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" on page 42.
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
LCD panels are manufactured with extremely
high-precision technology that yields effective
pixel rates of 99.99% or higher. However, very
rarely, one or more pixels may be permanently
dark or permanently lit in white, red, blue, or
green.
This phenomenon is not a malfunction. Such
pixels have no effect on the recorded data, and the
unit may be used with confidence even if they are
present.
Phenomena specific to CCD image
sensors
The following phenomena that may appear in
images are specific to CCD (Charge Coupled
Device) image sensors. They do not indicate
malfunctions.
White flecks
Although the CCD 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 CCD 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 master gain
(sensitivity)
224 Important Notes on Operation
The problem may be alleviated by executing the
APR (automatic pixel noise reduction) function
on the APR page of the MAINTENANCE menu
(see page 156). Pixel noise is reduced to some
extent by automatic black balance adjustment
(see page 55), but the detection capabilities of
that function are limited. For the most effective
correction, execute the APR function.
If "No More White Pixel" appears after the APR
function is executed, then there are no more
detectable white flecks.
In SLS mode, white flecks are more prominent
when you set the shutter speed (number of
frames) to higher values. Executing the
APR(SLS) function on the APR page (see page
156) may alleviate the problem of white flecks in
SLS mode.
Vertical smear
When an extremely bright object, such as a strong
spotlight or flashlight, is being shot, vertical tails
may be produced on the screen, or the image may
be distorted.

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