EOS 7D Mark II & R6ii take forever to finish writing when shooting jpg

[DavidW55]

I had the same problem with my 7Dmkii, and now with my R6mkii as well.  When I shoot RAW, I have no problems.  I can shoot up to 40 fps, and rarely fill up the buffer.  But when I shoot jpg, and the card gets upwards of 1,000 images, after shooting, or when re-inserting the card, the red processing light will blink for literally 10 minutes or more. During this time, I can shoot more images without issue, and I can view the images, but I can't rate or tag any images. I get an error message saying it isn't available, and the red light continually blinks while I'm shooting or viewing.   I'm using a UHS-II V90 with a 300mb/s write speed, so it can't be that.

“ How does this solve the very same problem that I'm having with the R6ii? “

It sounded like you were having issues with your 7D2.  I see that the title of the post has changed. You added 6D2, but left 7D2.

Greetings,

Seems odd you are having the same issue with 2 cameras, and I've never experienced this behavior.  Might be because I don't store thousands of images on a card.  Maybe 1-2k but not more.  I shoot RAW+.JPG always.  I have shot .JPG only, but not thousands at a time that I can recall.  My SD cards are SanDisk and Prograde 128, 256, 512 UHS-II v90's.  I'm not discounting your use case, we all use our cameras differently.  I do not shoot professionally.  If my card access LED starting staying on as you describe (10 min) I'd start looking at my media and formatting process.  Even when shooting tons of video my card access LCD only stays on a few secs after closing the door.  Since what you described (sounds like) you are using known good media, correct formatting procedure and hygiene, I'd be inclined to contact Canon.  Let them tell you what's wrong and if necessary, I'd send my body and card to them for further evaluation.

I just don't see a good way for us to reproduce the issue and thus far you are the only person I've heard from reporting this behavior.

Also wanted to add that this is not something I've experienced on my T6s or 6D2, UHS-I cards ranging in size 32, 64 and 128GB.  I think you may want to seriously consider Canon Support.
