Olympus cameras got outpaced by old folk about to kick the bucket, imagine that.
Actually the problem isn't just with the movements. As soon as he turn his back to the camera, it also shat in the bed.

Olympus just isn't as reliable, just deal with the fact that you need an manual focus puller to assist you.
