APERTURE DIAMETER CHECK/ADJUSTMENT
4-2-1. Aperture Diameter Check
1.
Perform “LENS GENERAL ADJUSTMENT GUIDE 2. APERTURE DIAMETER CHECK” .
Specification: Aperture error = -20 to +5 (WIDE end: 16mm)
2.
If the aperture error does not meet the specification, perform “4-2-2. Aperture Diameter Adjustment”.
4-2-2. Aperture Diameter Adjustment
Equipment
• Adhesive bond (B-10)
1. Adjustment Procedure
1)
Remove the rear light shield barrel and mount block assy.
Fig. 4-2-1
2)
Loosen lightly two screws fixing the aperture connect fork of mount block assy.

Fine-adjust by moving right or left the aperture connect fork, tighten two screws and apply the adhesive bond (B-10) to the indicated
portions.
Fig. 4-2-2
4)
Assemble again and perform “4-2-1. Aperture Diameter Check”. And repeat steps 1) to 3) until the aperture diameter satisfies the
specification. If the aperture diameter does not satisfy the specification, replace the optics block assembly.
