I have a Canon 90D with newly formatted 128 GB Scandisc SDXC card. With Canon 100-400 MKII, Shutter priority, Auto ISO, 1/2000 sec, high res JPEG, high speed continuous -- I get buffering after 4 to 6 pictures. DOes this sound normal with this high Megapixel camera? I'm used to a 7D Mk 11 under similar conditions where I can get at least a 10 second high speed burst before buffering. Thought I would seek real world experience from this group before checking with Canon.

What does the card say for write speed? When I google your "128 GB Scandisc SDXC card" description, I see miserable speeds of 80MB/sec up to 300MB/sec. You'd probably be better served with the price to performance around 170MB/sec.

Your EOS 7DII manual on page 151 gives a chart of file sizes and possible bursts. Large / fine JPEGs (20MP / 6.6MB) should achieve around 130 images in a burst.

Your EOS 90D manual on page 615 gives a similar chart of file sizes and possible bursts. Large / fine JPEGs (32MP / 11.1MB) should achieve around 57 images in a burst.

You can see, alas, the EOS 90D really is not the 'next step' of the 7-series EOS models.

Look at the card speed and see if that's an opportunity to improve the performance.

That sounds wierd on your 90D’s behavior. My 7D2 with the same lens will do about 30 raw shots before slowing down to a crawl. It does have 2 microprocessors compared to 1 in the 90D but still that doesn’t sound right.

You always give such great replies! Cheers!

As CHG_CANON mentioned, check the write speed to those cards and usually for a few dollars more you can get something in the 100mbps or slightly higher range. Was this an issue before these cards or did the problem manifest itself after the cards introduction?

Also check to ensure you are not shooting RAW unintentionally.

This doesn't sound right. I have had the 90D over 2 years now. Still learning with it. But when I set up to do this continuous shooting, I think holy crap seems to get 10 or more at a blink of an eye! Listen to what CHG_Canon suggest. When I got the camera the salesman and I talked alot about the SD cards. We put in camera a SDHC card 32gig. He also mentioned not to go to big of a card in size, 32 or 64 gig would be great.

So I'm thinking the card SDXC 128 gig could be the wrong card for Canon's operating system. And throwing it out of sync of their realm of shooting in the burst recording.
Just a thought to think about, maybe get an SDHC card and try.
Good Luck - Hope you find a solution. Bob

Sounds like a problem - somewhere - Try different cards - Maybe a NEW un-formatted card and make sure the card contacts are not being fouled in some way. If no difference call Canon !

Check if your using the HDR option.

That is what I thought too. I have the 80D and was disappointed in burst speed compared to the 7D I had previous. I changed the RAW setting to JPG and the camera became very capable of shooting burst speeds without slow buffering.

That is all related to the card! If you’re formatting the card in the camera, as previously suggested it’s the write speed of that card. I haven’t shot mine in 6 months since buying my R5 but when shooting Raw, Hi Speed continuous it took far longer to buffer out. Make sure to turn off the High ISO noise reduction reduction for optimum speed.
Contrary to another’s comment I found it to be a performance improvement over my 7D MKII for my shooting. It’s a very good camera capable of high speed burst shooting.

Oh no, now I’m in trouble because someone in Chicago will remind me that it’s “0ld” and ‘gasp’ “not mirrorless”🤫lol.

Will it directly affect "buffering" - probably not - but, it will affect your speed if you THINK you are not in HDR - making it seem like a buffering problem which, IMO is worth investigation.
