Superb performance in 1/3 inch HDTV lens series

KT17ex4.3B

Canon’s Philosophy :

Canon has always developed new technology with four basic philosophies, "High Quality of Picture", "Ease

of Operation", "High Specifi cation" and "Minimize Environmental Impact". Canon's HDTV lenses are, so

to speak, a compilation of our basic philosophies. Now, Canon reassembles these philosophies in the

launching of a second generation HDgc lens series.

KT17ex4.3B

Superb performance in 1/3 inch HDTV lens series

The recent expansion of HDTV broadcasting has seen the range of HD

camcorders with interchangeable lenses increasingly encompass the

1/3-inch image format size. This format size offers a more compact,

mobile, and cost effective HD acquisition system. In support of these

1/3-inch systems, Canon had earlier released two lenses – the KT20x5B

high-performance model and the KT14x4.4B KRS multipurpose model.

They have proven popular in cost-effective HD program origination. Now Canon

introduces a new 1/3-inch lens specifically tailored to HD ENG and lower-budget

HD production. The KT17ex4.3B IRSE offers a modest wide-angle  eld of view, and

generous focal range that is further augmented with a 2x extender.

Main Features

Excellent operational performance with 2x extender and ergonomic

Digital Drive unit

To meet the fl exible shooting needs of broadcast News and General HD production, it is desirable

that the lens combine high optical performance with rich operational features. The KT17ex4.3B

IRSE lens was designed to squarely meet these requirements. High attention to overall optical

performance is allied with excellent optomechanical ruggedness, an ergonomic digital drive unit

identical to that used in the highest-end Canon lenses, and the all-important 2x extender.

Outstanding Optical Performance

Canon mobilized the best in optical design and optical materials to produce a lens worthy of the

best in contemporary 1/3-inch camera systems. Advanced optical and optomechanical design

have produced a remarkably compact and lightweight lens. The KT17ex4.3B IRSE deploys large

aspheric lens elements design to enhance corner resolution while tightly controlling comatic

aberration and geometric distortion. A range of optical glass elements include the use of Fluorite

and Hi-UD glasses identical to those used in the high-end HD lenses. Lens contrast is extended,

flare and veiling glare reduced, chromatic aberration is lowered, center and corner resolution

elevated – all combining to produce a signifi cant enhancement to overall picture sharpness.

Improved Operability and Reduced Operator Fatigue

Coupled with innovations in optical performance, is a totally new design of the digital drive unit.

Refi ned by long-term market research and worldwide experience, Canon utilized the latest in 3D

CAD-CAM design to signifi cantly improve the human tactile interface to the control of zoom, iris,

and focus. Canon’s research produced the following physical enhancements:

Reduced Physical Stress Ergonomic DesignImproved Ease of Operation

The size and curvature size have been optimized to

more comfortably fit in the palm of the operator’s

hand(a). Newly developed coatings improve the

tactile interface between the user and the drive unit

(b) together with the new Rubber Grip Support (c).

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.

The spacing between the focus ring and drive unit

has been opened to avoid accidental interference

with the drive unit while manipulating the focus

control.

Enhanced Digital Drive Unit

With the introduction of miniature 16-bit high resolution

Rotary Encoder Devices into the enhanced digital drive

unit, the lens features;

• Superior precision lens control.

•

Precise repeatability in zoom, focus and iris control which

supports the creative digital operational functions.

•Simple integration into virtual digital studio systems

without any options.

•Dynamic zoom speed range of 0.5 sec. to over a 5

min. super slow zoom.

Moreover, Canon’s original Information Display is able

to customize the enhanced digital functions much more

easily and precisely.

Enhanced Digital Functions

Shuttle Shot

By memorizing any two focal lengths, the Digital

Drive can automatically "shuttle" between the two

points, moving in either direction.

Frame Preset

An angle of view can be preset in either of two

memories and the lens will zoom at the highest speed

or in a preset zoom speed to the preset position by

pushing a simple button.

Speed Preset

A specifi c zoom speed can be preset in memory and it

is possible to repeat the zoom speed as often as you

like by pushing a simple button.
