Follow the procedure below if your camera is equipped with an Aa-
ton lens port.
If the port cap is on, remove it. Remove the lens stop knob by loose-
ning the single slotted or allen screw which secures it to the lens
lock ring.
Remove the lens lock ring by unscrewing it off the lens port ring.
Take a look at the lens port ring. Notice that there are three allen
head screws which lock the lens port ring to the lens holder, each
with an unoccupied hole alongside it. Also note that one of each
pair of holes will be marked with a red dot indicating Super16 posi-
tioning.
Remove the three allen screws and carefully lift off the lens port ring
and its accompanying shims and place on a clean surface with the
shim side face up. Take note of the screw holes from which the three
screws have been removed. Also note an unoccupied hole alongside
each.
Shift the lens port by refastening the lens port ring utilizing the se-
cond set of screw holes on both the lens port ring and the lens hol-
der. The clockwise-side holes on both are for standard 16 positio-
ning, the counter-clockwise holes are for Super16.
Carefully replace the lens port ring and its shims, and install the
three allen screws in the appropriate holes as detailed in the dia-
gram. Be sure not to damage the shims; take extra care to align their
cutouts around the holes to be used. Fasten the three screws, then
loosen each 1/2 a turn in preparation for fine centering.
• 5. Fine-Centering of the Lens Port.
There are two methods by which to set the exact centering of the
lens to the viewing screen. Both methods are equally acceptable.
Method 1 - via the Port Alignment Tool
The port alignment tool consists of the alignment jig and the cente-
ring rod.
Check that the screws of the lens port ring are loose enough that the
ring can move independently of the lens holder.
