Canon Technologies Raise the Standard

Genuine Canon

Video Lens

Image quality starts with optics, and only

Canon professional camcorders deliver

the many benefits of Canon's world-

renowned lens technologies. Genuine

Canon Professional L-series camcorder

lenses incorporate Fluorite and Ultra-Low-

Dispersion elements plus SR multi-coating

to ensure outstanding resolution and

contrast with minimal chromatic aberration.

The choice of professionals the world over,

Canon L-series lenses deliver a level of image

quality throughout the entire zoom range

unmatched by conventional optics. The

standard 20x zoom covers an exceptionally

wide and useful range of focal lengths,

perfect for a wide range of shooting

situations.

Fast, Responsive Zoom Control

With an ergonomically designed ring shape

and increased speed, the zoom control on

Canon professional camcorders starts and

stops with exceptional smoothness and

provides a comprehensive array of options.

The zoom can be controlled in 3 different

ways – the lens zoom

ring, grip zoom lever

or handle zoom lever

(for low-angle shots).

Select from among

3 basic zoom speed

ranges and fine-tune

the zooming with 16

levels of speed control.

With the Genuine

Canon 20x HD Video

Zoom Lens, zooms from wide to tele range

can be varied in speed from 5 minutes to

an astounding 1.2 seconds at the fastest

setting. Variable zoom speed operation with

16 levels of speed control is also possible

through the pressure-sensitive zoom lever

SLOW

Approx. 4.3 sec. (speed: 16x) to approx. 5 min. (speed: 1x)

NORMAL

Approx. 2.0 sec. (speed: 16x) to approx. 3 min. (speed: 1x)

FAST

Approx. 1.2 sec. (speed: 16x) to approx. 60 sec. (speed: 1x)

Zoom speed can be set to NORMAL, SLOW or FAST via C.Fn-02

(rocker). Or choose from one of the 16 levels

and preset it to perform constant pace

zooms. Starting and stopping of zoom

movement is always ramped to avoid

"zoom shock" and provide a more natural,

pleasing look to your footage.

Precise, Flexible Focus Control

HD capture demands precise focus. The

highly responsive, independently function-

ing focus ring (with selectable operational

direction) enables the videographer to

focus manually even while zooming – in

both Manual Focus and AF modes. There

are 4 selectable preset focus speeds along

with 3 sensitivity settings for the focus

ring, making it possible to fine-adjust

responsiveness as

desired. Push AF

control enables

temporary manual

override to quickly

find critical focus,

while a Focus Limit

function can be

engaged to limit the focusing range of the

lens, for example, for macro shooting.

Dedicated Peaking and Magnifying controls

are available to further assist in focusing.
