Still one thing to try...

Because it does focus...

Try to clean the contacts with something... if there is some kind of missconnection between the lens / adapter/ body , that can lead into this kind of behavior (or should we say missbehavior).

I don't have that 150mm lens, but sometimes my 12-60mm lens did same kind of things with ep3. Cleaning the contacts helped. Focusing is now slowish, but mostly accurate.

Good luck to you!
