Olympus e-10 Introduction Manual

Normally the camera automatically meters the focus and the exposure when you half-
press the shutter button and locks the AF (automatic focus) and AE (automatic exposure)
at the same time. However, you can lock the exposure by pressing the 

 button

before pressing the shutter button.
If you press the shutter button with the 

 button depressed, only AF is performed

and the exposure does not change.
Conversely, if you press the 

 button with the shutter button half-pressed, the focus

is fixed and you can adjust the exposure.
The exposure is held only as long as the 

 button is depressed and released as

soon as the button is released.

Keep the button pressed down. While the
button depressed, the exposure setting will
not change. When the exposure is locked,
the AEL mark appears in the viewfinder.
If you half-press the shutter button while
holding down the 

 button, automatic

focus also operates.

You can continue to take other pictures at
the same exposure, as long as you keep
the 

 button pressed down.

When you press the 

 button, the exposure setting selected by half-pressing the shutter button

is canceled and the exposure selected with the 

 button press is used. On the other hand, if the

 button is released, then exposure changes as metered automatically with a half-press on the

shutter button.
