A histogram is a graph showing the 
brightness of an image on the horizontal 
axis and the number of pixels on the 
vertical axis (distribution chart of the 
brightness). The histogram will help you 
detect the brightness of the image you 
have taken. For instance, the graph 
peak tends to appear on the left side for 
a darker image, and the graph peak 
tends to appear on the right side for a 
brighter image. 
In general, when the exposure metering of your image is well-balanced, 
the graph peaks tend to appear in the middle. 
On the contrary, when the exposure metering of the subject is imbalanced, 
that is with dark areas and/or bright areas, the peaks will appear on the 
sides rather than in the middle.

• If you press and hold the OK/Display button for more than 1 second, 

the LCD Bright Mode is activated. The LCD monitor turns brighter 
for a certain amount of time. (1p.35)

• Under shooting conditions where camera shake is likely to occur, 

 (Anti-shake warning) will be displayed. Take pictures with 

the camera secured on a tripod or other stable surface.

• All the camera buttons function as usual even when the LCD backlight 

is off. Press the shutter release button to take pictures as usual.
