Adjusting The Lens Flange Back - Panasonic HPX300 - Camcorder - 1080p Operating Instructions Manual

If images are not clearly focused at both telephoto and
wide-angle positions during zoom operations, adjust 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.
