When Auto Focus is Failed

The auto focus function requires contrast on subject. Auto focusing may fail to achieve focus with certain subjects described below. In such cases, either switch to the manual focus mode and focus manually or focus an object at the same distance as the object you want to photograph, lock the focus using the focus lock mechanism, then take a picture.

•Low-contrast subject (blue skies, white walls and other objects)

•Two or more objects overlapping at different distances within the focus frame (animals in cages, etc.)

•Subjects with continuous repeated patterns (building exteriors, blinds, etc.)

•Extremely backlit reflective subjects (car bodies, water surfaces, etc.)

•Or when the subject is far smaller than the focus frame
