I want to buy a Pentax SLR camera, but I have a problem in choosing an SD card. What's the difference between Kingston and Toshiba's SD card?

Compared with the brand, the most important thing is to look at the technical indicators of the card. For example, each brand has memory cards with different technical indicators (that is, different transmission speeds), such as ordinary cards, high-speed cards, and special high-speed cards for shooting, so you can't match the appropriate memory cards according to the body just by looking at the brand.

Generally, the lower transmission speed limit of this kind of memory card is expressed by class, which generally has five grades: class2, class4, class6, class8 and class 10, of which class2 is the slowest and class 10 is the fastest. On the sticker of the memory card, the word "C" will be displayed, and the number of this level will be wrapped inside. Pentax K-X, K-R and K-7 need at least 6 types of high-speed cards to meet the requirements of 720P high-definition cameras and continuous shooting speed of 5~6 frames. If it's Pentax K-5 with 1080P full HD, it's better to get a class 10.

When choosing a card, the most important thing is to see what grade this card is. At present, the latest Kingston SD cards are all blue stickers CLASS 10, and only 8G is bought here in Guangzhou, around 90 yuan, which is the most valuable one in the memory card. However, if you want to pursue better quality and speed, I recommend you to buy the class 10 memory card with the highest speed of SanDisk (note that it is not the Ultra series or the ordinary series with the lowest speed), and the online shopping price of 8G is around 130. Class 10 8G Toshiba baikayo 1 10 yuan is a compromise.

Of course, SanDisk, which specializes in storing photographic equipment, is the most trustworthy of the three. Naturally, it is expensive (quality and speed are more reliable). Kingston and Toshiba White Card are both class 10, and the actual transmission speed has not been compared, so it is not easy to compare, but Kingston's new card is more than Toshiba White Card, so if you are short of money, I suggest you buy Kingston's.
