During Recording
• While pictures are being recorded, the number of exposures (A 20) remaining will blink. Do not
open the battery-chamber/memory card slot cover while pictures are being recorded. Cutting
power or removing the memory card in these circumstances could result in loss of data or in
damage to the camera or card.
• It may take some time for the picture to be saved depending on the current settings or the
shooting conditions ( F 11).

Subjects Not Suitable for Autofocus
Autofocus may not perform as expected in the following situations. In some rare cases, the subject
may not be in focus despite the fact that the focus area or the focus indicator glows green.
• Subject is very dark
• Objects of sharply differing brightness are included in the scene (e.g. the sun behind the subject
makes that subject appear very dark)
• No contrast between the subject and surroundings (e.g. a portrait subject, wearing a white shirt, is
standing in front of a white wall)
• Several objects are at different distances from the camera (e.g. the subject is inside a cage)
• Regular geometric patterns (e.g. window blind or windows in a skyscraper)
• Subject is moving rapidly
In the situations noted above, try pressing the shutter-release button halfway to refocus several
times, or try focusing on another subject that is at the same distance from the camera as the
intended subject (
A 39).
C
Touch Shutter
At the default setting, the shutter can be released by simply tapping a subject in the monitor
(
A 38) without pressing the shutter-release button. The Touch shutter option can be changed to
the Touch AF/AE option, which allows the camera to set the focus and exposure on the subject
that is tapped on the monitor. When using the Touch AF/AE option, the picture is taken by pressing
the shutter-release button.
C
AF-assist Illuminator and Flash
If the subject is poorly lit, the AF-assist illuminator ( A 89) may light when the shutter-release button
is pressed halfway, or the flash ( A 54) may fire when the shutter-release button is pressed all the
way down.
C
To Make Sure You Do Not Miss a Shot
If you are concerned that you might miss a shot, press the shutter-release button all the way without
first pressing it halfway.
C
Motion Detection
In G (easy auto) mode or A (auto) mode, when the camera detects subject movement or camera
shake, ISO sensitivity and shutter speed are increased to reduce blurring. In this case, the shutter
speed indicator will turn green.
