Basic Photography
During Recording
While pictures are being recorded to the memory card, the green (AF) lamp will blink
and a
( recording) or ( wait) icon will be displayed in the monitor. The camera can
continue to take pictures until the icon is displayed. Do not turn the camera off,
eject the memory card, or remove or disconnect the power source while the
green (AF) lamp is blinking or the
or icon is displayed. Cutting power or
removing the memory card in these circumstances could result in loss of data or in
damage to the camera or card.
If Both the Green and Red Lamps Blink
If the green (AF) and red ( ) lamps blink together, an error has occurred. Check the
message displayed in the monitor (
106).
Low Battery
If the fl ash fi res when the low battery icon is displayed, the monitor will turn off while
the Speedlight recharges.
Getting Good Results with Autofocus
Autofocus performs best when there is contrast between the subject and the back-
ground and the subject is evenly lit. It does not perform well if the subject is very dark
or moving rapidly, if there are objects of sharply differing brightness in the scene (e.g.,
the sun is behind your subject and their features are in deep shadow), or if there are
several objects at different distances from the camera at the center of the frame (e.g.,
your subject is inside a cage).
The AF-Assist Illuminator
If lighting is poor, the built-in AF assist illuminator will light
when the shutter-release button is pressed halfway, allowing
the camera to focus even when the subject is poorly lit. When
the camera is zoomed all the way out, the AF-assist illuminator
has a range of 0.4 – 2.0 m (1´4˝ – 6´7˝). The range at maximum
zoom is 0.4 –1.5 m (1´4˝ – 4´11˝). The AF-assist illuminator is
not available at scene mode settings of (Landscape),
(Night landscape), (Museum), (Fireworks show), (Sports), and
(Dusk / Dawn)
(
26–29). When AF Area Mode is set to Manual (
79) or (Portrait), (Night
portrait), or
(Close up) is selected in scene mode (
25–28), the AF-assist illumina-
tor will only light when the center focus area is selected.
