Although the camera boasts a high-precision
autofocus system, it may be unable to focus on the
subjects listed below. If the camera is unable to focus
using autofocus, use focus lock (pg. 23) to focus on
another subject at the same distance and then
recompose the photograph.
• Subjects photographed through a window or other
• Dark subjects and subjects that absorb rather than
reflect light, such as hair or fur.
• Insubstantial subjects, such as smoke or flame.
• Subjects that show little contrast with the
background (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
backdrop of highly contrasting elements).
Very shiny subjects such
as mirrors or car bodies.
The AF-Assist Illuminator
If the subject is poorly lit, the AF-assist illuminator will
light to assist the focus operation when the shutter
button is pressed halfway.
• Avoid shining the AF-assist illuminator directly into
your subject’s eyes. See page 86 for information on
disabling the AF-assist illuminator.
• The camera may be unable to focus using the AF-
assist illuminator in some cases. If the camera is
unable to focus in macro mode (pg. 25), try
increasing the distance to the subject.
• The AF-assist illuminator is not available in K, L,
W, E, H, I, and O modes.
