Hint
The difference in shutter speed at which ISO sensitivity starts to change
between [Faster], [Fast], [Standard], [Slow], and [Slower] is 1 EV.
Note
If the exposure is insufficient even when the ISO sensitivity is set to [ISO AUTO
Maximum] in [ISO AUTO], in order to shoot with an appropriate exposure, the
shutter speed will be slower than the speed set in [ISO AUTO Min. SS].
In the following situations, the shutter speed may not function as set:
When the maximum shutter speed has changed based on the [ Shutter Type]
setting.
When using the flash to shoot bright scenes with the [
Shutter Type] set to
[Electronic Shut.]. (The maximum shutter speed is limited to the flash-synching speed
of 1/100 seconds.)
When using the flash to shoot dark scenes with the [Flash Mode] set to [Fill-flash].
(The minimum shutter speed is limited to the speed automatically determined by the
