Review
I recently had the Canon GL1 and thought it was time to upgrade to Hi-Def. After reading about 30 customer and 20 pro reviews it was the only camera that was offered pro features and great image quality worth way more then the price. It is all because of the CMOS sensor the camera uses. It consumes less power, less money to produce, better image quality then CCD and does not smear light. Some people say it’s a consumer camera because it only has a one chip sensor instead of three like a CCD sensor but a CMOS sensor is a lot different then a CCD. A single chip CMOS sensor is three mega-pixels just like three CCD chips. It should be considered a pro camera instead of a consumer camera.
OK; now what the camera can do….. It has a touch screen which is handy but you have to keep wiping it off because it smudges easily. The personalized menu is a great idea; you can have all your most used items at a touch away. The cineframe and cinematone features are a good idea if you want your movies to have a more professional Hollywood look to them. The picture quality in good light is almost identical the image quality of the Sony Z1U which cost ,000 and that’s really amazing!! The low light performance is not that good, this is a downside of the CMOS sensor. I really like the exposure lever, one strange thing is that the camera does not give exposure increments like F1.6 ….. F2.6 it just gives you a bar. Three quarters of the bar is for exposure and the last quarter of the bar is gain which digitally brightens the picture and makes the picture real grainy. Just make sure you adjust the exposure manually in dark places and turn the gain off by not going to the last quarter of the bar. It has some other great features and that I am not going to go in to but you can read about them on this page. One other thing is that this camera is quite compact and I am really amazed at the picture quality that it takes.
Over all it is great camera and a good choice for any one who needs a good Hi-Def camera for a low price.
I hope this review helps and I will be adding more to this review.

I don’t know what the problem was with the guy below me. I think he had problems in low light with the camera, this camera is not the best in low light. The auto focus is a little slow indoors but it’s a lot better in good light. He also had problems with the mic, there are a lot of settings for the mic and you have to set them right to get good sound. When rewinding tapes I did not think it made a horrendous noise but it does make different pitches as you rewind it. The camera is small, they made it compact so pros could get great images in tight places. If you need a good low light camera go with the Sony V1U.

Price went up 0 from when I bought it, I guess I made a good investment.

Overview
The Sony HVR-A1U camcorder captures 1080i HDV images using a newly developed 1/3-inch type, 2.97-megapixel (total) CMOS sensor with new Enhanced Imaging Processor(tm) technology that optimizes the performance of the CMOS sensor. The result is HD quality imaging that has been used to produce television and professional film content. Available at an extremely affordable price, the HVR-A1U will be another powerful option for HD field acquisition by all video professionals.
Specifications
The HVR-A1U is a compact and lightweight handy-type camcorder, ideal for shooting environments that require mobility. Its size, combined with its long battery life (up to 80 minutes of high-definition recording with the included battery), make it easy to get the shots you need, when you need them.

HDV 1080i The HDV 1080i specification features 1080 effective interlaced scanning lines and 1,440 horizontal pixels. Interlaced pictures, which have been common to TV broadcasts from the beginning, alternately display odd and even numbered lines between each screen refresh. The HVR-A1U can also record at the HDV 720p specification, which features 720 effective progressive scanning lines and 1,280 horizontal pixels. Progressive scanning fills both odd and even numbered lines with each refresh, providing a flicker-free picture.
Not yet ready for HD? The HVR-A1U can convert material from 1080i down to 480i and output this digital video signal through its i.LINK interface or as analog signals through component, composite, or S-video connectors. When down-converting these signals, the aspect ratio displayed can be converted from 16:9 to 4:3, and display modes can be selected from squeeze, letterbox or edge crop.
1/3-inch Type, 2.97-megapixel CMOS sensor
The HVR-A1U incorporates one 1/3-inch type primary color CMOS (Complementary Metal Oxide Semiconductor) 2.97-megapixel sensor with a formatted for a 4:3 aspect ratio. The advantage of a CMOS sensor over CCD is it’s ability to process a large volume of picture data at a very small size, which makes it possible for a camera this size to capture HD video. The trade off for this kind of chip over CCD, however, is a small loss in picture uniformity and dynamic range.

| Keep an eye on audio levels on the LCD monitor |
Audio
The HVR-A1U adopts the MPEG-2 compression format, which uses 8-bit digital component recording with a sampling rate of 4:2:0. The camera uses MPEG-1 Audio Layer II audio compression format, allowing for two-channel recording with a sampling frequency of 48 kHz/16-bit. It features a built-in stereo microphone, as well as two XLR audio input connectors for use with professional-grade microphones or external audio sources. Each input level for CH1 and CH2 can be independently adjusted using two audio level dials on the camera body and viewed with an audio level meter on the LCD monitor.
Carl Zeiss Vario-Sonnar T* 10x optical zoom lens
The HVR-A1U is equipped with a Carl Zeiss Vario-Sonnar T* high definition lens with a 10x zoom function. It has the same optical coating as is used on all of the Carl Zeiss prime lenses, which produces sharp, high-contrast images with virtually no chromatic aberration.
In order to facilitate zoom control and recording operation during low-angle shooting, an additional zoom lever has been added to the camera body. There’s also a zoom/focus ring located on the lens body that allows for fine adjustments in zoom position. Furthermore, the supplied wireless Remote Commander unit can be used for external control.
Large, 16:9 widescreen color viewfinder and LCD monitor
View your subject through the built-in viewfinder, the swing-out LCD display, or both. The HVR-A1U features a 0.44-inch type color LCD viewfinder and a 2.7-inch color LCD monitor, both in a 16:9 aspect ratio. You’ll save battery time by using just one, but you may want to use one for adjusting focus and the other for monitoring audio levels. When eschewing auto focus for the fine-tuning manual focus, you can double the magnification at the center of the screen, making it easier to confirm focus settings during manual focusing. Also, the camera’s “peaking” function can provide sharp outlines on the monitor to help with manual focus.
Electronic Super SteadyShot system
Sony’s electronic Super SteadyShot System helps remove the slight hand jitter and vibration that is often the bane of video production–especially during telephoto shots. It does this by trimming off edges of the frame on the fly to counteract movement.

Tele Macro
It may seem like a contradiction in terms, but the Tele Macro function allows you to capture a macro image from a distance, which is useful for shooting small moving objects. Additionally, this function puts your subject in proper focus while leaving the background out of focus.
The Hollywood look
The HVR-A1U has features that can make your videos look more like they were shot on film. Cinematone Gamma allows operators to quickly setup and load a gamma curve with similar contrast characteristics to a film gamma curve. The Cineframe feature allows movement to be reproduced at 24 frames per second–the speed of film–as opposed to video’s 30 frames per second standard.
No new tape stock
The HVR-A1U is compatible with conventional DV tape stock, but Sony recommends the use of DigitalMaster PHDVM-63DM tape, with its dual layer of magnetic material, which delivers higher RF output, lower noise, 95% fewer errors and 60% fewer dropouts compared to regular DV tape.
