Using local and it is usually set on the center...so effectively it is spot.
Below is copied from one of my GIF posts...because I like this shooting/focus feature.
....see page 41 of Friedman's book regarding release priority. He says:
Using Release Priority, you can tell the camera to take the picture
RIGHT NOW, rather than waiting until the camera thinks the subject
is in focus. (In fact, this one’s so useful I’ll tell you where to find
that now: MENU►[camera icon] ►3► Priority setup►Release)
This is detailed starting on page 209.
This is a good feature IMHO. If the camera has failed at focusing (it happens) it is frustrating when you push the shutter and nothing happens. With the camera set as described, the shutter is released anyway. Yes, some photos are not in focus, but you keeping shooting and keep following though (panning) and, if it is long flight event, the camera will get it right sooner or later. In the past two days perhaps two of (what?) fifty++ flight events have failed to produce one acceptable photo because of "no focus."
