Recording (continued)
Brightness or colouring of recorded picture different from real life.
●
When recording under fluorescent or LED lighting fixture etc., increasing the shutter speed may
introduce slight changes to brightness and colour. These are a result of the characteristics of the
light source and do not indicate a malfunction.
●
When recording subjects in extremely bright locations or recording under fluorescent lighting, LED
lighting fixture, mercury lamp, sodium lighting etc., the colours and screen brightness may change
or horizontal striping may appear on the screen.
Reddish horizontal streaks appear on the screen during recording.
●
This is characteristic of the MOS sensors, which serve as the camera's pickup sensors. The streaks
appear when the subject has a bright part. Some unevenness may occur in the surrounding areas,
but this is not a malfunction. It is recorded in motion pictures but is not recorded on still pictures.
●
It is recommended that you take pictures while taking care not to expose the screen to sunlight or
any other source of strong light.
Motion picture recording stops midway.
●
If the surrounding temperature is high, or a motion picture is recorded continuously, [
displayed and recording may be stopped halfway through to protect the camera.
●
With some cards, access display may appear briefly after recording, and recording may end midway.
●
Use a card of SD Speed "Class 4" or higher. If recording stops even when using a card of the
recommended speed class, the data writing speed has dropped. If this happens, we recommend
backing up the data on the memory card and formatting it (→74).
Panorama picture recording stops before finishing.
●
If the pan motion of the camera is too slow, the camera assumes that the operation has been
aborted and stops recording.
●
If the pan motion of the camera is too shaky when it is moved toward the recording direction, the
camera stops recording.
→ To record panorama pictures, pan the camera in a small circular motion parallel to the recording
direction at a speed of approx. 8 seconds per revolution (guideline).
The subject cannot be locked. (AF track fails)
●
If the colour of the subject is similar to that of its background, AF Tracking may not function. Set the
AF lock to the colours specific to the subject.
