For the Canon 7D mark ii, what are the maximum storage capacities that will work?

Max capacity CF CARD || Max capacity SD CARD

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).

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. 🙄

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.
