Hey, just wanted to give you a heads up if you're having problems with error 20, which seems like many are having with the R5.
A client just got back to me asking for some missing photos and after reviewing my RAWs I noticed by file name difference that the camera didn't write 313 photos out of what should have been 2663.
I was having problems with error 20 during the photo shoot, and I'm guessing those files where in the buffer when I had to take the battery out and back in to be able to continue shooting and never made it into the cards after the power was cut-off. I'm not sure if the camera would continue writing to card after Error 20 if I wait a little before taking the battery out, though.
I hadn't noticed lost pictures because of this until now, but I had the camera sent in for warranty to Canon to fix Err20 a couple weeks ago and I'm still awaiting its return. It's a little scary shooting weddings with it now, but I hope fixing error 20 will prevent a future loss.
