At the heart of a digital camera lies the SD card. Differences in capabilities, capacity, and speed mean careful consideration is necessary. Class 2 SD cards work for standard definition video, while Class 4 and up support 1080p full HD video. Class 10 SD cards are the fastest and are meant for still photography, even burst shooting.
