DIFFICULT FOCUSING CONDITIONS IN THE AUTOFOCUS MODE
N OTE : For best results with any camera, light source should always come from behind you.
The autofocus mechanism is triggered by contrast--light vs dark. The ill u strations below offer instances
when the autofocus will experience difficulty in determining the primary subject.
Under these four circumstances, we recommend taking advantage of the focus lock function. (see pg 39)
S ubject too dark.
The subject , such as a
blue sky or white walls,
lacks contrast.
Foreground invades
primary subject
.
A fore- or background with
a highly reflective surface
against the sun.
