Note on laser beams
Laser beams may damage the CMOS image
sensors. If you shoot a scene that includes a laser
beam, be careful not to let the laser beam be
directed into the lens of the camcorder.
About the LCD monitor
• Do not leave the LCD monitor facing direct
sunlight, as this may damage the LCD monitor.
• Do not press/swipe the LCD monitor forcefully,
or leave objects on the LCD monitor, as it may
cause a malfunction, such as picture
irregularity, etc.
• The LCD monitor may become warm in use.
This is not a malfunction.
About the stuck pixels
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, and will not be
recorded on recording media.
Phenomena specific to CMOS image
sensors
The following phenomena that may appear in
images are specific to CMOS (Complementary
Metal Oxide Semiconductor) image sensors.
They do not indicate malfunctions.
White flecks
Although the CMOS 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 CMOS 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)
• when operating in Slow-Shutter mode
104 Important Notes on Operation
Aliasing
When fine patterns, stripes, or lines are shot, they
may appear jagged or flicker.
Flicker
If recording is made under lighting produced by
discharge tubes, such as fluorescent, sodium, or
mercury-vapor lamps, the screen may flicker,
colors may vary, or horizontal stripes may appear
distorted.
In such cases, set the Flicker-Reduction function
to Auto mode (page 41).
In some cases, such phenomena may not be
improved with the Flicker-Reduction function.
It is recommend to set the electronic shutter speed
to 1/100 sec. in 50-Hz areas and to 1/60 in 60-Hz
areas.
Focal plane
Owing to the characteristics of the pickup
elements (CMOS sensors) for reading video
signals, subjects that quickly move across the
screen may appear slightly skewed.
Flash band
The luminance at the top and bottom of the screen
may change when shooting a flashlight beam or a
light source that quickly flashes.
Note on the EVF display
• Pictures on the LCD monitor and EVF screen
may be distorted by the following operations:
—Changing the video format
—Rec Review
—Starting playback from the Thumbnail
screen
—Reversing the LCD monitor
—Switching the Expanded Focus display
• When you change the eye direction in the EVF,
you may see primary colors red, green, and
blue, but this is not a defect of the camcorder.
These primary colors are not recorded on any
recording media.
