DIGISUPER 22xs
HD Compact Studio Lens
About 1 / 3 the Weight of Standard Studio Lenses.
Responding to increasing use of portable HD
cameras in studios, Canon invented the
entirely new product category of the HD
Compact Studio Lens with the introduction of
the DIGISUPER 22xs (model XJ22x7.3B IE-D).
Scaled for Portable HD Cameras
The perfect complement to portable HD
cameras configured for studio use, the
DIGISUPER 22xs is engineered to be compact
and lightweight.
Superb HD Optical Performance
The DIGISUPER 22xs offers higher contrast
and resolution compared with portable HD
lenses, but at the same time reduces Focus
Breathing to a zero level.
Studio Operation
By adopting an "Encoder Servo System," the
maximum servo speed has been improved to
Zoom: 0.5 sec., Focus: 1.5 sec. Also, the
DIGISUPER 22xs HD Compact Studio Lens'
new encoder system enables it to be easily
integrated into virtual studio applications.
Status at a Glance
The DIGISUPER 22xs is equipped with an informational display, which
enables the easy and precise use of diverse digital functions.
Controllability
The DIGISUPER 22xs can be used with Canon's current Studio/Field lens
controllers as well as those for Canon ENG lenses. The DIGISUPER 22xs
HD Compact Studio Lens also offers compatibility with our new digital
demands by use of a conversion cable.

DIGISUPER 27
The DIGISUPER 27
and DIGISUPER 27AF
HD studio lenses (models
XJ27x6.5B and XJ27x6.5B AF,
respectively) deliver unprecedented performance for HD studio
production applications. Both provide the widest angle of any lenses
available, a focal length (zoom ratio) of 6.5mm to 180mm, and newly
developed multi-layer optical coatings that dramatically reduce
ghosting and flaring. Both also offer Canon's optional BWA-271 0.9x
Wide Attachment, the industry's first wide-angle attachment for an HD
studio lens. This "zoom-through" Wide Attachment enables users to
begin with a wide shot and go telephoto without compromising light
transmission. This feature alters the range of the zoom on wide
settings by ten percent toward the wide side, making a new zoom
range of 5.85mm to 162mm.
Other innovations in the DIGISUPER 27 and DIGISUPER 27AF HD
studio lenses include a servo-zoom speed of 0.5 seconds and a
new optional remote-controllable macro-focus feature that allows
the camera operator to perform macro focusing from the pan bar
(a helpful tool for focusing on jewelry and other small objects).
Auto Focus Optimized for the HD Studio
The DIGISUPER 27AF HD studio lens delivers the benefits of
Canon's Auto Focus technology to the HD studio environment.
Utilizing sophisticated Auto Focus capabilities based on a
proprietary HD implementation of Through-the-Lens Secondary
Image Registration Phase Detection Method technology, the
DIGISUPER 27AF HD lens is optimized for studio use. The
tremendous picture detail contained in HDTV makes anything in
less-than-perfect focus immediately obvious. The DIGISUPER 27AF
HD studio lens assists camera operators in ensuring that sharpest
focus on a chosen scene subject is achieved each and every time.
