Focus Search Priority
When the camera is set to NORMAL or MACRO focus, it begins
searching for focus from the last focus position. However, you
can use the buttons to change this behavior. This
feature is useful when there are multiple objects at different
distances in the focus region.
z
Holding the button while pressing the Shutter halfway
down causes the camera to begin searching for focus from
the farthest position (infinity in
NORMAL mode and 0.8 m in
MACRO mode), thus making the camera more likely to focus
on an object in the background.
z
Holding the button while pressing the Shutter halfway
down causes the camera to begin searching for focus from
the nearest position (0.8 m in
NORMAL mode and 0.1 m in
MACRO mode), thus making the camera more likely to focus
on an object in the foreground.
Hints on Using Manual Focus
z
Make sure to adjust the diopter control properly before
using manual focus with the microdisplay (see page 19).
z
To find the best focus position, adjust the focus so that the
image looks like it is in focus on the active display. From this
position, press the
button until the image begins to blur,
then press the button until the image begins to blur.
Then set the focus position halfway between the locations
where the image began to blur.
z
To lock focus for a set of pictures, let the camera find the
best focus using the
NORMAL setting, then switch to MANUAL
FOCUS . The focus will then be locked at that distance until
you adjust it manually or switch to another focus setting.
