the program AE mechanism housed in the video camera
automatically selects the speed of the electronic
shutter depending on the lighting.
Simultaneously, the
amplifier gain in the camera instead of the lens
aperture (iris) value is likewise automatically adjusted
according to the pre-selected shutter speed to obtain
the most appropriate video signal level.
(8) Lenses
Generally, there are many kind of lenses for the video
camera on the market, for example, different aperture
(iris), different focal distance, zoom lenses and so on.
Those having a shorter focal distance are called "wide-
angle" lenses, and those having a longer focal distance
are called "telephoto".
Lenses of different focal
distances have special characteristics and you can take
advantage of these in shooting.
When the camera is
fitted with a zoom lens, it is extremely easy to vary
the focal distance.
Anyhow, make choice of the most
appropriate lens for your application or system.
