Subjects With Which Auto Focusing May Not Work
The auto focus function requires subject contrast. Auto focusing may not be possible
with the types of subjects described below. If this is the case, either switch to the
manual focus mode and focus manually or point the camera at an object the same
distance as the object you want to photograph, lock the focus using the focus lock
mechanism, then take the picture. (See next page)
➊ When differences between light
and shade are not clear (blue
skies, white walls and other ob-
jects with no contrast)
➌ Subjects with continuous re-
peated patterns (building exte-
riors, blinds, etc.)
➍ Brightly shining subjects like
the sun or light sources or
objects in which these are re-
flected (car bodies, water sur-
faces, etc.)
➎ When the object on which you want to focus is far smaller than the
focus frame
