Horrible on A1, A7riv, and a9

I will be returning the LA-FE1 firmware v2.  Just got it today and tested it with A1, A9, A7riv and performance was dismal with 24-70/2.8 AF-S (not vr) and 400mm/2.8 AF-S VR.  Performance with 24-70 was the "best" and would take anywhere from 1-3seconds to lock on to a static object.

Disappointed as I needed basic af functions but this is unusable.  Not sure how others are getting better results but this cannot even lock-on much less track.
