Simply test shots.
I noticed the late afternoon sun was looking nice for a few moments so I grabbed some test shots to watch the live view autofocus work. For most every subject I shot it at 100mm and then again at 400mm, so really it was 200mm-800mm, ranging from f/9 to f/32 i think, hand held with 1250 shutter, auto ISO capped at 6400. In full sun the combo did pretty well.
These are jpg from the camera, no post editing, no noise reduction, nothing. Take a look >> https://flic.kr/s/aHsmdq1nTR
