R5II Startup from Sleep

[Hector1970]

My R5 was always a little slow to restart after been unused for a few minutes.
It was a distinct lag maybe 1 second.
I just got an R5II and I'm surprised it has the same general issue.
I saw a thread from 2025 and it was around memory cards being the reason.
Is this really the case or is the camera just slow waking up.
This is generally not a huge issue. With the R5 I had the habit of pressing the focus button as I lifted it up to my eye.
I'm surprised I now need to do the same to the R5II.
I would have expected it to be more responive.
If its card related - why would that be the case. Why would the viewfinder not be ready if it was the card was slow waking up?
Does it happen with all mirrorless cameras.

My understanding is that the issue is with higher capacity memory cards. 256 GB is fast, 1 TB is slower. The camera probably has to ‘review’ the file structure in the card, determine free space, etc. Takes more time for larger cards.
