Product Description
Sony HVR-A1U 1080i HDV camcorder provides real 1080i HD acquisition, with superb image quality and comprehensive functionality for professional use, in a "handy" camcorder form factor. This new HDV camcorder will help to expand the adoption of HDV and lead the entry level HD market by providing a compact and low cost solution. The new HVR-A1U features a newly developed 1/3 inch C-MOS imager. This new 1920x1080 native imager is also capable of 3 mega-pixel still images. Combined with a high quality Optical Zoom Carl Zeiss Vario-Sonnar T* Lens and Sony's new 14 bit A/D and DXP digital Extended Processor, result in precise image acquisition with superb detail and clarity. The new HVR-A1U records this exceptional imagery using the recently adopted HDV 1080i format onto a DVCAM mini cassette. Resolution of up to 1440x1080 with pixel shift 2.7 16 - 9 Hybrid LCD Display with touch panel function (simultaneous use of LCD and viewfinder is possible) Image Stabilization XLR Audio input connectors Built-in Wide Range Stereo Microphone Built-in Dynamic Speaker
Amazon.com Product Description
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.

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.
