CONTROLLING THE APERTURE

If depth of field is important to your pictures, use Aperture Priority

APERTURE PRIORITY

FOR DIRECT CONTROL OF THE APERTURE, SHOOT IN APERTURE PRIORITY MODE. THE CAMERA WILL AUTOMATICALLY ADJUST THE SHUTTER SPEED TO MATCH THE LIGHTING CONDITIONS. YOU CAN SET BOTH ASPECTS IF YOU SHOOT IN MANUAL MODE.

F-NUMBERS

ROTATE THE CAMERA’S MAIN DIAL OR USE ITS TOUCHSCREEN (WHERE AVAILABLE) TO CHANGE THE SIZE OF THE APERTURE. YOU’LL BE ABLE TO FREELY SELECT F-NUMBERS FROM THE RANGE OFFERED BY THE LENS – THE DISPLAY WILL CHANGE AS YOU DO SO.

DOF PREVIEW

IF YOU USE A DSLR, YOU WON’T BE ABLE TO SEE THE EFFECT OF THE CHANGING APERTURE THROUGH THE OPTICAL VIEWFINDER. TO DO THIS, YOU’LL NEED TO ACTIVATE DEPTH OF FIELD (DOF) PREVIEW, USUALLY A BUTTON NEAR THE LENS MOUNT.

LIVE VIEW

THE IMAGE WILL BE SHOWN AT THE SELECTED APERTURE, BUT IT CAN BE DARK – UNLIKE THE IMAGE IN THE ELECTRONIC VIEWFINDER OF A MIRRORLESS CAMERA, WHICH STAYS BRIGHT. SO TRY USING DOF IN COMBINATION WITH LIVE VIEW.
