When using evaluative metering, the
exposure setting is determined when focus
is achieved. The exposure setting and
focus remain locked as long as the shutter
button is pressed down halfway. You can
then recompose the shot while retaining
the exposure setting and focus (→62).
If the camera cannot focus, the in-focus indicator (●) in the viewfinder blinks. If this
happens, you will not be able to take a picture even if you press the shutter button
down fully. Instead, reframe the shot and focus again. See also, “Manual Focus”
(→63).
