Position the camera body underneath the paper target with the lens
port facing up towards the target. Use a block of wood or a spacer of
sorts to position the camera so that the lens port is approximately
parallel to the ceiling.
Select the zoom lens that will be used most frequently with the ca-
mera; preferably the lens in your kit with the longest zoom ratio.
Mount the lens on the camera and tighten the lens lock ring mode-
rately.
Look through the viewfinder and set the zoom of the lens to its full
telephoto position. Focus the lens on the target and reposition the
camera body so that the center of the viewing screen cross-hair
exactly matches the center of the target.
Set the zoom to complete wide-angle position and notice that the
center of the target with relation to the viewing screen cross-hair will
track off in one direction. Without moving the camera steady, repo-
sition the lens and lens port ring until the target is centered. Using
an allen L wrench, carefully tighten the screws enough to secure the
lens port ring.
Set the zoom lens to telephoto position and check that the crosses
remain centered. If this is not the case, reposition the body, loosen
the screws slightly and repeat the above procedure. You will find
that, with each adjustment, you will come closer to the correct lens
centering.
When the cross on the target matches and holds its center through
the entire zoom range, firmly secure the screws. The target cross
should keep within the inside edges of the viewing screen cross-hair
to be considered in tolerance through the range.
• 6. Realigning the CCD Assist Target
The CCD assist needs to be repositioned and refocused to be pro-
perly aligned to the new optical center. See section 12.4 of the Ca-
mera Body chapter to proceed.
