Fluorite Zoom Lens with Optical Image Stabilization
Canon has satised the demands of experienced image makers for years through the power,
design and quality of 35mm and broadcast TV lenses. Canon continues that tradition with the new
20x Professional L-Series Fluorite optical zoom lens for the XL2. The lens uses uorite, a material
that provides outstanding resolution, contrast, and color reproduction, especially in lightweight,
high-magnication lenses. The uorite element inside the lens defeats color aberration an effect
that causes a reduction in sharpness, contrast and color. It precisely controls components of light
providing an excellent balance of these three critical ingredients of picture quality. The unsurpassed
image quality is unobtainable with conventional optical glass.
The XL2’s lens is the equivalent of a 42.3mm -- 846mm
lens on a 35mm still camera, when the XL2 is recording
in 16:9 widescreen format. When recording video in the
TV-standard 4:3 aspect ratio, it is the equivalent of a
51.8mm -- 1036mm lens on a 35mm still camera.
In addition, the XL2 features Canon’s superb Super
Range Optical Image Stabilization (OIS) system (VAP
type). The system corrects camera shake instantly so
that even hand held shots at full telephoto and shots taken from a moving car are smooth and steady.
Previously, optical image stabilizers have used a gyro sensor to detect camcorder vibration. The data
from the sensor would control a vari-angle prism that continuously corrected the path of the incoming
light. Super Range goes one step further by examining the image after it is received by the CCD to
detect any low-frequency vibrations missed by the gyro. This data is fed back to accelerate and rene
the movement of the vari-angle prism. This greatly improves performance for low frequency vibration,
resulting in the most advanced optical image stabilization available today.
And since the XL2’s OIS system is optical, there isn’t the loss of image quality that is inevitable with
electronic image stabilizers. It perfectly complements the high picture quality of the DV format.
f/1.6 - f/3.5
Canon’s 20x Professional L-Series Fluorite lens features a fast aperture of f/1.6, variable to f/3.5 at
full telephoto. This maximum aperture of f/1.6 aids in capturing quality video in low light conditions.
72mm lter thread
With a standard 72mm lter thread, the 20x Professional L-Series Fluorite lens offers the availability
of a wide variety of lters from Canon and other suppliers.
6 blade iris diaphragm
A six-blade circular iris is used in the XL2 for professional exposure control. This helps to deliver
stunning video and still photos.
