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.

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.

Know More About Nikon Cameras

Know More About Nikon Cameras


The Nikon brand is famous across the world. Synonymous with quality and durability, Nikon has carved out a large market for themselves, competing with the likes of Canon for the top-spot in the camera world. The Nikon company started out small but has grown into one of the most successful commercial camera manufacturers in the world. The company started from humble beginnings shortly after the end of World War II, launching the Nikon I in 1948. With this as their starting point Nikon continued to build on their success, quickly introducing a second camera to the market, the Nikon M, one year later in 1949. During the 1950s the brand continued to grow with the NP 1957 being released as a rival to beat the industry leading Leica 35mm from Germany. The Nikon camera quickly came to be thought of as one of the top choices amongst camera technology at the time.

Since these early years Nikon has grown into a powerhouse of the camera world. Numerous technological improvements have kept Nikon cameras at the top end of the camera market. The launch of the Nikon F SLR in 1959 was a landmark in the company's history setting an industry standard for SLR design. As a result it quickly became the tool of choice for a variety of professional photographers, taking precedence over the German Leica cameras that reigned before it.

By 1980 Nikon had proven themselves to be one of the best but continued to make improvements including the release of the F3 which was designed especially for astronauts on NASA space missions to use. The design was robust and easily usable by astronauts whilst they wore their restrictive space suits. It also functioned in zero gravity environments and was resistant to solar rays which posed a problem to camera technology in space previously. As a result of the success of this camera Nikon continued to design more cameras for NASA.

The success of Nikon up to this time is evident, but it has continued through the 1990s to the present day. During the '90s Nikon produced more top quality SLRs that served to retain Nikon's place at the top of commercial camera equipment standings. In 1992 Nikon released the NIKONOS RS, the world's first autofocus SLR camera usable under water. This was a big step for underwater camera use, enabling photos to be taken more easily than ever in sub-aqua conditions. Nikon went on to team up with Fuji Films producing the E2 and E2S digital still cameras in 1995. In 1997 Nikon then introduced their first digital camera called the CoolPix 100. As of then Nikon has kept itself at the top of the digital camera world with a constant stream of new releases improving digital camera technology year on year. The CoolPix S50C and P4 are both excellent compacts, particularly the P4 which is a high quality 8MP product with a large view-screen on the back. The S50C is a 7.2 MP camera boasting a huge 3 inch view-screen making taking great photos easier than ever.
