The New Genuine Canon 20x HD Video Zoom Lens III with Professional L Series
Genuine Canon 20x HD Video Zoom Lens III

In a world where format technologies are constantly evolving, one of the most important components is the lens. Canon is known as a high-end optics company, first and foremost. Canon lenses are indisputably among the very best in the world. At the end of the day, it doesn't really matter what technological magic is happening behind the lens, or what creative genius is unfolding in front of it, for that matter, if the glass through which the light is passing is not manufactured to the very highest of standards.

The standard lens of the XL H1A brings features which give the user unprecedented control over zoom, focus and iris settings, delivering an even higher level of creative expression. Clearly identified by the black finish and red stripe around the front element, this Genuine Canon 20x Video Zoom Lens III with Professional L Series Fluorite is a part of Canon's professional quality lenses. The 20x HD fluorite lens features an SR multi-coating which minimizes ghosting and veiling of the image, and ensures the highest level of resolution and color fidelity. The focal length range of the standard lens is equivalent to 5.4 to 108mm (in 35mm photography terms).

Interchangeability and the XL Mount
INTERCHANGEABILITY AND THE
XL MOUNT:
One of the most useful and desirable features that distinguishes the XL line of camcorders is the interchangeable lens system. This flexibility of optics opens the door to total creative freedom, which is further enhanced by adaptors that are available for the camera's XL mount. The EF Adapter, for example, will allow you to use any of the Canon still-camera lenses in the EF series. Keep in mind that these lenses were designed for a larger target area, so there will be a 7.2x magnification (in 16:9 aspect ratio shooting) when using them on the XL H1A. Thus, a 100mm lens will become a 720mm lens. Certainly, this is ideal for any long-lens photography that your project may require.

72MM FILTER THREAD: Any filters with the 72mm thread size can be screwed directly on the front of the lens, even with the lens hood attached.

INDEPENDENT MANUAL FOCUS, ZOOM AND IRIS RING: This new lens brings the highest levels yet of focus, zoom and iris control, in a redesigned system made for ease of operation and a wide range of control.

MANUAL FOCUS RING: Increased weighting of the ring also provides smoother control, along with smooth zoom start and stop to eliminate any choppiness in the shot. Select from three settings, High-, Normal- and Low-speed, on the more responsive manual zoom ring. The response of the focus ring is also selectable, with Slow, Normal or Fast options. To further add to the level of choice, the rotational angle of the zoom, between Wide and Tele is selectable. Choose 45°, 60°, or 90°, depending on your needs. You may also use manual focus during the zoom whether you are in Manual Focus or AF Mode.

NEUTRAL DENSITY FILTER RING: With the push of a button and a counterclockwise turn, you can activate either of the two neutral density filters. The 1/6 option takes down the exposure by 2 1/2 stops, while the 1/32 option reduces the light intake by 5 stops. There are two primary reasons why you would want to employ these filter options: practical necessity and aesthetic choice.

Helpful Hint: Oftentimes, if you're shooting in bright, sunlit exteriors, you'll need to engage an ND filter in order to get a proper exposure. In normal operation, the lens itself only stops down to F9.5 before closing. This is to prevent diffraction, but you can override this by turning off the iris limit control. If this is inadequate, and the image still looks overexposed, then the neutral density filters will bring the brightness down to a more manageable level.

IRIS RING: An extremely useful function on the XL H1A is the manual iris adjustment ring. It allows you to adjust your f-stop with the same hand and in the same manner as you focus and zoom. You can thereby control all aspects of the image with your fingertips, while keeping the camcorder steady.

OPTICAL IMAGE STABILIZER: Along with the high-quality optics and the interchangeability of the lens, this feature is the third big reason to love the Canon XL H1A. The Canon system delivers a superior optical solution that does not degrade the image in any way. Unlike electronic image stabilizers that reduce jitter by digitally moving the image, the Canon lens features a gyro sensor that detects motion and continuously adjusts the vari-angle prism to eliminate jitter and shake. Super Range technology then re-examines the image after it's been received by the CCD and sends additional information to the vari-angle prism that further refines its movements, thereby enhancing the "smoothing" ability of the stabilizer. As a result of this advanced interactive process, your shots will be much more graceful and controlled, even when using maximum zoom in your shot.


Helpful Hint: It is recommended that you test in your shooting situation when using the camera on a tripod or a similarly controlled head to decide whether to keep the stabilizer turned on. Under these circumstances, the stabilizer may overcompensate for the already smooth moves that you are making.

POSITION PRESET: This feature allows you to set either a focus point or a specific focal length, and then execute a "rack-focus" or a "zoom" to that pre-selected point during the shot. For example, if you want a distinct rack focus effect, you would first switch the "Position Preset" slider from "Off" to "Focus". Then, eye-focus on whatever part of the frame you want to have in focus at the end of the shot. Slide the bar labeled "On/Set" (beneath the "Position Preset" control) to "Set". Now you're ready to begin your shot. Focus on anything else in the frame that you need to, and when you want the rack-focus effect to kick in, simply slide the "On/Set" bar in the "On" direction. This can be done repeatedly over multiple takes; the "end-point" for the focus is saved until you set a new value, or until you switch the "Position Preset" bar to "Off". You can select the speed of the rack focus (high, medium, or low) in the CAMERA SETUP page of the menu.

The same process applies for setting a zoom effect. Instead of racking focus, however, the lens will zoom to the desired focal length when the "On/Set" bar is slid in the "On" direction. You can select the speed by using the main zoom handle controls on the camera body. Set the zoom to "constant" mode and use the "Fast/Slow" toggle to find the desired value (from 1 to 16). Whatever speed you select in the "Constant" mode will determine the speed of the "Preset" zoom effect, even if you switch the main controller to "Variable". If you keep the main control on "Constant", however, you can actually adjust the speed during the zoom by using the "fast/slow" toggle.

Helpful Hint: These presets are useful even if you're not looking for a specific rack focus or zoom effect. If you're doing a "talking head" interview, for example, you may want to get a solid eye-focus on your subject, and then lock that focus point into the preset. Now you're ready for anything; if you have to pan away to grab another detail that may require a focus adjustment, you can be confident that when you return to your subject, you can hit the preset slider and return to the precise focus point without worry.

AF/MF (Auto Focus/Manual Focus)
AF/MF (AUTO FOCUS/MANUAL FOCUS):
You can choose Auto Focus or Manual Focus on the lens itself, regardless of which mode the camera is in. In other words, even if you're in "Manual" mode, you can set the lens to "Auto Focus". Similarly, even in "Auto" mode, you can set the lens to "Manual Focus". The only exception will occur if the "Green Box" mode is selected on the camera body, in which case the lens will be placed into "Auto Focus" by default, even if "Manual" is selected.

If you are in "Manual Focus" but find yourself in a situation where you need a little help from the lens, you can use the "On/Set" slider control that is directly above the "AF/MF" switch. By moving this slider to the right, you will temporarily activate the "Auto Focus" mode until the slider is released. The focus will then revert back to the "Manual" mode.

DISTANCE DISPLAY: The lens provides a subject-distance read-out in your viewfinder. This function gives you the same, useful subject distance information you get from reading the markings on the barrel of a front focusing lens.

MOD (MINIMUM OBJECT DISTANCE) FUNCTION: The lens includes a Minimum Object Distance (MOD) feature, which creates an auto focus range suitable for normal shooting situations from one meter to infinity. This feature prevents the lens from focusing on dust particles that can occasionally appear on the surface of the lens. For macro applications, the AF range can be extended to a minimum focusing distance of 20mm.

FOCUS PRESET FUNCTION: The focus preset function lets you manually focus on your subject, then store that information in memory. Once the focus is set, you can then capture shots in which you change your focus from infinity (or some other distance) to your subject -- using three different settings.

ZOOM PRESET FUNCTION: The zoom preset function lets you preset the focal length of your lens, and then store that information in memory. This feature is useful when you want to preset a focal length for the end of a shot -- for example, when you want to zoom in on your subject.

ONE-PUSH AF FUNCTION: The one-push AF function is used when you want to fix the focus on a particular subject using AF. This feature is very helpful, for example, when you are tracking a specific person in a shot that includes many people moving in different directions.

(2) BUILT-IN ND FILTERS: The built-in ND filter lets you select one of two neutral density levels (1/6, 1/32), giving you the flexibility to obtain optimal results under a wide variety of lighting conditions. An ND warning display even alerts you to bright conditions that can result in the deterioration of image quality.
