Display and hide the Quick Control screen. By default, the screen appears automatically when you turn on the camera and then turns off if no camera operations are performed for 30 seconds. You can turn the display on again by pressing the shutter button halfway and then releasing it. To turn off the display before the automatic shutoff occurs, press the Info button (on the back of the camera, just below the power switch). Press the Info button twice to cycle back to the Quick Control screen. You can adjust the timing of the automatic shutdown of this screen and others via the Auto Power Off option on Setup Menu 2. We provide the details near the end of this chapter, in the section devoted to that menu.
Keep an eye on the battery symbol and the shots remaining value. A full battery like the one in the figure means that the battery is charged; as it runs out of power, bars disappear from the symbol. The shots remaining value indicates how many more pictures will fit in the free space available on your memory card. This value depends in large part on the Image Quality setting, which determines the resolution (pixel count) and file type (Raw or JPEG). If those terms are new to you, the next chapter explains them.
You can replace the Quick Control screen with an electronic level by pressing the Info button. This feature is useful when you use a tripod and want to ensure that the camera is level to the horizon. When the horizontal line appears green, as shown in Figure 1-14, you’re good to go. Press Info again to return to the Quick Control screen. You can enable or disable the level and Quick Control screen from Setup Menu 4, as described in the Setup Menu 4 section later in this chapter.

Decoding viewfinder data
A limited assortment of shooting data, such as the shutter speed and f-stop, appears at the bottom of the viewfinder, as shown in Figure 1-15. In the framing area of the viewfinder, you may see marks that indicate the portion of the screen that contains autofocusing points. (The appearance of the autofocus markings depend on your autofocus settings, which you can explore in Chapter 5.) In the first screen in the figure, the four black brackets represent the autofocusing area.
FIGURE 1-15: The default viewfinder display (left) can be customized to include a grid, electronic level, and flicker warning (right).
In the following sections, we walk you through how to display and customize the viewfinder.
Displaying viewfinder data
The markings in the framing area of the viewfinder appear automatically when you first turn on the camera; to display the shooting data, you must press the shutter button halfway. The display remains active for a few seconds after you release the button, and then the viewfinder display data shuts off to save battery power. To wake up the display, press the shutter button halfway and release it.
Adding a level and gridlines to the display
You can display gridlines in the viewfinder, as shown on the right in Figure 1-5, as well as a symbol that represents the electronic level. (When the lines at the sides of the symbol are horizontal, as in the figure, the camera is level.)
To hide or display these features, open Setup Menu 4 and choose Viewfinder Display. On the next screen, change the settings from Hide to Show. As you select each option, a preview appears at the bottom of the screen to remind you how enabling the feature affects the display.
Displaying a flicker-detection warning
When the Mode dial is set to an advanced exposure mode (P, Tv, Av, M, B, C1, or C2), the Viewfinder Display option offers a third setting, Flicker Detection. When the camera detects light sources that are blinking, which can mess up exposure and color, the word Flicker! appears in the area labeled in Figure 1-17. The biggest offenders are tubular fluorescent bulbs, which blink on and off so quickly that it’s difficult for the human eye to detect them. When you see this warning, you may want to enable the Anti-flicker Shoot option on Shooting Menu 5. This feature, covered in Chapter 4, also is available only in the advanced exposure modes.
Noting the bottom right number
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.
Reading the LCD panel
Another way to keep track of shooting information is through the LCD panel on top of the camera, shown in Figure 1-16. Don’t see any data in the panel? The camera is probably in sleep mode; give the shutter button a half-press to wake it up.
FIGURE 1-16: The top LCD panel is another useful situational awareness tool.
As with the viewfinder and Quick Control screen, the panel shows you the shots remaining value and battery status, as labeled in Figure 1-16.
