When new cameras are announced, the speed in frames per second is one of the very interesting features. We want a camera to be fast to capture animals in motion. Nothing is more frustrating on a photographic safari than pressing the shutter and nothing happens. Sometimes the missing focus is the reason, but often it is the speed. And very often it is not even the camera that slows down the process; it’s the memory card. You can have a fast camera, but it will not be able to use its entire abilities when the memory card is to slow in processing the images. Then you see the message “buffering” and the lion kill is just happening in front of you.
Be conscious about that when purchasing memory cards. Always ask what card suits best the abilities of the camera. When you are attending photography courses make it a topic to understand better what memory card to use when and for which camera. It will make you a happier photographer, shooting away at great sightings in the bush and elsewhere.
