FOCUS LOCK FUNCTION

ADVANCED OPERATIONS

132

In the Spot Metering Mode, the camera focuses with the

spot metering / focusing area of the viewfinder. If you

shoot without positioning the spot metering / focusing area

on the main subject, the main subject will not be focused

properly.

Set the AF frame selector to [ ].

1. When the composition does not allow the autofo-

cus frame to be placed over the most important

subject, the camera will focus on the background

as shown in the illustration.

• The focus lock can be used in the 3-point AF Mode and

Spot AF Mode.

• The focus lock does not operate when the AF mode

selector is at [ C ].

2. To prevent this, focus on the main subject with the

spot metering / focusing area. Depress and hold the

shutter release button halfway down. The in-focus

indicator remains on, indicating that the focus is

temporarily locked.

3. While holding the shutter release button halfway

down, re-aim the camera or recompose the picture,

then depress the shutter release button fully to

release the shutter.

• Lifting your finger off the shutter release button clears

the in-focus indicator [ ] in the viewfinder and cancels

the focus lock function.

• To refocus on another subject, lift your finger off the shut-

ter release button.
