Super-Range Optical Image Stabilizer. Some image stabilization systems correct one type of camera motion or vibration better than another.
But Canon's Super-Range OIS corrects for a wide range of camcorder motion: the fast vibration you'd experience while recording from a moving car; the medium-speed motion of hand-held recording; and the slower motion of body sway. No matter what you're recording and how you're recording it, the XH A1's stabilization design corrects camcorder shake instantly.
Instant AF. With HD, focus is more critical than ever. Because HD resolution is higher, focusing time is longer -- it's harder to find perfect focus.
Canon's Instant AF 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.
Color reproducibility has also been enhanced for improved color image quality -- especially in skin tones, and dark and light scenes. This, along with a new gamma system reduces noise in monotone and shadow areas especially, for high definition images that are crystal clear. Complete Customization. Image, display and the functionality of the camera can be customized to suit your preference or application. This customization ensures that your XH A1 fits your creative, production and personal needs and preferences exactly.
Auto and Full Auto modes let you concentrate on your subject and the composition of your shot rather than exposure, or make it easy maintain exposure during shots with lighting conditions that change. Manual lets you control every aspect of your exposure manually. With Tv priority, you select the shutter to match your subject; for example, you might select a shorter shutter speed for a fast moving subject. With Av priority, you select your aperture; for example, you might want more control over your depth of field.
Spotlight gives you the optimal exposure for a brightly light subject against a darker background. Night mode automatically adjusts exposure parameters to give you the best image possible of video recorded at night. Three custom functions C. Fn1, C. Fn2 and C. Fn3 are provided. Each custom function allows a total of 21 main items to be selected. All three custom functions can be recorded on a memory card, and can then be downloaded to another camcorder. Once set, the functions can be recorded on a memory card, and can then be downloaded to another XH G1 or XH A1 camcorder.
With the XH A1's versatile open-architecture approach, you can even customize your HD camcorder to record in both 60i and 50i. This optional upgrade must be performed by a Canon Service Center. Additional Features. The VF stows in the camcorder body when not in use, and can also point forward for self-portrait work. You get single image shooting, continuous shooting, high-speed continuous shooting, histogram display, AEB, image quality selection, print order, protect, slide show, and index display.

If the auto exposure lag time is not to your liking, you can go into the Custom Setup menu and dictate whether you would like changes to occur slowly, quickly, or somewhere in between. Focus was our biggest issue with XH A1, which we found to be lacking. A small sensor chip just to the right of the lens does the calculations for the gross focus adjustments, leaving the standard, internal system free to do the clean-up fine focusing.
Working together, the system is meant to not only speed up overall focus time, but to create a "snap" in the focus rather than a gradual transition. You can turn this system off and only use the internal auto focus system, if you like. In bright light, the system works just as intended, but in low light the focus still had problems. The Instant AF system did not seem to lend any improvement.
Fortunately, the manual focus controls are quite good, even if you only have the LCD or viewfinder to rely on see the Focus section below. The camcorder makes it easy to delegate controls to the auto systems. The mode dial has an Auto mode an "A" with a square around it and a full Easy mode. The latter will rarely be used, as it renders virtually all of the buttons and dials dead — a true idiot-proof mode.
The Auto mode, on the other hand, only takes aperture and shutter speed off your hands entirely. The gain, white balance, auto levels, focus, and custom keys are all accessible if you flip the correct switch see the Manual Controls sections below. In fact, even the aperture and shutter speed are available in Auto Mode if you hit the Exposure Lock button. Mainly, the Manual mode is more convenient to make changes in.
Auto mode is good only if you want to make one or two manual adjustments and have the rest run in Auto. Like nearly all Canon camcorders, there are also a couple Program AE modes, presets that give rough approximations for the best manual settings under certain shooting conditions. While there may be numerous Program AE modes in their consumer camcorders one for fireworks, one for snow, etc. In addition, somehow Canon found the time to actually improve the degree of control mainly described in the Other Manual Control section below since the XL H1.
The core controls, those most commonly used — zoom, focus, exposure, aperture, shutter speed, and gain — are mostly the same. However, because the body is considerably smaller than the XL H1, much of the functionality we loved has been forced into the menu. In order to determine the actual gain values of those choices, you have to go into the menu and set them. Small sacrifices like this have also been made to frame rate and aspect ratio settings, image stabilization, AE shift, and some audio controls.
It is still a physical lens, though, and not a digital adjustment. With room freed up on the lens barrel, they were able to add the aperture ring. The camcorder also features the new Instant AF technology, which will receive more detail in the Focus section below.
The mode dial is very similar to the XL H1. Assigning the keys is done in the System Setup menu. As mentioned above, a lot the controls that could be found externally on the XL H1 have been moved into the menu on the XH A1. The menu is accessed by the Menu button, located at the far rear of the left side. Navigating the menu is done primarily through a jog dial located on the left rear. In short, this control is too small. We have no problem with small but effective jog dials on consumer camcorders like Canon Opturas, but for a product with professional applications, the control should be larger and more thumb-friendly.
Toggling the extensive lists on each page are no great joy, either, given the fact that when you reach the bottom of a list, pushing down will not jump you back up to the top of the list. Instead, you have to push up, up, up… to get back to the top. Simple functionality like this has been a complaint of ours for years, and it certainly should have been addressed by this point. The menu is much more extensive than the XL H1, though that camcorder offered a friendlier scroll wheel to navigate.
The animated gif here of the menu illustrates all the features contained within each. In summary, the Signal Setup is for frame rates and related choices, the Camera Setup contains a lot the manual controls and auto control responses, and the Customize submenu contains the fleet of fine image quality controls listed in the Other Manual Controls section. A few seconds after the adjustment, the scale disappears. The scale icon gives you only a rough approximation of where in the zoom scale you are.
There is no numerical indication. There are three zoom controls on the XH A1. The first, a zoom ring on the lens barrel, offers the finest control. Because the zoom ring is servo-operated and not mechanical, you cannot mark fixed zoom positions with a white marker on the body. However, the camcorder does offer a Position Preset feature, that allows you to create a single fixed point in the zoom range 20x , then jump to that point at any time with a one-touch switch.
Your pre-set position appears as a yellow square on the zoom scale icon. The second zoom control is a large rocker on the right side of the top, made to fit your index and index and middle fingers while shooting. The rocker is a little more than half the size of the same control on the XL H1.
Manipulating zoom is no problem, but we found difficulties with the placement of this control in relation to overall handling.
The camcorder has a tendency to lean left, away from the shooting hand. The third zoom control is a mini rocker located on the top of the handle, just behind the accessory shoe. Positioned solely for low-to-the-ground shooting when you really need the handle, Canon gives you the option to turn the control off to avoid accidental bumping.
Adjusting the speed in constant speed mode is done by the dial labeled "Fast" on top just behind the main zoom rocker. This lens, in combination with the exceptional resolution of the imaging system produces telephoto shots that hold up extremely well in comparison to 20x optical zoom lenses on lower-priced camcorders. The XH A1 does not offer a digital zoom option like the 1.
In order to curb errors, the XH A1 is equipped with a some useful tools. The focus ring is the largest of the rings on the lens barrel, located closest to the front, measuring nearly an inch in diameter with an extra wide groove track for solid grip. In Manual Focus mode, an onscreen display appears in the lower left that indicates where in the focal range you are, displayed in meters. This can be changed to feet in the Custom Function menu. The XH A1 offers Peaking, which boosts contrast to sharpen object outlines, and Magnifying, which zooms in 2x, in order to help with manual focus adjustments.
Both of these are one-touch controls that appear only on the LCD and not the final output stream. Like zoom, you do have the ability to create a single pre-set position that can be returned to with the simple side of a switch. Pushing this will enable auto focus only as long as you keep the button depressed. In our shooting, we found this control to have a lot of trouble when multiples planes of focus were involved, particularly in 24F mode.
All these controls are, of course, great. But if the ultimate arbiter of focal quality is the shooter, the 2. The viewfinder is better, as the resolution is higher. A larger LCD, like the 3. A field monitor or studio monitor is an option for those with the budget. Only in Manual and Aperture Priority modes can iris adjustments be made.
In other modes, the ring does nothing. These values are the same in Aperture Priority and Manual modes, which marks a difference from the XL H1, which had a much wider set in Manual mode than in its Aperture Priority mode.
However, the iris ring on the lens barrel is a new feature not found on the XH A1, and the added convenience more than makes up for the abbreviated list of aperture settings. AE Shift ranges from The Exposure Lock feature, engaged by the Exp.
Lock button located at the bottom of the left side, creates an exposure scale icon onscreen. An arrow in the middle indicates where the auto controls think the exposure should rest. It can be adjusted in Manual mode or Shutter Priority mode.
This shutter range has been reduced considerably from the XL H1, though it should manage to prove satisfactory for most users. Access to the controls is simple, which is great for quick adjustments in low light and bright light shooting. Our main complaint is that the five exterior controls that work together to give you access are too numerous and too spread out to function at peak efficiency.
