Shutter
This setting automatically adjusts shutter value to maintain a constant exposure while keeping
iris aperture consistent. If you want to maintain a fixed depth of field, this is the setting to
choose. It's worth mentioning that the subtle automatic adjustments of the shutter may have an
effect on motion blur. It's also worth keeping an eye out for any flicker that may be introduced
from various light fixtures on indoor shoots. The auto iris feature is not available when the
'shutter' auto exposure mode is selected.
Shutter + Iris
