Canon's optical expertise is clearly seen in the XF105's Genuine Canon 10x HD Video Lens. It delivers flexibility in image capture with a zoom range of 30.4 – 304mm (35mm equivalent).
Power zoom is available in Constant and Variable settings in 3 modes, Fast (approx. 1.9 – 60 seconds), Normal (approx. 3.0 – 180 seconds) and Slow (approx. 4.0 – 285 seconds). To provide added control, there are 16 predefined steps in Constant mode and rocker switch pressure sensitive or control ring speed management in Variable mode.
For enhanced versatility the XF105 offers a built-in gradation type neutral density (ND) filter (approximately 1/8), as well as an eight blade metal aperture iris.
A customizable manual control ring allows users to assign focus, zoom, or iris. These functions are easily selected through a switch on the lens barrel.
Additionally, a custom dial is available which allows the iris to be controlled.
SuperRange Optical Image Stabilizer
The XF105 also incorporates a SuperRange Optical Image Stabilization system (lens shift) with four modes: Standard, Powered, Dynamic and Off.
Lens shift is controlled so that the maximum compensation angle is constant from wide angle through telephoto.
Vibration is suppressed at the telephoto end of the range, where shake is most apparent due to high magnification.
Stabilization changes throughout the zoom range to minimize more pronounced shaking. This is especially useful at wide-angle focal lengths when walking.
When shooting high definition video, sharp focus becomes more critical than ever. Canon's proprietary Instant AF system combines an external AF sensor with Canon's legendary auto focus system for fast and accurate focus. Together, the two sensors reduce focusing time - even in low-light, low contrast, or high brightness situations - and improve focusing performance on difficult subjects.
The XF105 gives you a choice of five AF modes for different shooting applications:
Instant AF changes focus as rapidly as possible, for those applications in which quick focus is more important than other considerations - for example, in news gathering or documentary work.
Medium AF changes focus at a speed which is softer and smoother than Instant AF, but faster than would likely be possible manually.
Normal AF changes focus at a speed that appears natural and doesn't distract the viewer.
Face AF tracks focus on faces when present. The user selects the face to be tracked. Face AF has the ability to track even if the subject face is in profile. If the chosen tracked face is not present in a shot, the subject in the center of the screen will automatically be brought into focus.
Face Only AF automatically tracks the chosen tracked face in focus but, should that face leave the scene, will reset focus to manual mode.
Minimum Object Distance
When shooting with the XF105, the minimum focus distance is 20mm (0.78 inches) at Macro and maintains 60cm (1.97 feet) throughout the entire zoom range. This allows excellent versatility in a wide range of shooting situations.
In contrast to a typical 6-blade iris, the XF105's 8-blade iris captures extraordinarily smooth out-of-focus ‘bokeh' for a more attractive image effect. The additional blades also reduce diffraction of light passing through the iris, allowing for the use of smaller apertures while maintaining image quality.
The Digital Teleconverter extends the reach of the optical zoom, and is selectable by 1.5x, 3x and 6x. This feature is ideal when extreme telephoto shooting is needed such as in sports and wildlife, as well as surveillance applications for law enforcement and the military.
