The YH16x7 KTS-AF is ½-inch
wide angle of view portable lens offered by Canon
to support diverse remote imaging applications
including teleconferencing, distance learning,
and specialized broadcasting applications. It
is a member of a family of four ½-inch
SD remote control lenses that collectively offer
an unusually broad range of creative options.
It is unique in being equipped with an exclusive
built-in automatic focusing system that analyzes
the camera video signal and focuses the lens on
a scene object of choice.
This particular lens is intended
for producers and broadcasters having as their
foremost priority wide angle shooting with a lightweight
mobile production lens-camera system that offers
exceptional SDTV performance.
The YH16x7 KTS-AF utilized advanced
technologies and powerful computer-aided design
techniques to produce a very wide-angle SDTV lens
in a modest 4.3 lb package. It is a design directly
responding to expressed creative desires for a
truly versatile SD acquisition system.
The YH16x7 KTS-AF represents an excellent compromise
between the demands for compactness and lightweight
in a remote controlled acquisition system and
the exacting performance requirements for high-end
SDTV production. The requisite optimization strategies
to achieve this balance sought a high MTF over
the entire image plane, minimization of chromatic
aberrations, and maximization of image contrast.
Preservation of the highest MTF at the wider angle
focal lengths (where scene detail can be particularly
high) was a special priority.
