u Caution
• When shooting using the automatic exposure control, note
the following points.
• Images can be taken with the set aperture value but an
exposure deviation may occur.
• When shooting with the optical viewfinder, you cannot
check the shutter speed and ISO sensitivity before
shooting because the metering is performed immediately
before the shutter is released. When shooting with Live
View, you can check the shutter speed and ISO sensitivity
before shooting because the aperture is always narrowed
down.
• When a lens with automatic diaphragm is attached, the
aperture is narrowed down immediately before the shutter
is released, causing a time lag in the shutter release.
