Difficult to focus subjects

Using Autofocus (AF) (continued)

The autofocus feature of this camera is effective for most subjects. However, subjects like the ones described below could be difficult to focus with the autofocus feature. If focusing with the CCD is not successful, after you half-press the shutter button, the AF correct mark in the lower left corner of the viewfinder blinks. You can still take a picture under this condition by full-pressing the shutter button.

Subject of low contrast

A subject without distinct patterns could be difficult to focus.

Subject with center glare

A subject with center glare could be difficult to focus.

Two objects at different distances from the camera

The camera cannot autofocus on a single subject with two objects at different distances from the camera in the viewfinder.

Subject in light from street lights and windows

A subject at night in light from street lights or from building windows could be difficult to focus.

For these situations, position the AF target mark in the viewfinder on an object that is at the same distance from the camera as the subject, and then half-press the shutter button to lock the focus. While keeping your finger half-pressed on the shutter button, frame the picture that you want to shoot, and then full- press the shutter button. (➞ 65)

You can also set the focus mode switch to the MF mark to select manual focusing, and then adjust the focus manually with the manual focus ring. (➞ 68)
