Always use the viewfinder for focusing." So, scale focusing appears to be out. Again, whether Olympus is trying to say that scale focusing is not as exact as viewfinder focusing so one should use the viewfinder, or that the adapting of OM lenses to 4/3 changes the scale distance wrt actual focal point is unclear. I have not tried scale focusing on my adapter non-OM lenses, so I can not speak to this point. One would think that the adapter would match the OM register distance and that would be that.
