distorted

If a subject has suddenly crossed in front of the camera, it may
appear slightly distorted because this camera uses a MOS
image sensor.
This is normal and not indicative of any problem.

The subjects sometimes appear distorted owing to the
characteristics of the wide-angle lens used. This is normal and
not indicative of any problem.

When the flash is fired
during shooting, only
the top or bottom of
the screen becomes
lighter

p
With a MOS image sensor, the shooting timing differs slightly
between the top left and bottom right of the screen. This means
that when the flash is fired, the bottom of the screen will
become lighter in the field concerned and the top will become
lighter in the next field.
This is normal and not indicative of any problem.

This phenomenon occurs because the pixels are arranged
systematically on each image sensor. It is noticeable when the
spatial frequency of a subject and the pixel pitch are brought
into proximity so change the camera angle or take other such
action.
