The XF305 and XF300 HD Camcorders feature a stunning Genuine Canon 18x HD L-Series video lens 
designed to capture images with superb clarity, and capable of delivering 1,000 TV lines of resolution. 
With a 35mm equivalent zoom range of 29.3–527.4mm, the lens is perfect for virtually everything from 
wide-angle to extreme telephoto shooting. As with the legendary Canon EF L-Series camera lenses, 
this HD L-Series video lens uses advanced optical design and technology. It incorporates High-Index-
Ultra-Low Dispersion (HI-UD), UD and aspherical lens elements to capture high-resolution video while 
minimizing chromatic aberration. Precise and predictable lens operation is achieved with mechanical 
end stops for both zoom and focus systems. Additionally, the lens barrel includes distance indicators 
for easily setting focus distance or moving between focus points while recording.

The feature-rich XF205 and XF200 camcorders, together with the ultra-compact XA25 and XA20 
models, feature a highly versatile Genuine Canon 20x HD Video Lens that captures superb images 
with outstanding clarity at 900 TV lines of resolution. Offering a 35mm equivalent zoom range of 
26.8–576mm (range is 28.8–576mm with Dynamic IS on), the lens provides an extended zoom range 
optimized for both wide-angle and extreme telephoto shooting. And its flexible focal range and 
enhanced wide angle offer many creative options, even when working at a distance. An 8-blade 
circular aperture provides more natural and visually pleasing bokeh. In addition, both the XF205 and 
XF200 camcorders feature three separate rings on the lens for independent control of critical Focus, 
Zoom and Iris/Aperture settings.

The compact XF105, XF100 and XA10 camcorders feature a meticulously engineered Genuine Canon 10x 
HD Video Lens that helps enable stunning HD capture. With a 35mm equivalent of 30.4–304mm, the lens 
provides a versatile zoom range that can be extended with optional Canon wide-angle or teleconverter 
lenses. Close-focusing capability is maintained throughout the entire zoom range, and a maximum 
aperture of f/1.8 enhances acquisition capability in low-light conditions. The lens provides a manual focus 
ring that can be used at any time, even during AF operation. 

Engineered and manufactured entirely by Canon, the CMOS image sensors employed in the XF305/XF300, 
XF205/XF200, XF105/XF100, XA25/XA20 and XA10 feature 1920 x 1080 resolution to ensure Full HD video 
recording with wide dynamic range and low noise. Both the 1/3-inch sensor size of the XF305, XF300, 
XF105, XF100 and XA10 camcorders, and the 1/2.84-inch sensor of the XF205, XF200, XA25 and XA20 
camcorders enable a compact lens and body design for greater shooting versatility. The XF305 and XF300 
use three CMOS image sensors for optimal color purity and accuracy. 

Designed specifically for Canon HD camcorders, 

 DV Image Processors provide brilliant clarity 

and superb processing power for advanced image stabilization technologies. The 

 DV III Image 

Processor helps ensure natural, life-like colors with excellent black reproduction. Tonal gradations and 
shadow details are captured with remarkable accuracy, and it helps enable Genuine Canon Face 
Detection, which is ideal for tracking a face in a crowd. The 

 DV 4 Image Processor builds upon 

these features, improving low-light shooting and ramping up processing power to allow simultaneous 
recording in MP4 and AVCHD – with both possible at 1080/60p.

The XF Series camcorders use Material Exchange Format (MXF). MXF, an internationally standardized 
file format, is designed to make the exchange of audio and video materials among NLE (Non-Linear 
Editing) systems simple. The MXF format wraps video and audio with metadata in a single file, 
maintaining access to critical information throughout the production process.

The XF Series camcorders record stunning images using the Canon XF Codec, which captures Full HD 
(1920 x 1080) at a maximum constant bit rate of 50 Mbps with 4:2:2 color sampling and industry-standard 
MPEG-2 compression. 4:2:2 sampling delivers twice the color resolution of HDV and other 4:2:0 
codecs, helping to ensure ultra-fine tonal transitions through post-production processes. This makes 
the Canon XF Series camcorders an excellent choice when advanced post-production techniques, such 
as compositing, color correction or grading, are required. The 50 Mbps bit rate provides the high 
bandwidth needed to deliver outstanding color rendition and image detail. The use of highly reliable 
and versatile MPEG-2 compression helps to assure the widest compatibility with existing infrastructure, 
including non-linear editing (NLE) systems (Adobe®, Apple®, Avid® and Grass Valley®). XF Series camcorders 
can be easily integrated with established workflows, such as those of terrestrial broadcasting, and 
cable and satellite television networks.
