Burst Rate

What Does Burst Rate Mean In A Camera? When you camera is set in continuous shooting mode, it will continue to shoot photos as long as you hold down the shutter button.  The speed at which it takes the photos is known as FPS, or Frames Per Second.  Before photos get written to the memory card, they are first stored to a small amount of internal memory in the camera called a buffer.  This buffer memory has a very fast write speed, faster than a regular memory card which is why they do this.  Once stored in the buffer, the …
