• The setting is stored along with the exposure setting.

• In certain situations the AF system is unable to set the distance 

correctly, e.g. when:

 

– the distance to the subject you are aiming at is outside the 

available range, and/or

 

– the subject is not sufficiently illuminated (see next section).

Such situations and subjects are indicated by:

 

– The color of the rectangle changing to red

 

– The 11-field metering display changes to a single red rectangle

The shutter button (8) is not locked regardless of whether or not the 

distance setting is correct for the relevant subject.

AF AUXILIARY LIGHT
The built-in AF auxiliary light (2) extends the operating range of the AF 

system to take account of poor lighting conditions. If the function is 

active, this light is lit under appropriate conditions as soon as the 

shutter button (8) is pressed.

Select 

AF Assist Lamp

 in the menu, and the desired setting in the 

submenu

The AF auxiliary light illuminates a range of approximately 4m. 

Therefore, in poor lighting conditions AF mode is not available at 

distances beyond this limit.
