Focus Problem
 

I've noticed that when shoting in Manuel Focus mode that I still lose focus. It seems like the camera is still trying searching like in Auto Focus. It doesn't happen all the time but it happens enough to slow production down. Does anyone else have this problem?

You didn't indicate in your post if you meant manual focus on the lens or "M" mode at the main camera switch. If you are on green box mode, then the lens goes to A/F by default.

Sorry, Manual focus on the Lens... In (M) mode on the camera...

The lenses of past have suffered from focus drift when zooming in then out to the same position. A quick hit of the push a/f button gets you back in range. Many users who need perfect critical focus throughout the zoom range and back again alond with back focus adjustment, have used the 16x manual lens. The black one. It's a fix ... expensive one, but corrects for the servo nature of the white lens.

Just because the 16X is a true ZOOM, vs the white one which is a vari-focal lens.

Gerald, are you referring to the white 16x auto lens or the white 20x auto lens?
