It is comparable in speed in focus when comparing focus speed on eos-m with adapter and ef lens to a7r with metabones ef adapter. eg 3seconds vs 2 seconds to focus from near 3\' to 8\' on sony a7r vs canon eosm respectively. [vs <1/2 second for 5diii]

I repeated the experiment with my 70-200 2.8 IS. <1/2s for 5diii, about 1s for EOSm, about 2s for a7r but only 50% of the time reaching focus.

In other words with ef lens and metabones adapter - only good for stills.

I don\'t have any sony e mounts to compare it to.
