I've had the back focus on the Fujinon XS16x5.8A-XB8 - 1/2" lens (that is packaged with the Sony PMW-320K), go out on me twice now. The first time I just did the back focus adjustment as per the manual, and it worked great. However, the back focus has gone off again.
In the manual it says to only adjust the back focus once after mounting
or changing the lens. Can't I just back focus it again? Or do I have to remove and then re attach the lens first?
