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 affect exposure.
Shutter speed
Fast shutter speed
Slow shutter speed
If the ISO sensitivity setting is changed (A 53, 111), the range of shutter speed and
aperture settings that will achieve optimal exposure also changes.

Lens Aperture Ring
When using a CPU lens equipped with an aperture ring, lock the aperture ring at the minimum
aperture (highest f-number). Type G lenses are not equipped with an aperture ring. When a CPU
lens is mounted, adjust the aperture from the camera.
