MEMO
• The measured exposure level remains locked as long as the AE lock
button is kept pressed or the shutter release button is kept pressed
halfway (even after 20 seconds).
• With the custom function number [CF4], you can select the function of
the AE lock button between auto focusing and auto exposure metering.
See page 137.
• When the AE lock button is pressed, audible PCV signal is heard. This
audible PCV signal can be turned off. See page 87.
• The auto pop-up built-in flash function does not work while the AE lock
is in use.( goes off of the LCD panel).
•
AE lock does not work in the metered manual mode and bulb exposure mode.
• If a zoom lens whose maximum apperture varies depending on the
focal length, the combination of shutter speed and aperture value
changes depending on the zooming position even while the AE lock is
working. However, the exposure value does not vary, therefore, a
picture is taken at the brightness level set by the AE lock.
You can lock the exposure setting before you take the picture.
If the subject is too small or backlit and a proper exposure setting
cannot be obtained, you can zoom in on the subject to obtain the
proper exposure setting. Then lock the exposure setting and
recompose to take a picture.
