ADVANCED OPERATIONS

• When using the Three-Level Auto (red, green, and

yellow settings) mode, the aperture value is

adjusted as shown in the table. When the flash is

fully charged, the shutter speed also varies within

the shutter speed range of 1/60 to a slower speed

which does not cause camera shake. The slowest

shutter speed varies according to the lens focal

length. When a 645A - lens is use, the shutter

speed will be set to 1/60 of second.
