Agree, the A77II seemed very responsive even with my Mk1 lens. I could see that there were a lot of settings and I didn't have time to play with them all. I don't know what the focus mode was called but the local array of points which could be moved about the frame seemed very good. I didn't play with the tracking durations etc as I didnt want to wreck my mates settings.
Just not sure that's the way I want to go though. Time may tell...
All my Sony SLT gear gone. Still got my RX100 though.
