D Cautions: Auto ISO Sensitivity Control
• If the value currently selected for [ ISO sensitivity ] is higher than that
chosen for [ Maximum sensitivity ], the value chosen for [ ISO sensitivity ]
will serve as the upper limit for auto ISO sensitivity control.
• During flash photography, shutter speed is limited to the range defined by
the values selected for Custom Settings e1 [
Flash sync speed ] and e2
[ Flash shutter speed ]. If the value selected for [ Minimum shutter speed ]
is not in this range, the value selected for Custom Setting e2 [ Flash shutter
speed ] becomes the effective minimum shutter speed.
• Except in mode M , videos are recorded using auto ISO sensitivity control.
Auto ISO sensitivity control can be enabled for video recording in mode M
by selecting [ ON ] for [ ISO sensitivity settings ] > [ Auto ISO control (mode
M) ] in the video recording menu.
