No, the Canon EOS R5 Mark II is not compatible with the Sony Tough CEA-G480T 480GB CFexpress Type A.
Canon R5 Mark II uses a Type B CFexpress slot. Sony Tough M is Type A — a smaller format that does not seat in a Type B slot. High-confusion pair: buyers see Sony + Canon and assume cross-compatibility.
