A: Aperture-Priority Auto

In mode A, you choose the aperture while the camera controls shutter speed for optimal exposure. Small apertures (high f/-numbers) increase depth of field, bringing both the main subject and background into focus. Large apertures (low f/-numbers) soften background details and let more light into the camera, increasing the range of the flash and making photographs less susceptible to blurring. Mode A is only available with CPU lenses.

To take photographs in aperture-priority auto:

1 Rotate the mode dial to A.

2 Rotate the sub-command dial to choose the desired aperture.

3 Frame a photograph, focus, and shoot.
