Micro SD cards are a specific type of memory card, smaller than Secure Digital (SD) and other formats generally used in digital cameras. They’re more commonly used in mobile phones and tablets, giving them a bit more storage for apps and media, as well as action cameras and other types of smaller devices.  

Though they may be small, micro SD cards offer high capacity storage and lightning-quick transfer speeds. A good micro SD card can handle hours of video or hundreds of images, so you don’t need to sacrifice your shooting just because you’re using a smaller card. Here we’ll take you through the basics of micro SD cards.
