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.
