Sometimes when I am using autofocus with the Sony FDR-AX100 and a flat port on the Gates housing, autofocus doesn't work!
When looking at the clips after the dive, the subject can occupy 1/3 of the screen, and be nicely centered, and it is out of focus; the background is in focus even if it is relatively far away! The contrast seems to be sufficient; the camera apparently does not respond.
This seems to have happened after the latest firmware update to V3.0.
There seems to be more focus "hunting" underwater since the update. Topside, the problem does not seem to happen...
Anyone have any thoughts about this?
All help appreciated,
