The XH G1 and XH A1 High Definition camcorders reflect
decades of Canon leadership and know-how in the design
and manufacture of cameras and lenses for professional
video and still photography. Videographers get not only outstanding HD image quality but
also the operability, flexibility, reliability, and connectivity that professionals demand of
their gear. The Canon XH G1 and XH A1 deliver the technologies, performance, and features
that make them serious tools for the capture of creative HD content. Put them to work.
They’ll help videographers get the job done with efficiency, excellence, and expression.

Super-Range Optical Image Stabilization

Canon’s Optical Image Stabilization (OIS) uses a
gyro sensor to detect camera movement and acti­vate 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, pro­viding 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 lookand 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 expo­sure 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-genera­tion autofocus technology. A new
external sensor works in combi­nation with Canon’s proven high­performance internal AF system
to dramatically reduce focusing time and increasing
accuracy, even in low-light or high brightness situa­tions. 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.

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 sepa­rate 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.
