7. ABOUT THE LENSES
7.1. Lens (optional) Selection and Camera Setting
• When using the flickering-reduction function outdoors or under the fluorescent lighting, use the auto-iris lens.
Follow the procedure below to perform the setting:
1. Set the Lens Auto/Manual selector switch of the mode switch (6) to "AUTO" position (factory-preset
position).
2. Set the lens selector switch (5) to "DC" or "VIDEO" position depending on the type of auto-iris lens to use.
Factory-preset for "DC" position.
3. To reduce flickering, set the flickering-reduction switch of the mode switch to "1/100" position
(NTSC.version), "1/120" position (PAL version).
• When using the flickering-reduction function indoors or in locations where the lighting condition does not
much change, you can use the manual or fixed iris lens by making the following camera settings:
1. Set the Lens Auto/Manual selector switch of the mode switch (6) to "MANU" position. Factory-preset for
"AUTO" position.
2. Set the flickering-reduction switch of the mode switch to "(1/60)" (NTSC version) position,"(1/50)" (PAL
version) position.
Notes
• When the flickering-reduction switch is set to "1/100" ("1/120") position, the
automatic sensitivity adjustment function cannot be used even if the Lens
Auto/Manual selector switch of the mode switch is set to "MANU" position. Use
the auto-iris lens.
• To avoid damaging the internal sections of the camera's lens mount, be sure
that the lens flange is less than 5 mm thick as illustrated on the right.
• C-mount lenses must be used in conjunction with the Lens Mounting Adapter
CF-5 (optional).
