Usage Precautions
Notes on Cable Configurations
The presence of lighting equipment and television receivers nearby may result in video noise. In such
cases, change the cable configurations or placement.
Notes on Attaching The Lens
How to Clean a Sensor
Avoiding Dust Particles
When attaching the lens to the camera, stray dust and other particles may adhere to the sensor
surface and rear surface of the lens. Be careful of the following when attaching the lens.
l
Work in a clean environment.
l
Do not remove the caps from the camera and lens until immediately before you attach the lens.
l
To prevent dust from adhering to surfaces, point the camera and lens downward and do not
allow the lens surface to come into contact with your hands or other objects.
l
Always use a blower brush to remove any dust that adheres.
l
Never use your hands or cloth, blow with your mouth, or use other methods to remove dust.
Phenomena Specific to CMOS Image Sensors
The following phenomena are known to occur on cameras equipped with CMOS image sensors.
These do not indicate malfunctions.
l
Aliasing
: When shooting straight lines, stripes, and similar patterns, vertical aliasing (zigzag
distortion) may appear on the monitor.
l
Blooming
: When strong light enters the camera, some pixels on the CMOS image sensor may
receive much more light than they are designed to hold, causing the accumulated signal charge
to overflow into surrounding pixels. This “blooming” phenomenon can be seen in the image but
does not affect the operation of the camera.
l
Fixed pattern noise
: When shooting dark objects in high-temperature conditions, fixed pattern
noise may occur throughout the entire video monitor screen.
l
Defective pixels
: Defective pixels (white and black pixels) of the CMOS image sensor are
minimized at the factory according to shipping standards. However, as this phenomenon can be
