Manual exposure control is recommended in the 
following situations:

● When shooting using reverse lighting or when the 

background is too bright.

● When shooting on a reflective natural background such as 

at the beach or when skiing.

● When the background is overly dark or the subject is bright.

Set the Power Switch to “M”.

Set “p” to “MANUAL”. (

Like the pupil of the human eye, the iris contracts in well-
lit environments to keep too much light from entering, 
and dilates in dim environments to allow in more light.
Use this function in the following situations:

● When shooting a moving subject.

● When the distance to the subject changes (so its size in the 

LCD monitor or the viewfinder changes), such as when the 
subject is backing away.

● When shooting on a reflective natural background such as 

at the beach or when skiing.

● When shooting objects under a spotlight.

● When zooming.

Set the Power Switch to “M”.

Set “p” to “MANUAL”. (

● The exposure control indicator appears.

Adjust zoom so that the subject fills the LCD monitor

Backlight compensation brightens the subject quickly.
With simple operation, backlight compensation feature 
brightens the dark subject portion by increasing the 
exposure.

Set the Power Switch to “M”.

Press BACK LIGHT so that the Backlight 

Compensation indicator “

To cancel Backlight Compensation
Press BACK LIGHT twice so that the “

Using Backlight Compensation may cause the light around 
the subject to become too bright and the subject to become 
white. 

Selection of a spot metering area enables more precise 
exposure compensation. You can select one of the three
