Teach you how to buy a digital camera memory card

Nowadays, digital cameras have entered people's lives, and people are increasingly feeling the Convenience of a digital camera. We know that digital cameras compared to traditional cameras biggest difference is - digital camera with a rewritable digital camera memory cards instead of the traditional disposable film camera to record the image. Thus, to some extent, the memory card can be understood as a digital camera's "film." As a digital camera memory card "film", although it relationship with the camera's image quality is minimal, but the "digital film" is related to the time you are using a digital camera can take pictures of storage volume and speed of each photo. Because of this, digital camera memory card to become the most important digital camera accessory igogo
Now we buy a digital camera usually comes standard with a memory card, but the standard memory best action camera card capacity can not meet the current needs of consumers shooting (generally not more than 32MB). 16-32M capacity memory card for the mainstream now 300-400 million pixel digital camera, at maximum resolution it can store hundreds of photos, but for those 5 million -800 million-pixel digital camera, and even Digital SLR cameras simply can not be used, therefore, for the current mainstream digital cameras, we recommend at least 128M memory card, and for more than 5 million pixel high-end digital camera, preferably with a 256M or larger memory card.
In order to better to buy a digital camera memory card, we first understand the next current digital camera memory card types on the market.
Digital camera memory card introduced species:
1. SM Card (Smart Media)
SM (Smart Media) card by Toshiba Corporation in November 1995 release of Flash Memory storage card, Samsung in 1996 purchased the production and sale of licenses, the two companies become a major SM card vendor. In order to promote SmartMedia become the industry standard, in April 1996 established the SSFDC Forum (SSFDC ie Solid State Floppy Disk Card, SmartMedia when in fact the beginning is called SSFDC, was renamed SmartMedia, and became a registered trademark of Toshiba) . SSFDC forum has over 150 members, also includes many large manufacturers, such as Sony, Sharp, JVC, Philips, NEC, SanDisk and other manufacturers. SmartMedia cards are also common market, micro memory card, once in the MP3 player is very popular. SM card size of 37mm × 45mm × 0.76mm, the SM card itself does not control circuit, and made of plastic (to be divided into many thin slices), so the small size SM card is very thin, in 2002, had previously been widely used in Among digital products, such as the old models of Olympus digital cameras and Fuji digital cameras use more old SM memory cards. However, SM card control circuit which is integrated in the digital products (such as digital cameras), which makes the digital camera compatibility vulnerable. It is also because of this problem, the current new digital cameras have not adopted SM memory card product.
2.CF card (Compact Flash)
CF card by the U.S. SanDisk, Hitachi, Toshiba, Germany Ingentix, Panasonic and other 5C Alliance pioneered in action video camera already has the Canon, LG, Epson, Casio, Minolta, Nikon, Kodak, NEC, Polaroid, Panasonic, Psion, HP and many other OEM customers and partners, vendors very solid foundation. CF card and SM card, are the earliest storage card products, CF card currently on the market is divided into two kinds of CF Ⅰ and CF Ⅱ. Close to its shape and use the same 50-pin interface, but because of CF Ⅱ increased thickness of 5mm, so in terms of volume than CF Ⅰ big. Also worth noting is that only supports CF Ⅰ card digital camera is not supported by CF Ⅱ cards, however, because of its own with a memory interface and controller, so CF Ⅱ card camera can be backward compatible with CF Ⅰ. Canon and Nikon digital cameras are staunch supporter of the CF memory card, and almost all digital SLR cameras use CF card as storage medium. Although the CF has been around for a long time, but still exudes vitality, many large capacity, small volume of CF types of memory cards has introduced, including the IMB and Toshiba mini hard drive series, in addition to other manufacturers like Sandisk also developed a capacity of up to 6G CF card, these large capacity CF card in the professional digital cameras have sufficient space to play igogo
Now digital camera with a CF memory card, access speed flag is ×, where "1 ×" = 150KB / s, for example: 4 × (600KB / s), 8 × (1.2MB / s) 10 × (1.5 MB / s), 12 × (1.8MB / s), now has the highest 40 × CF memory card. Relatively speaking, a faster CF card will increase the digital camera shooting, but the practical application of which some middle and low-end digital cameras due CCD sensor, the use of components, as well as technical reasons, even when using a higher speed CF memory card, the speed advantage can hardly reflected. So I recommend high-end digital camera users may consider choosing a high-speed CF memory card to speed up access speed, to ensure the effect of shooting.
