Memory cards: what should I keep in mind?
What type of memory cards are there?
There are 3 sizes of memory cards: SD cards, microSD cards, and CF cards. These cards have different dimensions. Your camera will only fit 1 kind of memory card. Usually, it's an SD card. Do you have an action camera? In that case, you'll need a microSD card. It's smaller than the others and is used in compact devices.
