Focusing
In the following situations, ignore the in-focus indicator (•).
When the subject is obscured by an object such as a fence in the foreground, use
Single Area AF mode and select the subject ’ s focus ar ea ( descri bed on page 9-1 ) or
focus manually with the clear matte field.
With an extremely bright object near your subject, use Single Area AF mode and
select the subject’s focus area, or focus manually with the clear matte field.
When using a linear polarizing filter or other special filter such as a soft-focus
filter, focus manually with the clear matte field.
A circular polarizing filter can be used in connection with autofocus operation.
Antialiasing Filter or IR Filter: Effect on Focus
The antialiasing or IR filters cause the distance indicator on your lens to show that an
object is closer than it actually is. This is particularly true when you use a wide angle lens.
The antialiasing filter also slightly increases the minimum distance at which you can
focus. It does not affect focusing, either manual or automatic.
