Sony launched the HDR-CX7 Memory Stick AVCHD camcorder at the end of April. This is one of the elegant models that we have seen presently. This camcorder records high definition AVCHD video recording to flash media. This also underscores the advantages of solid state media, keeping on the space occupied by drive and transfer means in HDD-, DVD-, and MiniDV-based camcorders. Rather than overloading USD1200 CX7 of anything unnecessary, this camcorder embodies low profile, the silent march, speedily deployable speed. Before experiencing this hot product, there are a few facts you should know.

Features

Though we were unable to examine the quality of still images taken by the HDR-CX7 (USD 1200), we be expecting them to be very good. Still Photographs, like movie, are recorded in the Memory Stick PRO Duo card in resolutions high up to 6.1Mega pixels (2848 X 2136 Ratio 4:3) still image feature. Moreover, the camcorder can take 4.6Mega pixels (2848 x 1602, in the proportional ratio of 16:9) images during active movie recording, with options for 3.1Mega pixels (2048 x 1536, in the proportional ratio of 4:3), and VGA (640 x 480; in the proportional ratio of 4: 3) also available

The same manual and automatic menu features available in video recording can be used for shooting still images, and the built-in flash features an illumination option in low light.

Video Performance

The Sony HDR-CX7 (USD1200) is equipped with Sony high-end ClearVID CMOS sensor featuring great 1/2.9 inche gross pixels 3200000 pixels, and an effective pixels of 2280000.Though we will not get this camera in the laboratory for a some months, we can guess how it will happen from what we know of the company other AVCHD camcorders and the HDR-HC7. (USD 1130).We examined the HC7 already before this year, and that HDV camcorder is facilitated with the same 1/2.9 inch CMOS sensor. In a word, we guess the CX7 to show video performance just as of the HC7, but displaying the peculiarity of AVCHD compression.

The HDR-HC7 enhanced the company’s CMOS expertise further, with a best and higher resolution and color’s features. Sony still provides a colorful, eye-catching image outfitted to the likings of users who want their shoots to look bright, & in general ways, the CX7 should provide the same over saturation. We expect a very bright & rich photography, and HC7 turned in a resolution score almost same to this year's other HDV camera, Canon HV20.(USD 903).Because of the assertiveness of AVCHD compression, the CX7 might display a slight fall in the video resolution features, but that difference is minor.

One of the major and obvious negative features of AVCHD video is how it results in video recording. Last year, the Sony HDR-SR1 (USD1120) and Panasonic’s HDC - SD1 (USD1120) both displayed image moving that is much more important than in other compression kinds. This effect is subtle.AVCHD is also a bit noisier as compared to HDV, and the noise is harsher in low light conditions. In spite of these warning about AVCHD, it is still an impressive advancement, and the HDR-CX7 can give video results that are almost same as of its HDV sibling.

Low Light Performance

The year before 1 / 3 inches ClearVID CMOS Sony, including the HDR-HC3 (USD970) worked good in low light, however the HDR-HC7 (1/2.9 inches) showed a fall in low light video quality. This is because of the increase in pixels greater than last year's 1 / 3 inches CMOS sensors, from roundly 2100000 pixels to 3200000 pixels. That shows there are more than one million pixels more closely packed in the same space. Generally, a small size pixel collects less light as compared to a bigger one. In this context, we guess to experience the same low light result drop in the SR7 (USD1400) as compared to the previous year’s SR1, which used the low-resolution sensor on the HC3.

The most obvious drawback we noted in the HC7’s low light video recording was noise. Aiming to balance for the lesser light-gathering capability of the latest, higher-resolution sensor, Sony seems to have pumped win. It’s unclear at this stage accurately how AVCHD compression will treat with higher gain levels on the SR7, but the intrinsically higher noise levels of AVCHD may exacerbate the problem. Without manual control over shutter speed rate, balancing for low-light should be left to one of these two modes of AE: Color Slow Shutter, which slows down the shutter speed to 1 / 30 in low light conditions, or the Super Night Shot mode, which automatically slows down the rate of the shutter speed as low as 1 / 4.
