Autofocus
Autofocus
Although the camera boasts a high-precision auto-
focus system, it may be unable to focus on the sub-
jects listed below.
• Very shiny subjects such as
mirrors or car bodies.
• Fast-moving subjects.
• Subjects photographed through a window or oth-
er refl ective object.
• Dark subjects and subjects that absorb rather than
refl ect light, such as hair or fur.
• Insubstantial subjects, such as smoke or fl ame.
• Subjects that show little contrast with the back-
ground (for example, subjects in clothing that is
the same color as the background).
• Subjects positioned in front of or behind a high-
contrast object that is also in the focus frame (for
example, a subject photographed against a back-
drop of highly contrasting elements).
