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.

The memory card is my primary suspect.  Are you swapping the memory card between the cameras?  If so, then don’t. 

Do you format the memory card prior to first use?  If not, then do so.  Use the camera to format the card.  Select the “low level format “ option.  This card stays with this camera. 

Are you using the UHS-II card in the 7D2?  If so, then don’t do that.  The 7D2 was not designed to use UHS-II cards.  

Do you use micro-SD CARDS?  The cards that need an adapter?  If so, then stop and never use them again in your camera.  

Where do you buy your memory cards?  If you buy them on Amazon, then stop.  You should shop for camera cards and batteries elsewhere.  Lots of counterfeit stuff on Amazon and other online marketplaces that feature many sellers.  Go to a reputable camera dealer. 

Let me know your answers.

No, I only use one memory card for each respective camera

I always format before each session

No, I use a UHS-I in the 7Dii, but still has a write speed of 150 mb/s

Never. Ew!

Always from my camera store

No. My 7Dii has since retired.  But I always had the same problem when using it as I do now with the R6ii.  I shoot RAW 90% of the time, and never have this problem.  The odd time when Im shooting 5,000-10,000 images at an event, I'll switch to jpg, but then I run into this problem.

Your issues could be related to storing so many files on one card. 

[DavidW55]

I'll have over 4,000 imagess on the same card when I'm shooting RAW. No problems at all.

Thanks for your guesses though.

I was thinking about the thousands of photos you mentioned here. Personally, I would not risk having more than a couple thousand images on a single card.  Memory cards are cheaper than lost images.

You don't shoot high-speed sporting events do you?  I'm a professional sports photographer of over 10 years. With some events, I'm in the field shooting over 5,000 athletes, non-stop for over 8 hours straight.  For those events I have shot as many as 15,000 images in a full day, without having anytime to go back to my media station. For hockey, I'll shoot over 3,000 images in just one game.  If I'm doing a tournament, games will overlap, and I have no time to ingest from the cards.  As I said, when shooting RAW, there isn't a problem.  The only issue is when shooting jpg, and not being able to "tag" images will the card is reading, which will go on for 10, 15, and 20 minutes or more.  I can still shoot, record, and view images while this is happening.  I just have been unable to find a decent explanation as to why it's only a problem with jpg's and not RAWs.

No, I don’t shoot pro sports. But I do shoot amateur sports for hours on end. I might capture thousands of photos, too.  I don’t post examples because the athletes are minors.  

I don’t experience your issues. I use a 1D4 and a 7D2.  I carry spare cards in my pocket.  You made it clear that you don’t feel it’s a card issue.

I think you should consider it. Good luck.

If your 7D2 is retired, then this post makes little sense, to me.   Problem solved.

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