Description

How Aperture Priority (Av) mode works.

Solution

In this mode, you set the desired aperture and the camera sets the shutter speed automatically to suit the subject brightness

The larger the aperture (smaller f-number) the more blurred the background will become. This effect is suited for portraits. The smaller the aperture (larger f-numbers), the clearer the focus will be for near and far objects.


While pressing the <MODE> button, turn the dial until Av appears on the LCD panel. Then release the <MODE> button

Turn the dial to set the desired aperture

Press the shutter button halfway and focus the subject

  • The shutter speed and aperture will be displayed

Take the picture

  • As long as the shutter speed is not blinking a correct exposure will be obtained
  • If the shutter speed is slower than the reciprocal of the lens focal length (i.e. 1/200 for a 200mm lens) camera shake may cause a blurred picture.
