I’m happy to report that steelsring adapter is able to drive the AF motor on canon 400mm DO mkii as if I attach it to my 1DX mkii. Af/focus is fast. Exif info correct.

Nice to know this. Would love to see some action shots. All these adapters are expensive so need to know more details before deciding which one to buy.
