1/10000, 1/50000 second : Set to setting shutter speed (PRESET shutter). | |
VARIABLE | : Set to shutter speed from 10 second to 1/100000 second (VARIABLE shutter). |
10 to 1/100000 second : Electronic shutter can be set in the range of 10 to 1/100,000 second in 1536 steps.
Shutter speed setting value and exposure time can be derived as follows. (ShutterSpeed:: μsecond)
a)Setting value XYY16 obtained from exposure time.
X = int(log(ShutterSpeed )) − 1
