Subjects Difficult to Focus

Autofocus can fail to achieve focus (viewfinder’s focus confirmation light <o> blinks) with certain subjects such as the following:

Very low-contrast subjects.

(Example: Blue sky, solid-color walls, etc.) Subjects in very low light

Extremely backlit or reflective subjects (Example: Car with a highly reflective body, etc.) Near and far subjects covered by an AF point (Example: Animal in a cage, etc.)

Repetitive patterns

(Example: Skyscraper windows, computer keyboards, etc.)

In such cases, do one of the following:

(1)With One-Shot AF, focus an object at the same distance as the subject and lock the focus before recomposing (p.52).

(2)Set the lens focus mode switch to <MF> and focus manually.

Conditions in which focus is difficult to achieve in the [Live mode] and [u Live mode] AF modes during Live View shooting are listed on page 132.

MF: Manual Focusing

If you hold down the shutter button halfway during manual focusing, the AF point achieving focus will light in red briefly, the beeper will sound, and the focus confirmation light <o> in the viewfinder will light.
