■ Depth of Field

The depth-of-field indicators on the lens show the 

approximate depth of field (see page 138 for more 

information). If the camera offers depth-of-field preview (stop 

down), depth of field can also be previewed in the viewfinder.

If desired, autofocus can be over-ridden by rotating the 

lens focus ring while the shutter-release button is pressed 

halfway (or, if the camera is equipped with an AF-ON 

button, while the AF-ON button is pressed). To refocus 

using autofocus, press the shutter-release button halfway 

or press the AF-ON button again.
