Fitting the zoom lens
It is important to fit the lens correctly, as
otherwise damage may result. Be sure to refer to
the section "Mounting the Lens" (page 39).
Viewfinder
• Do not leave the unit with the eyepiece pointing
directly at the sun.
The eyepiece lens can concentrate the sun's
rays and melt the interior of the viewfinder.
• Do not use the viewfinder close to strong
magnetic fields. This can cause picture
distortion.
About the LCD panels
The LCD panel fitted to this unit is manufactured
with high precision technology, giving a
functioning pixel ratio of at least 99.99%. Thus a
very small proportion of pixels may be "stuck",
either always off (black), always on (red, green,
or blue), or flashing. In addition, over a long
period of use, because of the physical
characteristics of the liquid crystal display, such
"stuck" pixels may appear spontaneously. These
problems are not a malfunction. Note that any
such problems have no effect on recorded data.
Phenomena specific to image sensors
Note
The following phenomena that may occur in images are
specific to image sensors. They do not indicate a
malfunction.
White flecks
Although the image sensors are produced with
high-precision technologies, fine white flecks
may be generated on the screen in rare cases,
caused by cosmic rays, etc.
This is related to the principle of image sensors
and is not a malfunction.
The white flecks especially tend to be seen in the
following cases:
- when operating at a high environmental
temperature
- when you have raised the gain (sensitivity)
- when using the slow shutter
Vertical smear
When an extremely bright object, such as a strong
spotlight or flashlight, is being shot, vertical tails

be distorted.
Aliasing
When fine patterns, stripes, or lines are shot, they
may appear jagged or flicker.
