Shutter Button Operation and Autofocus

The Shutter button has a two step construction. Press halfway (to the first step) to activate focusing and metering, and press completely (to the second step) to release the shutter and make the exposure.

1Press the Shutter button halfway to activate autofocus. When the subject is focused, the corresponding focusing point momentarily lights red. (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 Selection mode when the AF mode is set to AI Servo.

The In-focus indicator does not light up in AI Servo AF mode.

2At the same time, the camera determines the shutter speed and aperture value combination (exposure value), and the results are displayed in the Top 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.
