I don't use nor do I recommend anybody use super large to large SD or CF cards. Even if it can support a huge storage card it is a bad idea to keep all your photos on one card. The largest I use is 32gb and that is what I recommend you stick with, too. Of course I was in a place where losing photos was not an option but if you are just a snap shooter or hobbyist you may not care if you lose some shots.

For the EOS 7D Mark II I am sure that 128GB is the maximum supported card capacity for either CF or SD cards.

I just checked. My 7D II it's working perfect with a 256 SDXC UHS-I card. My card is Kingston Canvas Go Plus. <Third-party link removed per Community Guidelines> 

7D II can format the card (it see 232GB in the menu), it show 7800 available raw pics on INFO screen, and it write the pictures on the card. It can show the pictures and cycle them on the screen (so read also work perfect).

Elz… this is fantastic news!

On Wiki, the confirmed Canon specs stipulate 128GB to be the max.

Thanks a bunch for experimenting and informing on this!

I will source this same Kingston Card soon.

My 7D MKII also works with a 256GB SD card. have you tried with a 256GB CF Card?. The highest CF card i have is a 128GB. 🙄

When it’s hardly a great strain to keep a couple of other cards about yourself while shooting, I can’t see what is the push to stuff in the largest cards that are reported as apparently workable by other amateur users… If canon found that their design was RELIABLY able to handle, say, a total of 128gb capacity split between two card slots, why take chances with possibly unrepeatable lifetime-best images by exceeding factory spec?  Why not just stick to the spec issued by the maker but keep extra cards in your bag, your pocket?

Additionally - It’s often my experience that those who report data loss with devices like Cf and sd cards that their practice is to merely erase images, then reuse the card. Best practice is to reformat the card in the camera before reusing for photography. But people tend to think that because it’s been ok up till now, that means it’ll continue to be so. (False logic…) Cards ought to be reformatted after each time you take files off them. It refreshes the FAT, reorders the sectors where the data gets stored, Old logic? Yes. But also sound logic!

Plus. There’s some users happy to write a hefty cheque for the latest body or lens, but who hunt out the cheapest cards from ebay sellers.  Like the guy with a £50,000 fishing boat but uses cheap hooks and line then moans when some hefty beast straightens out those cheap hooks or snaps that bargain basement line. There’s places where economy is a fine idea, and others where it’s anything but.

That’s why I happily spring for quality brands for these vital components. Off topic? Maybe a bit. But not altogether.

"Off topic? Maybe a bit. But not altogether."

I'd say darn good advice. However, the thread is a year old and the OPsters are not likely here any longer to take advantage of it.

Obviously.

But. these things get accessed and read by others later on, looking for VALID related input. It’s for those that I submitted what I did. It’s an old enough set of principles, made ever-muddier by the idiotic over-labelling of cards even by leading brands with truly-multiple-squared alleged “standards” of write and read performance. For years I’ve been using mostly fast CF cards which by their very nature can be faster than SD in its variant daughter subtypes, Yet the CF card appears to be effectively dead now, because device manufacturers have for reasons that cannot include straightforward logic migrated to the hopelessly addled and confusing SD standard. My newly arrived R6 mk2 by Canon is onesuch. wading through the icons of speed standards has become a nonsensical madhouse of hoping that your choice was the best available. Marketing departments in makers of media must now be bigger guns than the tech developers who endlessly try to shoehorn ever bigger ratings into lesser designs because the guys upstairs want profit margins to be maximised to the nth degree. Buying the **bleep** things has become a bamboozling nightmare….

If I were the CEO of Canon/Nikon/ Sony, I’d push heavily for brand and type recommendations for each model according to the needs of each model. Such to be immune from back door handshake deals to agree to push a brand - due to kickbacks from the media maker.  Now THAT would truly be a step forward.

Even more off topic? Yes. But not irrelevant.
