Yeah with number 1 there is no problems works fine. With number .2 its seems to be shifting even if the 'use pick focus region' is unchecked/disabled.
The reason like before other cameras(which has the 'use pick focus region' checked/enabled) seems to be affecting. But solution is the same, leaving unchecked in all cameras. Just letting you know anyway.
Thank you !!! Would you mind sending me a video please, while we taking a look here
