Previewing Depth of Field
When LPREVIEW DEPTH OF FIELD is assigned to a function button (P39), pressing the button stops aperture down to the selected setting, allowing depth of field to be previewed in the display.
Sensitivity and Motion Blur
If you choose a narrow aperture when the subject is poorly lit, the shutter speed selected by the autoexposure program may not be fast enough to prevent motion blur (see the top illustration at right). For faster shutter speeds that reduce motion blur as shown in the second of the two illustrations at right, select a higher sensitivity.
