What's your third issue?
File sync on cards.
Specifically: I have mine set up to write RAW to card 1, JPG to card 2. When I don't like a shot I hit the delete and it deletes only
the RAW (deletes only happen on the card selected for playback.) At the end of a shoot, if I did any in-camera trash collection, I have more .JPG shots than RAW shots. On import, the numbering sequence is all messed up and RAW15 may correspond to .JPG17...
Or I have to switch the playback card and delete the same image again.
I documented it and explained it in depth to Canon support. They agree it's an issue, albeit a fairly minor one, but it should be fixed, IMO.
