Lens
CAUTION:
Observe the dimensions of the lens mounting
selection as illustrated at the right.
If the dimensions are not observed, do not use
such a lens, because the lens and the camera
will be damaged.
Lens selection
1) Optical
characteristics
The proper lens is vital for obtaining full
performance from the camera. The exit pupil
distance is particularly important for a 3 CCD
type camera. If too short, vertical color
shading can appear in the picture.
Also, as the lens iris approaches fully open,
problems such as loss of +
resolution, shading and flare (overall image
"white-out") can detract from picture quality.
When using in applications that call for open iris,
the lenses for 3 CCD are recommended. If
another lens is contemplated, check the
performance beforehand.
2) Auto iris lens
Main types are Video (with self contained iris
amplifier) and DC (DC voltage applied to open lens
iris) and manual over-ride (e.g., Cosmicar). Lenses
without self-contained iris amplifier are not
compatible.
Camera settings differ according to the auto iris lens
type (see page 24).
Note:
The HV-D20 uses lens connector wiring
prescribed by the EIAJ (Electronic Industries
Association of Japan). Refer to page 65
