Target Sighting - Pentax W-821NX Basic Instruction Manual

3.5 Target sighting

[Auto focus]
The Auto focus mechanism is very precise but will not function under every condition. There is a
slight possibility of focusing failure owing to brightness, contrast, the shape and size of the
target. In such a case, press the AF button and focus on the target by operating the Power focus
key or the Focus ring.
