When the lens is removed, install the mount cap to
protect the device.
If images are not clearly focused at both telephoto and
wide-angle positions during zoom operations, adjust the
flange back (distance from the lens mounting surface to
the image formation surface).
Once adjusted, the flange back does not need to be re-
adjusted as long as the same lens is mounted on the
camera.
Note
Please also refer to the lens instruction manual for
directions on adjustment and locations of individual lens
parts.

Mount the lens on the camera.
