High definition camcorders before making any purchase is a smart idea. Just like anything else you want to make sure you are getting exactly what you want, especially when you will be spending a decent amount of money. When you are comparing camcorders you should know that they may be referred to in many different ways.

When buying an HD camcorder, there are many details to look for. One of the most important ones is the media type it records the video to. There are 4 well know media types/storage for digital camcorders and HD camcorders:

The traditional tape, miniDV for standard resolution and High Definition miniDV
Hard drive storage.
Flash memory
DVD (3.15″)

MiniDV Tape

Traditional media for those who like to archive tapes: This type of media offers great video quality but video transfer to a computer can be quite slow. This is a media type that will soon or later disappear.

Widely availability
Easy use and storage

This type of media is the most widely used, it's recommended for anyone.

Hard Drive Storage

Hard drive based camcorders can record many hours of video without having to worry about changing the tape/card or dvd. It's completely reusable, once full, you will simply purge the stored video and it ready to continue recording. On the downside, hard drive based camcorders are more sensitive to shock, since they have parts moving at high speeds.This types of cameras tend to be heavier than others.

Lot's of video storage
No need to keep changing media
Reusable

This type of media is more recommended for computer savvy users.

Flash Memory

With the drops in memory prices and their increasing storage size, without doubts, this is the media type of the future, which you can enjoy now. Currently, one can buy a 32GB SDHC memory card for less than $100, that's a lot of pace in a very compact card. Memory card based camcorders can be more compact and consume less power than the other types.

Cost effective
Can be reused unlimited times
Can be used in more compact designs
Great for pictures

This type of media is more recommended for computer savvy users or for those willing to learn something new.

DVD based camcorders

DVD media is a great option for those who don't want to waste time transferring or editing video. They tend to be costly and harder to find. Keep in mind that these 3″ discs only offer 1.4GB of storage or around 30 minutes of video.

Easy to use
Fast recording/viewing
Compatible with RW discs (rewritable)

This type of media is recommendable for any type of user.source:hdcamcorder-s.com/tag/camcorder-camera


HD camcorder, and hi def camcorder are some of the names used for this camera. A few things you may want to compare are the technology, the price, the size, the quality, and the resolution at which it records.

Comparing the Sony High Definition Camcorder With JVC's Offerings

In September 2008 Sony announced the unveiling of its high definition camcorder, which greatly accelerated the growth of this particular segment of the electronic home entertainment market.

This new high definition camcorder was called the HDR-FX1 which used 1080 lines horizontal resolution with a frame rate of 60 interlaced frames per second and recorded to standard MiniDV tapes. The high definition camcorder specifications were in agreement with other manufacturers such as JVC, Canon and Sharp. In addition, the high definition camcorder has supporting software for video editing from such heavyweights like Apple and Adobe.

The Sony HDR-FX1 camcorder was the first in terms of technology but the HDR specifications are derived from compression standards first introduced by JVC camcorder HDV specs. JVC's first camcorder known as the GR-HD1 which the consumer could use before Sony camcorders had entered the market, also had a companion camcorder known as JY-HYD10U which was based on the technology used in all of JVC's professional line of camcorders.

The difference between the JVC and Sony high definition camcorders is in the way that shooting is done. With JVC camcorders, shooting was done with 720 lines of resolution at a rate of 30 progressive frames every second, whereas the Sony camcorder shot at 1080 lines of resolution at 60 interlaced frames every second. However, both rates contain the same amount of information, where JVC offers progressive scanning and Sony offers a higher resolution picture.

The two brands have the same method of compressing information into a MPEG2 signal, which can then be saved on standard MiniDV tapes. In addition, both brands also can record standard DV signals as well as HDV signals. With the HDR-FX1 comes three 1/3 inch 16:9 1.12 Megapixel gross CCDs, with each CCD measuring 960 x 1080 pixels and the pixels themselves are oblong and not square thus allowing the camcorder to shoot 16:9 aspect ratio video.

The expected street price of the Sony HDR-FX1 should be approximately $3,500, which is about a thousand dollars less than when the first MiniDV camcorders were introduced and at this price, Sony can begin competing with professional models offered by other brands. Added to the competitively priced Sony high definition camcorder is the fact that its new real time HD codec engine can code and decode the HDV signals.

Sony Global - Digital SLR Cameras

Sony Global - Digital SLR Cameras

There is quite a bit of news to share from the Sony α (alpha) team today as three new cameras and three new lenses have just been unveiled. For you photographers who never want to miss a moment like a subtle smile or a sports action shot, our latest innovations will help you capture these perfect moments.

The first two, the α55 and α33, use a Phase Detection auto focus system for the highest level of focus speed and accuracy for both still and video images. The α55 can shoot and focus continuously at up to 10 frames per second, while the α33 can shoot seven frames per second, achieving shooting speeds that are the fastest in the industry for sub $1000 interchangeable lens cameras (as of Aug 2010).

These cameras use a fixed Translucent Mirror Technology, which allows them to continuously and quickly focus, helping you capture important moments with sharp images. The Translucent Mirror Technology also works while recording video in full HD. It’s the kind of performance that has been impossible to get in any traditional video capture technology.

The α55 has a large 16.2 megapixel Exmor™ APS HD CMOS sensor and the α33 has 14.2.

“This is the most innovative Interchangeable Lens Digital Camera that Sony has ever created,” said Kristen Elder, director of the digital imaging business group. “Our Translucent Mirror Technology is one of the most significant SLR structural changes in more than a decade.”
The new Translucent Mirror Technology allows light passing through the lens to be directed to the image sensor and the auto focus sensor at the same time. The new structure eliminates a moving mirror mechanism, making the body size smaller and focus time faster since the mirror does not need to be raised and lowered allowing it to focus while it’s shooting instead of in between shots like traditional SLRs.

These cameras boast both constant live view through the 3-inch diagonal Xtra Fine articulated LCD™ with 921,600 dots with TruBlack™ technology and the Tru Finder™ electronic eye-level viewfinder. This means what you see is what you get with 100% framing accuracy and real time view of the creative adjustments you make.

Also announced was the α560 which is a traditional DSLR using an optical viewfinder that now captures full HD video and stills at up to seven frames per second using the 14.2 APS HD CMOS sensor.

All three cameras are compatible with all A-mount lenses so video and photography enthusiasts can choose from macro to telephoto lenses.
A newly developed Autofocus sensor assures ultra-fast, high precision focusing. All three cameras use this new 15-point Phase Detect sensor, which significantly increases the auto focus system to lock on to subjects which may not be centered in the frame.

The 55 and 33 use Phase Detection for high speed shooting and HD video capture which tracks rapidly moving subjects accurately. These cameras are the first in the world to have this feature work while recording in Full HD AVCHD™ movie shooting mode. This is the kind of feature that will be very useful for capturing fast action and for catching subjects that move quickly towards or away from the camera.

Other key features to note:
· Exmor™ APS HD CMOS sensor, BIONZ® high-speed image processing engine and ultra-high ISO sensitivity (ISO 100-12,800) to get the best shot, even in difficult lighting situations.
· Auto HDR shoots and combines three frames into a single high dynamic range photo with rich shadow and highlight detail.
· Multi frame noise reduction. (shoots and combines six frames into a single photo) for smooth low-light imaging at half the noise level and Hand-held Twilight which shoots and combines six frames into a single photo, suppressing blur to enable clear night-scene imaging without a tripod or flash.
· 3D Sweep Panorama™ technology for panoramic photos that can be viewed in 3D on compatible 3D systems and other devices that support 3D technology.

The α55 will be available in October and cost about $750 for the body and $850 for the body and 18-55mm zoom lens. The α33 camera, which will be available in September, will be $650 and $750 for body and 18-55mm zoom lens. Watch out for them at Sony Style® retail stores and at authorized dealers nationwide. The α560 model with the camera body and 18-55mm kit lens will cost about $750 and will be available in October. With the body only, it will cost about $650.

If the new cameras are not enough for the Sony photo enthusiast, we also have 3 new lenses that add to your repertoire and grow the already expansive A mount system of lenses. New today are a Carl Zeiss® Distagon T* 24mm F2 ZA SSM (model SAL24F20Z), a DT 35mm F1.8 SAM (model SAL35F18) and an 85mm F2.8 SAM (model SAL85F28).
“These new lenses and cameras show our commitment to the DSLR market and that we will never stop innovating.” said Kristen Elder.
