed to narrow it down. Low light ie nearly pitch black areas in the club almost always makes the camera freeze up , when I try to focus . occasionally it freezes in mother areas, , this is with both Ef and RF lens. I will try new adaptor tomorrow , I am in the same club which I have the most problems in. I had a job an our before and the camera only froze once. the club which was darker it's froze about 9 times , generally in the same area of the club. it's so bad that when I look in the to evf to frame and focus, it's just pitch black. even though before raising it to my eye level I can see the camera working fine.

Wow. Such a wide spectrum of hardware with the same behavior.

Me - T6s Sandisk cards. Canon . Sigma APS-C lenses. Camera never froze. Owned for years. (sold it)

6D2, only one freeze in its entire lifetime. (still own it) Canon and Sigma EF lenses. I think it was the card. I may not have formatted it in camera before use. Usually shoot about 300 shots. + some video. GPS always on, mode 2 (on when camera is on, doesn't check for signal when power is off). Always use Sandisk Cards, Extreme Pro UHS-I. Rock solid performance.

Now R5 C. Arrived with FW 1.0.0.1, Upgraded to 1.0.1.1. Started using with Canon EF to RF adapter, Sigma 24~70 f2.8 Art. Worked perfect in photo mode. Quick, smooth and sharp. In Cinema mode, AF was sluggish. Wasn't hunting, it was just slow. Was talking with another user who has the Tamron 24~70 G2 and that lens didn't work at all in Cinema mode on his R5 C, but was perfect on his C300 mkII.

A week later I had a RF 24~70. Went out the following day. I was so blown away with the performance I came home and completed the trinity. Took a trip. Carried the RF 24~70 and adapted EF 70~300. It was great. Bonded with the camera 12 days straight. Didn't go crazy. I took about 1,000 photos and a few videos. Angelbird CF Type B and ProGrade v90 UHS-II. No card reader on the trip. I copied photos off the camera each night to a laptop. I shot about 300 images on the adapted Canon lens. No issues.

I believe that something in your settings, or hardware is causing the freezing. I've had one freeze on one body, last 3 body's and you are freezing on all of your body's. This is suspect. Hope the new adapter helps. Also try formatting your cards in camera. If you are swapping frequently between bodies without formatting funny stuff can happen.

A settings problem shouldn't be an issue as the camera should be designed to withstand whatever settings combination. I am hoping it's the adaptor, but it's worrying. I know 2 ppl in my field with my an r6 and 2 with r5. All with freezing issues. The R5 has happened only once, big difference is the owner uses back screen 95% of the time. The other R5 has freezing issues while taking pictures at a wedding. the R6 guys have freezing issues all the time, but the a predominantly using it for video.

Yeah Really hope its the adaptor because I am itching to buy a 28-70mm f2

Is the AF Assist Beam firing wether that be the orange AF Assist Beam from the camera body. Or are you using a speedlite's AF Assist Beam. IR AF Assist doesn't work on mirrorless. The speedlite should emit pre-fires/ Intermittent Flashes to assist the AF system. Even if the speedlite has a choice between IR and pre-fires/ Intermittent Flashes. The camera body overrides the speedlite AF Assist Beam emission method. The camera body also chooses where the AF Assist Beam comes from depending on ambient lighting.

Good morning,

I'm not disputing what's happening to you. It's real, I get it. Others have mentioned it as well. I just searched youtube for "R6 mkII freezing". I got zero hits. Google was different. There I got 4 hits. Yours was one of them. Consensus was Sandisk cards, and another guy saying it happens when he leaves the camera idle and when he returns, it "won't wake up". He called it a "blackout". Then said it did come back after a few seconds. Was his description. No one mentioned low lighting situations that I found. I searched the "fred miranda" forums and dpreview. Found one for the R6 mkII. The guy was using a Rokinon lens. I have one too, but no lock ups for me.

I have a room with blackout shades. I'll try shooting in it with a candle or at night. I've used my 6D2 in nearly pitch-black settings to a point where I thought no way is the camera going to capture this. Then to my amazement it did. There was some noise, but I was really surprised. You are the first user I've heard from with lock ups across multiple bodies EF/RF. We need for some users to try the new v1.7.0 FW (R6) I don't have one to test with.

Then leave their feedback:

My 6d and 5d MK4 are amazing in low lights. it is a weird one. The problem when ppl do low light reviews , it's always in controlled environment. In a club setting, you have , heat, moisture , rapid lights which go super bright on moment and and then nothing next moment, multicoloured lights shinning through haze machines (smoke). It an environment I never see camera reviews in. The closest would be at a wedding reception. I also doubt many people would have issues at this moment, the camera has only just arrived just a week ago and there are lots of delays. The old systems where bullet proof and have been refined to the last inch, so I am expecting a lot of teething problems. Early on , but not ones that actually make the camera unusable . I mean remember the overheating problems from jump.

Do you have any suggestions as to what SD to use? with the idle issue, I won't get that because of the nature of my job I am constantly shooting with about max of 2 mins break when I am moving to a different part of the club. Thanks for all the different info I am just worried that ppl are having the sam black out but for different reasons. might be what the camera auto defaults to if it just received an error.

So I have an update. I bought a new adapter for the camera and tried it out. Same issue occurred. Whats interesting is I have way less freezing issues when I use the back screen rather than the view finder. There is such a lag using it. It also feels like when I try to focus during the lag the camera completely freezes. So all that is left to do is try different brand of memory card.

Greetings,

Your last post is helpful. Hopefully others will also contribute. Have you upgraded to the v1.7.0 firmware (R6) yet?

I have always used Sandisk cards (every camera). The Extreme Pro UHS-II more recently. Always stellar.

I branched out with Angelbird and Prograde with my R5 C. They have also been stellar. The Angelbrid cards are CF Express B. They also make SDXC v90's UHS-II, but haven't used them yet. I have 2 Angelbird CF Type B and 4 Prograde v90's currently.

I had been using Sandisk cards for decades. I gambled on others and am now glad I did. Delkin cards are also recently popular, but I have no experience with them. I have no qualms about Prograde or Angelbird now.

Thank you for the suggestion. I am now ordering the prograde. Sadly my camera freezing issues got noticeably worse when I upgraded the firmware for the r6. The camera is also lest than a year Old. I will update with the memory card, Once it has arrived

Are you using full sized SD Cards or Micro SD Cards in an adapter. I wouldn't use Micro SD Cards in an adapter. They cause all kinds of issues in cameras.

Full size sd , I try not to skimp on my gear, so as to not get unwanted issues. I didn't even know you could use micro SD with the adapter.

Re: Canon R6 Mk II freezing frequently

deebatman316 — Sun, 11 Dec 2022 15:17:16 GMT

Most memory card issues in the forum are caused by the user using micro SD cards in an adapter. It's good to see that you're using the correct Full Sized SD cards to eliminate any problems.
