recorded. The focus may become blurry when
recording subjects at the beach, at night views or
in scenes involving fireworks or special lights.
Recording a subject in dark surroundings
The unit cannot focus correctly because the light
information that comes through the lens
decreases considerably.
Recording a fast-moving subject
As the focus lens-inside moves mechanically, it
cannot keep up with a fast-moving subject.
When, for example, recording a sports event with
fast moving subjects, the focus may lose its
sharpness.
Recording a subject with little contrast
It is easy to bring subjects with a sharp contrast
or vertical lines or stripes into focus. This means
that a subject with little contrast, such as a white
wall, may become blurry because the unit
achieves focus based upon the vertical lines of
an image.
