New cameras normally have a memory card preinstalled in it. However, the cards installed usually have limited capacity. So it is very likely that you would have to purchase new memory cards for storing your digital files.
How to Buy Memory Card?
When buying a memory card though, there are things to be considered.
What Card Format?
There are few card formats available for digital cameras. Among the most used is the SD card but you can find as well XQD and CFast cards.
Older cameras have less common formats like Compact Flash or CF. What’s important is to know which format type is best suited for your camera.
Cameras with high frame rates, pixel counts or large sensors or one that provides video capture normally needs a memory card that has the capability of handling bigger amounts of video/photo data at high and fast speeds at the same time.
