Anyway, from my own experience, I discovered that the weakest link in the camera/lens combo for birding and actions is the failure of the lens to acquire focus fast enough at high shutter speeds.

The mirrorless crowd insist that anything else can't do 101 things. Take eye focus, if you listen to them photography from the 1850s to 2010s couldn't produced a properly focused portrait.

It is certainly true with older lenses that screw drive, and some of the weaker in-lens motors can't shift the focusing elements in 1/12th second.  I think a lot of lenses date from a time where that wasn't a requirement.
