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
Aliasing
When fine patterns, stripes, or lines are shot, they
may appear jagged or flicker.
100 Important Notes on Operation
Focal plane (PMW-F5 only)
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 (PMW-F5 only)
The luminance at the top and bottom of the screen
may change when shooting a flashlight beam or a
light source that quickly flashes.
Flicker (PMW-F5 only)
Shooting under the lights of a discharge lamp
such as a fluorescent lamp, sodium-vapor lamp,
mercury-vapor lamp, etc., may cause flickering,
color change, or vertical stripes.
Note on the display
• Pictures on the viewfinder screen may be
distorted by the following operations:
—Changing the video format
—Starting playback from the Thumbnail
screen
• When you change the eye direction in the
viewfinder, 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.
Fragmentation
If pictures cannot be recorded/reproduced
properly, try formatting the recording medium.
While repeating picture recording/playback with
a certain recording medium for an extended
period, files in the medium may be fragmented,
disabling proper recording/storage. In such a
case, make a backup of clips in the medium then
perform formatting of the medium using "Format
Media" (page 85) in the Media menu.
