Who knows about cameras? Which one is suitable to buy?
LCD display screen
For any digital camera, the LCD screen is responsible for framing, playback and menu operations at the same time, so it is also very critical. At present, the screens of the more mainstream digital cameras are all over 2.5 inches. The larger the screen size, the better the effect can be achieved in terms of viewing, playback and menu operations. At present, some 3.5-inch products are gradually beginning to appear in LCD screens for digital cameras. The screen has a touch function, and menu operations can be operated intuitively on the screen, which is very convenient for those who are not very proficient in digital products. After Sony took the lead in launching touch screens, Canon, Panasonic and other manufacturers have also launched such products.
16:9 is another trend in the popularity of DV screens. It is said that the 16:9 display is the optimal size designed based on the distance between human eyes, allowing people to experience the full visual experience when watching video content. for the best visual impact. In addition to DV, 16:9 widescreen mode has actually become popular in both LCD TVs and computer monitors. For example, Sony DVD camera DCR-DVD905E, Panasonic GS400, Sony's two latest high-definition cameras: HDR-UX1E and HDR-SR1E both use 3.5-inch and 16:9 touch-type wide LCD screens.
Sensors and pixels
In the past, the image sensors of digital cameras used single CCD or 3CCD. For example, Panasonic has many products that use 3CCD. But in 2005, Sony Handycam took the lead in installing CMOS sensors on the tape DV-DCR-PC1000E. Later in 2006, CMOS appeared on the Sony DVD digital camera DCR-DVD905E and the AVCHD-compliant high-definition hard disk camera HDR-SR1E. The appearance of CMOS sensors on digital cameras is a requirement for digital cameras to enter the high-definition era. Its emergence has accelerated the process of high-definition cameras and the popularization of high-definition cameras. For digital cameras, everyone has a common sense that the higher the pixels, the more helpful it is to improve the image quality. At present, mainstream products have reached more than one million pixels. Products with total pixels of 3 million and 4 million pixels are now common in the market. If the purchase budget is generous enough, then try to choose products with high pixels or CMOS sensors.
Lens and Zoom
For a digital camera, the lens is like an eye. The quality of the lens also has an impact on the imaging of digital cameras. An excellent lens is the guarantee of imaging quality. As we all know, the imaging quality of German optical lenses is world-renowned. Sony and Carl Zeiss have a history of cooperation for many years. Many Sony digital cameras use the famous Carl Zeiss Vario-Sonnar T* lens, which has laid a solid foundation for the imaging quality of Sony digital cameras. the basis of. In addition, Panasonic also cooperates with Leica.
The lenses of digital cameras all have zoom functions. The more common ones use 10x optical zoom lenses, but there are also some products that use 20x optical zoom lenses. For example, the Sony DCR-SR40E is such a camera with a large Digital video camera with zoom lens. The optical lens with a large zoom ratio can clearly magnify and reproduce scenes that were previously invisible from a distance in front of your eyes. Generally, digital cameras also have an electronic zoom function, but when the electronic zoom is turned on, the image quality will be greatly affected, so it does not have much practical significance.
Storage media
The storage media of digital cameras can be divided into four categories: tape, DVD disc, hard disk and flash memory. Hard drives and DVD discs are currently the mainstream products on the market and have become the first choice for consumers. Hard disk digital cameras store the captured images on the hard disk in MPEG-2 format. It eliminates the steps of collecting and converting formats required by previous tape digital cameras. After connecting to the computer, you can directly burn DVD discs. The capacities of hard disk digital cameras on the market range from 20G to 60G. Currently, the only product with a maximum capacity of 60G is the Sony DCR-SR80E. At the same time, Sony also has the only hard disk high-definition digital camera on the market - the Sony HDR-SR1E that adopts the AVCHD high-definition standard.
Digital cameras that use optical discs as storage media can burn a DVD simultaneously while shooting. Users who do not have too many requirements for post-editing can consider this type of product. Several major manufacturers, including Sony, Canon, Hitachi, Panasonic and Samsung, now have DVD disc digital camcorder products.
I believe that after reading the above words, you can already have a basic understanding of digital cameras. You should also know what you need to pay attention to when purchasing. Purchasing a digital camera that you like is just the first step towards a life of imaging. Being proficient in operating the equipment in your hands and constantly improving your shooting experience are also necessary tasks for a DV enthusiast.
