Actually, I've mostly given up on the separate focus button. I originally used that feature on the 5D because with action shots (like soccer games) I found that I had problems focusing on a fast moving subject and gave the camera a chance to focus on the wrong thing. But, at one of my grandson's soccer games in the spring I seriously missed focus on a few shots and decided to try putting focus back on the shutter button. I don't know if its me or the E-M1 vs the 5D but I was doing so much better focusing on fast moving kids that I left it that way and haven't changed back.

But in the particular 300mm shots I was talking about I was trying to shoot a great blue heron in our pond. I was surprised that he let me get within about 30 feet of him. But in that case I was using manual focus and 5X magnification. It's not bad and I think f/9 would have nailed it. And, no, I'm not afraid of diffraction at f/9. I was intent on getting the shot of the heron and the aperture is just where it was set and not set intelligently.

I just need more practice using these long lenses. Prior to the E-things I never regularly carried a lens longer than 200mm. Now I have 300 and 600mm equivalents. I've done a fair amount of event shooting here in the last couple of months but not much for myself. The 12-50 is the usual lens of choice.

I wish my results with the 75-300 were as good.  I don't think it's
the lens.  Either vibration (me) or focus or both.  Actually, maybe
insufficient DoF if I'm wavering back and forth.

This is a regular problem for me hand held, although I notice it much
more with CU/macro. My body has a tendency to move slightly forward and
backward, moving the plane of focus. I try to bracket, try to catch the
moment when my movement is at the right place or discipline myself to
get focus close, but then press through AF to shutter release in one
quick motion.

I'm much more prone to the last with long tele shots, which may be part
of why I have less trouble with them. I can see where your technique of
AF on a separate button could make it even more difficult.
