Shooting Features
A, B, C, D Modes (Setting the Exposure for Shooting)
Pictures can be shot with greater control by setting the
quick menu (A73) or shooting menu (A54) items in
addition to setting the shutter speed or aperture value
manually according to shooting conditions and
requirements.
The focus area for autofocus differs depending on
the setting of AF area mode that can be selected in the A, B, C or D tab after
pressing the d button.
When AF area mode is set to Auto (default setting), the camera has nine focus
areas, and automatically selects the focus areas containing the subject closest to
the camera. When the subject is in focus, the focus area (active focus area) lights
in green (maximum of nine areas).
The procedure for shooting pictures at the desired brightness (exposure) by
adjusting the shutter speed or aperture value is called “determine exposure”.
The sense of dynamism and amount of background defocus in pictures to be shot
vary depending on the combinations of shutter speed and aperture value even if
the exposure is the same.
Rotate the command dial to set the shutter speed and aperture value.
