Hi,
a new user ( pineyphotosnj ) raised the issue of focus after zoom in video.
I have taken a look and it seems you do not have the ability to fire a single AF Scan.
I don't have this camera, but I have compiled a test version to allow the assignment of a key
(set or half shoot) to fire a single scan.
If it is usefull, and tests out OK, then someone will need to ask the senior devs to apply it.
Compiled against trunk 889
Hope it works for you
