window, make the adjustment by following the below procedure.

・

Stand the lens vertically. Hold the focus ring so as to position [B601] inwards, then tighten two screws (#644).

Then in the same way for the rest, tighten the four screws (#644) for the two of [B601].

・

Tighten the two screws (#664 #644) for [B604].

・

Check the operations of the focus ring again.
