The shutter button has a two step construction. Press halfway (to the first

step) to activate focusing and metering, and press completely (to the sec

ond step) to release the shutter and make the exposure.

1. Pressing Halfway

1) This activates autofocus. When the

subject is focused, the correspond

ing focusing point momentarily lights
red and the green in-focus indicator

lights up in the viewfinder (in One-

shot AF mode).

• The autofocus system uses five

focusing points.

• The focusing point does not light

up in automatic focus point selec

tion mode when the AF mode is

set to AI Servo.

•The in-focus indicator does not

light up in Al Servo AF mode.

2) At the same time, the camera deter

mines the shutter speed and aper

ture value combination (exposure

value), and the results are displayed

in the LCD panel and viewfinder. If

you remove your finger from the

shutter button, a timer operates to
continuously display the exposure

settings for six seconds.
