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 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.
applications that call for open iris, the lenses
for 3CCD are recommended. If another lens is
contemplated,
check
beforehand.
3) Flangeback adjustment of zoom lens
1) Set the lens to telephoto and pickup an
image more than 3 meters distant.
the focus ring to adjust the focus.
2) Set the lens to wide angle and while using
care not to disturb the focus ring, turn the

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 44).
