Thanks guys.

 

@troporobo I was using 2 Keldan Luna 4X lights.

 

@SWink Crystal Blue is well run and the food is especially great.

Sometimes a decoy light can work. e.g. A very bright light pointing away from the scene, back over your shoulder.

...If this is equivalent to a +15 diopter the range is 49 to 63mm which is really small...


That wouldn't surprise me at all. You don't get that much magnification without some compromise. Users of that lens might be advised to take a weaker diopter as well.

Thanks. Are you using back button focus with 1-Area or Pinpoint?

I stopped doing it (AF) with the 12-50. Manual focus mode, and I use back-button focus to get close, and use the peaking and repositioning the camera as needed to fine tune.


By auto-focus I didn't mean continuous auto-focus, which hunts horribly (I've also just about given up using it). I mean temporary auto-focus at the beginning of a shot, which I do in manual focus mode by moving the rectangular yellow box to my subject and pressing the "AF/AE Lock" button. I guess I'm using 1-Area auto-focus. Wish I could make the yellow box smaller for more accuracy. Maybe I should be using Pinpoint auto-focus??? But trying it now I can't get the pinpoint near enough to the edges of the display. I badly need to go through the manual again I guess :scratch:

But even if that temporary auto-focus is more-or-less right, it's often not spot-on and I want to tweak it with a manual focus knob. Sometimes it's difficult to move the camera because of the situation, or you don't want to upset the subject or the seabed by shifting around.
 

...Even when I use manual focus i focus at the start of the scene and then don't touch it anymore for really small things...


For me also it's primarily for the start of a scene that I want manual focus, but also occasionally readjustments during a shot. I'd expect to trash that part of a shot where I readjust because of wobbles and errors, but not always if I got lucky of if there's important action at that moment.
