Average “G” value of the three images shoot with checking lens: (b)

1)

Calculate aperture error using the following formula, and check that the aperture error is within the specification.

Aperture error = Average “G” value of master lens (a) - Average “G” value of checking lens (b)

Aperture error = –15 to +10 (Wide end: 24mm)

2)

When the aperture error is out of specification, perform “4-2-2. Aperture Diameter Adjustment”.
