Canon HJ14ex4.3B Specifications page 2

Widest Angle Lens To Date in the TV Industry
With a minimum focal length of 4.3mm the HJ14ex4.3 lens features the widest angle among
presently available 2/3-inch lenses with an angular field of view of 96.3 in the 16:9 format at the
wide end. This is significantly augmented with the 14x zoom range reaching to 60mm (120mm
with extender), producing an unsurpassed operational combination that greatly expands HDTV
production applications.
Improved Optical Performance
The past decade has seen dramatic advances in powerful new 3D optical design tools, glass
materials, design techniques (such as aspherical elements), and optical coatings. These new
technologies allow the HJ14x lens to provide a wider angle and a higher zoom ratio than previous
models, while also offering important optical performance enhancements:
Higher resolution at both picture center and at the extremities of the 16:9 HD image plane
Further minimization of chromatic aberrations and geometric distortion
Less light falloff from picture center to corners, especially at wide angle settings
Reduced focus breathing
Curtailment of ghosting artifacts created by strong light sources
Improved Operability & Reduced Operator Fatigue
Coupled with innovations in optical performance, is a totally new design of the digital drive unit.
Refined by long-term market research and worldwide experience, Canon mobilized the latest in
3D CAD-CAM design to significantly improve the human tactile interface to the control of zoom,
iris, and focus. Here are some results of Canon's research:
Reduced Physical Stress
By reducing the width of the drive unit, the palm of
the camera operator's hand is positioned closer to
the optical axis, thus reducing the degree of arm
bend which in turn lessens physical stress during
prolonged shooting.
Smaller Hood Size and Higher Versatility
The HJ14ex4.3 uses a smaller hood unit compared to it's
predecessor. While increasing the versatility of the camera,
this also helps the camera operator view the actual scene.
Over the past decade, as the demand for broadcast HDTV production has continued its
steady growth, Canon's HJ11ex4.7B lens has been a popular HDTV wide-angle lens,
earning a stellar global reputation for outstanding optical performance and ease of
operation. Capitalizing on this legacy of imaging excellence, Canon is expanding the
possibilities of HDTV origination with the launch of an even more advanced wide-angle
lens, the HJ14ex4.3B. This is a totally new-generation lens design and is particularly
innovative in combining an extended 14 times zoom range and unprecedented 4.3mm
wide angle, with an enhanced overall optical performance. Unequalled image clarity and
sharpness were the design goals.
Even the digital drive-unit is newly developed to provide streamlined ergonomics and
ease of operation that further empowers camera operator shooting flexibility.
Ergonomic Design
The spacing between the focus ring and drive unit
has been changed to avoid accidental interference
with the drive unit while manipulating the focus
control.
