Digital camera purchase precautions

1. CCD

The pixel of the CCD is an important indicator to measure the imaging quality of the digital camera. The size of the pixel directly determines the clarity, color, and smoothness of the captured image. The pixels of the CCD basically determine the grade of the digital camera. The mid-range is generally around 800,000 to 1 million pixels, while the mid-range and high-end are generally above 1.2 million pixels. The area of the CCD is also an important indicator. The image quality of a CCD with a small area is relatively blurred, the color reproduction is poor, and the area used for anti-shake is also much smaller, so of course, the anti-shake function is relatively weak. Brands such as Sony and Samsung on the market have launched products with more than 1.2 million pixels. Especially noteworthy is Samsung's D93i, D99i series DV, 1/4-inch 1.33 million pixel CCD makes the image clearer and the color more full.

2. Lens

Like a digital camera, the lens is also an important factor in determining the image quality of a digital camera. The lens first depends on the optical zoom factor, which refers to the optical zoom. The larger the optical zoom factor, the greater the degree of choice in the size of the scene we shoot, which will bring great convenience to our composition when shooting. This point It is the same as the zoom lens of the camera; the second is the aperture of the lens. If the aperture is small, even if the pixel is large, it will not be able to shoot well in the case of dark light, that is to say, it will become a digital camera. A bottleneck in imaging. Samsung's new D10xi and D30xi series have a maximum optical zoom factor of 20 times and a lens diameter of 30mm (5mm wider than some models on the market).

3. Shape and volume

Buying cameras are generally entertainment in nature, so it is necessary to consider the shape. Another is the size. Home cameras are generally carried when going out, so it is very necessary to be small and exquisite. The most important thing is that you can shoot in any posture without having to limit the shooting angle of view because of the person's position. The 10 new products recently launched by Samsung are 15%-20% smaller than the previous products, and the body is more compact and small, which is convenient to carry when going out.

4. Simple and convenient operation

For ordinary consumers, the simplicity of operation is a necessary condition for machine selection. Samsung's various series of DV unique simple Q function and simple navigation knob, so that ordinary consumers can quickly operate proficiently. Simple Q function can ensure that users can take the same wonderful picture under any conditions. When using the Easy Q function, the user just presses the Easy Q button and everything is done. The simple navigation button feature allows you to quickly and easily find the most frequently used functions. Turn the knob up and down to perform 8 functions including manual/auto focus, shutter speed/exposure, white balance, digital stabilizer, etc. The new Samsung digital camera series also specially designed bilingual menus in Chinese and English, which makes the operation more convenient.

5. Compatibility

The wonderful pictures in life often have to be shared with good friends, but if the memory cards of different cameras are not compatible, it will be a disappointment. That is to say, there are four kinds of cards, MS, MSPro, SD, and MMC in the market. The high compatibility makes it possible to transmit images and sounds between different cameras. The DV machine is compatible with four cards, which is unique to some new Samsung products.

6. LCD screen

Professionals often shoot, and the composition is relatively familiar, so they can not use the display screen, but most of the ordinary users use the LCD screen when shooting. In fact, the LCD screen does not have any profound name, the main thing is that the brightness should be high enough, the pixels should be large enough, and the larger the area, the better, the more popular ones are 2.5 inches and 3.5 inches. If the light-transmitting and reflective LCD screen is used, the view can be clearly viewed even in the face of the sun, and there is no need to be afraid of the black screen.
