True HD Image Quality...

Because Professional Standard is Canon's Standard.

Genuine Canon 20x HD L Series Zoom Lens

HD image quality starts

with optics, and the XH G1

and XH A1 deliver the many benefits

of Canon's world-renowned lens

technologies. The Genuine Canon 20x

HD video zoom lens is a professional

L Series lens, incorporating Fluorite

and Ultra-Low-Dispersion elements. This state-of-the-art design

ensures outstanding resolution, contrast, and color reproduction,

delivering image quality throughout the entire zoom range unmatched

by conventional optics. The 20x zoom covers an exceptionally wide

and useful range of focal lengths—from 32.5–650mm (35mm

photography equivalent), an optional 0.8x HD Wide Angle Adapter

is available—assuring unmatched versatility for a wide range of

shooting applications.

Three 1/3" Native 16:9 CCDs (1440 x 1080)

A sophisticated 3CCD design employs sepa-

rate native 16:9 sensors for each primary

color. With 1.67 million pixels (1440 x 1080)

per sensor, the effective pixel count of the

XH G1 and XH A1 is significantly higher than

that of comparable HD camcorders. Canon's

superior design thus delivers outstanding picture quality at 1080

HD resolution. It further ensures highly accurate color with wide

dynamic range and virtually no color noise.

DIGIC DV II HD Image Processor

Engineered and manufactured by Canon,

the DIGIC Digital Signal Processing chip

(DSP) uses proprietary algorithms and architecture

to deliver the highest image quality at the highest

operating speeds. The latest-generation DIGIC DV II

HD Processor is designed for HD video, operating

at 1440 x 1080 pixels with 4:2:2 color sampling. A new hybrid

noise reduction system uses dual processes to improve image

clarity in monotone and shadow areas. Color reproduction has

also been improved, especially in skin tone areas and with dark

and light scenes. The DSP also enables high-quality still image

recording in either video or digital camera color spaces.

without Super-Range Optical Image Stabilizer

Super-Range Optical Image Stabilization

Canon's Optical Image Stabilization (OIS) uses a

gyro sensor to detect camera movement and acti-

vate the Lens Shift System to continuously compensate for

shake and jitter. The 20x HD video zoom lens on the XH G1

and XH A1 incorporates Canon's Super-Range IS Technology,

which further improves low-frequency vibration control by

using two detection methods (gyro and vector). The image at

the CCD sensor is analyzed, providing additional feedback

to the lens shift element for even greater compensation and

precision. The result is highly reliable camera shake correction, even

at long focal lengths, without any image degradation.

Comprehensive Focus and Zoom Control

The Focus, Zoom, and Manual Iris Rings provide the "feel" of a

professional broadcast lens. It allows fine, smooth adjustment in

1/8th-stop increments manually. The XH G1 and XH A1 provide

superb response, enabling zoom speed control by varying the

angle of rotation of the zoom ring with a High-Speed Zoom Mode.

Zoom speed can be variable or constant with 16 possible speed

level settings. Programmable lens presets enable repetitive focus

and zoom actions to be memorized for instant recall.

True HD 1080 Capture with Choice of

Frame Rates

The XH G1 and XH A1 capture true 1080 High-Definition video, pro-

viding images of stunning clarity. Moreover, the frame rate is selectable:

Capture and output video in 60i, 30F, or 24F as needed to deliver

spectacular clarity or evoke the look and feel of film and episodic TV. A

50i/25F option is available, requiring modification at a Canon Service

Center. Modified cameras offer the option of switching to 50i or 60i

capture in HD mode and PAL or NTSC compatibility in SD modes.

Built-In Neutral Density Filters

Two built-in Neutral Density (ND) filters (1/6 and 1/32) reduce expo-

sure by two or five stops for added image control. They can be used,

for example, when shooting bright, sunlit exteriors or to decrease

depth of field for a more dramatic, cinematic look. A focus distance

readout in the viewfinder assists in setting manual focus.

Instant AF

Instant AF is Canon's next-genera-

tion autofocus technology. A new

external sensor works in combi-

nation with Canon's proven high-

performance internal AF system

to dramatically reduce focusing time and increasing

accuracy, even in low-light or high brightness situa-

tions. Focusing performance is also much improved with difficult

subjects. The high resolution of HD video makes focus more critical

than ever, and Canon's Instant AF helps videographers capture HD

images with expert precision.
