Exceptional Image Quality
Only Canon Can Deliver
Genuine Canon 20x HD Video Zoom Lens III
The XL H1S and XL H1A have all the advantages of Canon's
proven leadership in optical technology and optics drive HD
image quality. The interchangeable Genuine Canon 20x HD Video Zoom Lens III (35mm
equivalent 38.9–778mm) is a new high-performance L-series lens, specifically designed for HD
production. Now in its third iteration, this redesigned lens incorporates two aspherical lenses,
Canon's world-renowned fluorite glass and SR multi-coating technologies that produce superior image
quality with excellent resolution, contrast and minimal chromatic aberration. The L-series designation that is
identified by the distinctive red ring has become the symbol of professional lenses worldwide for its unmatched
reputation as the choice of industry professionals the world over. The lens also features a new manual iris
ring in 1/16-stop increments for exceptional exposure control and two built-in ND (Neutral Density)
filters that reduce exposure by 1/6 (2 stops) or 1/32 (5 stops). Focus and zoom operations have also
been improved so that they allow manual focusing during zooming. Design and ergonomics have further
been improved such as a weightier zoom ring and an adjustable rotational angle for the zoom ring,
contributing to a lens feel that many professionals prefer. Lens Presets also allow the operator to store
any given focus or zoom point and return to that position with a single touch of a button.
Fast, Responsive, Versatile Zoom
With a newly designed ring shape and increased
speed, the camera's zoom starts and stops with
exceptional smoothness and provides a comprehen-
sive array of options. The zoom can be controlled in
three different ways—the lens zoom ring, grip zoom
lever or handle zoom lever (for low-angle shots). It
features three widely ranging zoom speeds, and
16 levels of speed control. With the new Genuine
Canon 20x HD Video Zoom Lens III attached, zooming
speeds from wide to tele range in speeds from 5 min-
utes to an astounding 1.2 sec. at the fastest setting.
Variable zoom speed operation with 16 levels of speed
control is also possible through the pressure-sensitive
zoom lever (rocker). Or choose from one of the 16
levels and set it so that zooming is done at a constant
pace. Furthermore, starting and stopping of zoom
movement is "ramped," avoiding "zoom shock" in
your videos or broadcasts for a more natural effect.
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
Comprehensive Focus Control
The XL H1S and XL H1A deliver HD, which demands
precise focus. The highly responsive, independ-
ently functioning focus ring (with selectable oper-
ational direction) allows the videographer to focus
manually even while zooming—in both Manual Focus
and AF mode. 4 selectable preset focus speeds
are available along with three settings of sensitivity
for the focus ring allowing you to set the respon-
siveness to your liking. Push AF control lets you
temporarily override manual focus to quickly find
critical focus, while a Focus Limit function (selec-
table to on or off) limits the focusing range of the
lens such as when shooting macro. To further assist
in focusing, dedicated Peaking and Magnifying
controls are available. For Peaking, frequency (edge
thickness) and gain (edge density) levels are
adjustable. Two settings can be stored and accessed
quickly with a touch of a button. By attaching the
included external monitor cable to the component
terminal of a monitor, the operator can also use
peaking and magnify controls to check manual focus
on a larger screen rather than in the finder.
Canon Interchangeable XL Lens Mount
The XL H1S and XL H1A feature the XL mount system
that offers the added range and flexibility of using
optional interchangeable lenses, including the wide-
angle Canon 6x HD Video
Zoom XL 3.4–20.4mm L
lens (35mm equivalent
24.5–147mm), ideal for
applications requiring a
wider field-of-view. This L-series lens captures in
Full HD clarity and incorporates all of Canon's leg-
endary optical superiority. The XL lens mount also
enables the use of the Extender XL 1.6x, which
increases the focal length
by 1.6x and the EF Adapter
XL, which enables users
to attach a wide array of
Canon photographic EF
Extender
lenses (only L-series is
XL 1.6x
recommended)—for specialized image capture.
SuperRange Optical Image Stabilizer
Steady images are ensured with Canon's
Optical Image Stabilizer. The system
continuously compensates for shake and
jitter by activating a Vari-Angle prism when the
gyroscopic sensors detect camera movement. The
XL H1S and XL H1A can correct a wide range of
vibration because the cameras' 20x HD Video Zoom
Lens III incorporates Canon's SuperRange Optical
Image Stabilizer technology to analyze the image at
the CCD sensor. The result is extraordinary camera
shake correction, even at long focal lengths.
Three 1/3" Native 16:9
CCDs (1440 x 1080)
Its sophisticated 3CCD design
gives each primary color a dedicated
native 16:9 sensor. Each sensor has
approx. 1.67 million pixels (1440 x 1080), giving
the XL H1S and XL H1A a high pixel count (equal to
800 TV lines of horizontal resolution). Color is ren-
dered with exceptional accuracy, in a wide dynamic
range and with virtually no color noise.
Canon DIGIC DV II
HD Image Processor
Engineered and
manufactured
exclusively by
Canon and specifically for HD, the latest generation
DIGIC DV II HD Image Processor delivers optimal
image quality at the highest operating speeds.
The DIGIC DV II HD Image Processor is designed for
HD, operating at 1440 x 1080 pixels with 4:2:2 color
sampling. Color reproduction is exquisitely natural,
especially in skin tones and in dark or light scenes.
A hybrid noise reduction system employs dual
processes to create brilliantly clear HD images.
