The YJ13x6 KTS is a 2/3-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
2/3-inch SD remote control lenses that collectively
offer an unusually broad range of creative options.
The YJ13x6B KTS utilized breakthrough technologies
and powerful computer-aided design techniques
to produce a very wide-angle SDTV lens in a 3.73
lb package, an impressive 13% lighter than its
predecessor, the YJ12x6.5B KTS. It is a design
directly responding to the expressed creative
desires of producers for a truly versatile SD
acquisition system.
The YJ13x6B KTS represents a magnificent compromise
between the demands for compact sized, light-weight
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.
Combination of specialized materials,
contemporary optical design, and multilayer coatings
that produce the superb overall imagery
Internal Focus – a Canon design innovation
that uses a floating optical system to better control
chromatic aberrations and reduce focus breathing effects
