How to buy the memory card of the camera?

Generally, a camera can support 32G memory card at most, but I suggest you buy 16G memory card. 16G ordinary high-speed memory cards are around 220 yuan, while those that are more expensive than 220 yuan are all ultra-high-speed cards. Remind me not to buy ultra-low-priced memory cards online, such as Taobao and Paipai. Those are fake cards, which can't be opened and are easy to lose files. Fake cards can be verified by licensed products in official website, so many people can buy them.
