Performing the flangeback (backfocus) adjustment for the 16x Manual lens


Flange back adjustment of the lens

  1. Mount the camcorder on a tripod. Select an object 2-3 m away from the lens, or an object about the same distance away from the lens as your subject.
    - Use a subject with high contrast so it will be easy to tell when focus is achieved.
  2. Set the camcorder's mdoe dial to either Av or M modes.
  3. Turn the IRIS/SELECT dial to open the aperture.
  4. Zoom all the way in to full telephoto.
  5. Turn the focusing ring and focus on the object.
  6. Zoom all the way out to full wide angle.
  7. Fully release the flange back fixing screw on the lens (counterclockwise).
  8. Turn the flange back ring until you obtain correct focus.
    - The approximate position is where the flange back adjustment indicator is aligned with "F.B".
  9. Repeat steps 4) to 8) until you obtain the correct focus on ends.
  10. Tighten the flange back fixing screw with the ring set in proper position (clockwise).
