1) Optical characteristics
The proper lens is vital for obtaining full
performance from the camera. The exit pupil
distance is particularly important for a 3CCD
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 3CCD are recommended. If another lens is
contemplated, check the performance
beforehand.
4.0mm or less
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 45).
Note: The HV-HD201 uses lens connector wiring
prescribed by the EIAJ (Electronic Industries
Association of Japan). Refer to page 64.
