R5ii - Choice of SD card for slot 2 to avoid wake up problems

[AlanF]

I have had problems with my R5ii in slowly waking up when it's powered down (not turned off, just in eco settings). The EVF lights up immediately but there is no information on the screen and it is insensitive to clicking buttons, and it takes several seconds to be fully operational. No-one was able to help when I posted a question some time ago. The problem has now been solved (thanks to an AI search). There is a quirk of the R5ii to check the info on both cards when waking up. I had a high capacity CF Express in slot 1 and an 1800x Lexar V60 as an emergency overflow in 2, which is never used. The V60 is the problem - changing over to a Lexar 2000x V90 solved it. It's better to have only one card in the CF slot and nothing in slot 2 than having a slower one there. Despite the 1800x being 90% of 2000x, the V60 is not up to it. I never had this problem with the R5 with V60 cards.

That's annoying, all my backup SDs are V60 and the V90 ones are substantially more expensive. To be honest though I've always just used the CFE and not bothered putting the SD card in up to now. Couple of questions:

• Have you reported it to Canon? Might be fixable in firmware.
• How long is the delay on yours?
• What size of V60 were you using? I have 128GB ones, my hypothesis would be that a smaller card would take less time to check?
• Do you see the same delay if you only have the SD in there, or is it only if there is a CFE as well?

Will do a bit of testing on mine when I get chance and post the results.
