The following describes how to adjust the Back
Focus when using a Zoom Lens.
1) Lightly loosen up the screw fixing the Back
Focus Adjustment Ring using a screwdriver.
2) Image a vivid subject (with check patterns) at a
distance of 3 to 5 meters away and adjust the
zoom of the lens to TELE as far as it goes. Then
adjust the Focus Ring of the lens to obtain the
clearest image of the subject.
3) Adjust the zoom of the lens to WIDE as far as it goes.
Then turn the Back Focus Ring of the camera to
obtain the clearest image of the subject.
4) Repeat the number 2) and 3) steps two to three
times to exactly coincide the zoom focus from
TELE with that from WIDE.
5) Fasten the screw fixing the Back Focus
Adjustment Ring.
Note:
Turning the Back Focus Adjustment Ring to the “C” direction
beyond the adjustable range makes a sound at the limit.
