D Shutter Speed and Aperture
The same exposure can be achieved with different
combinations of shutter speed and aperture, allowing
you to freeze or blur motion and control depth of field.
The following figure shows how shutter speed and
aperture affects exposure. When the ISO sensitivity
setting (A138) is changed, the range of shutter speeds
and aperture values at which the correct exposure can
be obtained also changes.
Fast shutter speed: 1/1,000 s Slow shutter speed: 1/30 s
Large aperture
(small f-number): f/2.7
Small aperture
(large f-number): f/7.2
