While pictures are being recorded, the number of exposures remaining will blink. Do not open the 
battery-chamber/memory card slot cover while pictures are being recorded. Cutting power or 
removing the memory card in these circumstances could result in loss of data or in damage to the 
camera or card.

Autofocus may not perform as expected in the following situations. In some rare cases, the subject 
may not be in focus despite the fact that the active focus area and the focus indicator glow green:

• Subject is very dark
• Objects of sharply differing brightness are included in the scene (e.g. the sun is behind the subject 

and is in deep shadow)

• No contrast between the subject and surroundings (e.g. when the subject is standing in front of a 

white wall, wearing a white shirt)

• Several objects are at different distances from the camera (e.g. the subject is inside a cage)
• Subject is moving rapidly
In the situations noted above, try pressing the shutter-release button halfway to refocus several 
times, or focus on another subject and use focus lock (

A 102). When using focus lock, be sure that 

the distance between the camera and the subject with which focus was locked is the same as that 
for the actual subject.

See “AF Area Mode” (

A 101) or “Face Priority” (A 103) for more information about Face Priority.

D

If the subject is poorly lit, the AF-assist illuminator (

A 123) may light when the shutter-release 

button is pressed halfway, or the flash (

A 28) may fire when the shutter-release button is pressed 

all the way down.
