Its results were always adequate, and the camcorder always recorded a decent image even in very low light. Battery life was simply crazy-good, with the camcorder managing to record for over five hours on a continuous charge.
That awesome performance is a rather important one for many pros who could be lugging the XH A1S around for a full day of shooting. We like the Canon XH A1S, but its tape-based recording system is a bit outdated in our increasingly non-linear world. Many pro camcorders are beginning to include the ability to record video to memory cards, just like the bulk of the consumer camcorder market, thus making it much easier to get footage onto a computer for editing.
Of course, the tape-based media on the XH A1S does have its charm, and it definitely helps keep the costs of production down, too. If you like what the XH A1S has to offer, but are concerned about its design, the larger XL H1A has a much smoother interface and handles better too, due to its more spacious body. Of course, it's also a lot more expensive, thanks to its interchangeable lens system. The XH A1S does a ton of things well, but it is rarely capable of kicking things up to the next level.
Results from our performance tests show a camcorder that captures colors accurately, handles its own in low light, and produces a decently-sharp image. But some of the best HD consumer camcorders we reviewed this year are actually a bit better in certain categories.
Either way, the XH A1S is still a solid performer, and its videos never looked bad; but for all that, it's not the elite camcorder that it should be either.
When testing the camcorder with absolutely no gain boost 0dB gain setting , the XH A1S required 61 lux of light to register 50 IRE on our waveform monitor. With auto gain engaged which allows the gain levels to go as high as 18dB , the camcorder needed just 7 lux of light to reach the same level.
Since the camcorders have the same sensors, it is likely that this disparity is a result of the difference in lenses. We also tested the sensitivity on the XH A1S using its alternate frame rate settings.
Recording with the camcorder's 24p and 30p modes, we found the low light sensitivity drastically improved. This makes sense, as the lower frame rates use slower shutter speeds and allow more light to hit the sensor.
So, if you know you'll be filming in 24p, you can expect a much better low light performance from the XH A1S compared to its 60i results.
The camcorder measured a color error of 4. While these numbers aren't all that impressive, keep in mind that the XH A1S is a pro camcorder and it offers numerous modes and settings for adjusting color. This is not unusual—most camcorders struggle with this test. With 0dB gain, the camcorder measured a color error of 6. Despite the low saturation level, the camcorder produced some strong colors and retained quite a bit of detail. Its color error improves a lot down to 4.
In fact, the 6dB gain image looks almost as bright as the camcorder's auto gain setting image. With 0dB gain, a camcorder should produce far less noise. To its credit, the XH A1S does have a -3dB gain setting and its noise reduction options can be used to bring down the noise levels even further.
Interestingly, the noise levels went down slightly when we raised the gain from 6dB to 12dB. The noise levels didn't go up much, however, with the camcorder registering 2. As we saw in the previous tests, this noise level is higher than the other two camcorders we used as comparisons.
The XH A1S achieved its lowest noise levels when we tested it using its auto gain setting. The Professional L Series Fluorite lens of the XH A1 ensures outstanding resolution, contrast and color reproduction, and delivers clarity and image quality you won't see with conventional optical glass lenses.
And, because it's an ultra-low dispersion UD lens, chromatic aberration is reduced for brilliant results. The design lets you operate the zoom using the lens barrel ring, the control on the camera's grip, or the control on the camera's handle.
When using the zoom ring on the lens, you can control the speed of your zoom by varying the angle of the ring, or by varying the speed at which you rotate the ring. When using the grip control, you can zoom at 16 different speeds; or you can use the control to operate at a single zoom speed which you preset. When using the handle zoom control, you can operate the zoom at a single speed which you preset.
You can also select high-speed zoom to increase the zoom speed when using either the grip or handle control. And, because the lens is designed with a zoom ring, you can operate zoom, focus and aperture using a single hand. It also comes with 2 built-in ND filters, and can be enhanced with an optional WD wide converter. They deliver outstanding picture quality, highly accurate color reproduction, and a wide dynamic range with virtually no color noise. 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.
