The number shown at the bottom of the viewfinder — 39, in Figure 1-15 — represents the number of maximum number of burst frames. This number relates to shooting in the Continuous shooting mode, where the camera fires off multiple shots in rapid succession as long as you hold down the shutter button. (Chapter 2 has details.) Although the highest number that the viewfinder can display is 99, the actual number of maximum burst frames may be higher. At any rate, you don’t really need to pay attention to the number until it starts dropping toward 0, which indicates that the camera’s memory buffer (its temporary internal data-storage tank) is filling up. If that happens, just give the camera a moment to catch up with your shutter-button finger.

The maximum burst value also makes an appearance in the Quick Control screen when the camera is set to an advanced exposure mode (P, Tv, Av, M, B, C1, or C2) after you press the Shutter button halfway down. It is displayed directly to the left of the shots-remaining value. The good news is that you rarely need to even worry about this number; we just bring it up so you don’t scratch your head wondering what that value means when you see it on either display.
