The YH19x6.7 KTS is a 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 three ½-inch remote control lenses
that collectively offer an unusually broad range
of creative options.
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 YH19x6.7 KTS utilized breakthrough
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 the expressed creative desires of
producers for a truly versatile SD acquisition
system.
The YH19x6.7B represents a magnificent compromise
between the demands for mobility in a handheld
SDTV camera 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.
