Locking Focus

Focus-locking is a technique for bringing a subject into focus which is not

within the autofocus mark (center) of the Camedia C-2500L. It can be

performed as explained below.

While looking into the viewfinder, move the autofocus mark over

the subject you want to photograph and press the shutter

release button down halfway.

This will lock the focus and exposure. The green lamp inside the

viewfinder will light up to indicate the camera is ready to take the pic-

ture.

Without lifting your finger off the shutter release button, com-

pose the photograph as you want and press the shutter release

button down all the way.

AF Illuminator

When the subject is dark, AF illuminator is emitted to cover low bright-

ness.

NOTE

• When holding down the [OK] button and pressing the shutter release

button down halfway after the focus lock, the focus stays locked even

if you remove your finger from the shutter release button.

NOTE

• The illumination range of the fill-in light for focusing is up to 3 m.(9.8

ft.) Even within this range, the subject may not be brought in focus if

available light is below EV2 (approx. 7 luxes).

• Focus-locking is disabled even if the AF illuminator is emitted when

the subject has low contrast.

• AF illuminator is not emitted when a device like a conversion lens is

attached.

• There is no problem if the light from the AF illuminator can be out of

the subject that the Autofocus mark aims at, depending on the dis-

tance to the subject.

• For your safety, never face and fire the AF illuminator at anybody's

face at close range. The illuminator employs a rather directional LED

and can cause slight damage to your eyes.
