Problem Subjects for Autofocusing
The EOS D30 has a precision AF system that can focus on most subjects. However, it may not
be able to focus on subjects (in-focus indicator (•) blinks) in particular conditions such as the
following:
Difficult-to-Focus Subjects
Very low-contrast subjects, such as a blue sky or single-color wall
Subjects in very dark locations
Extremely backlit or reflective subjects, such as a shiny new car
Overlapping nearby and distant objects, such as cage bars and the animal inside the cage
In such cases, use one of the following procedures:
(1) Focus on an object that is at the same distance as the desired subject, apply Focus Lock,
then recompose the picture.
(2) Set the lens focus mode switch to MF (or M on older lenses), and focus manually.
MF Manual Focus
Set the lens focus mode switch to
(MF) (or (M) on older lenses).

Focus on the subject.
Turn the manual focusing ring on the lens
until the subject appears sharp in the
viewfinder.
If you press and hold the shutter button down halfway as you focus manually, you
will see the focusing point where the subject is focused, and the in-focus indicator
(•) will light.
