Exploring External Camera Features

Оглавление

Scattered across your camera’s exterior are numerous features that you use to change picture-taking settings, review your photos, and perform various other operations. Later chapters explain how and when to use these tools; the following sections provide a basic “what’s this thing do?” introduction to them. (Don’t worry about memorizing the button names; throughout the book, figures and margin symbols tell you exactly which button or switch to use.)

Topside controls

Your virtual tour begins on the top of the camera, shown in Figure 1-6.


FIGURE 1-6: Here’s a guide to controls found on top of the camera.


The items of note here are

❯❯ On/Off/Movie mode switch: As outlined in the preceding section, setting the switch to movie-camera icon turns on the camera and sets it to movie-recording mode. Set the switch to On for still photography.

Even when the switch is in the On position, the camera automatically goes to sleep after a period of inactivity to save battery power. To wake the camera up, press the shutter button halfway and release it. See the information related to the Auto Power Off setting, found in the section Setup Menu 2” for help adjusting the timing of the automatic shutoff.

❯❯ Mode dial: Rotate this dial to select an exposure mode, which determines whether the camera operates in fully automatic, semi-automatic, or manual exposure mode when you take still pictures.

❯❯ Viewfinder adjustment dial: Use this dial to adjust the viewfinder focus to your eyesight, as outlined in the preceding section.

❯❯ Main dial: As its name implies, this dial is central to many camera functions, from scrolling through menus to changing certain shooting and playback settings.

On some camera screens, you see a symbol that resembles the top half of a dial with notches around the edge. That’s designed to remind you that you use the Main dial to adjust the setting. Similarly, on some screens, a pair of curved arrows is perched above a picture-taking setting. Those arrows also indicate that you can rotate the dial to adjust the setting.

❯❯ Red-Eye Reduction/Self-Timer Lamp: When you set your flash to Red-Eye Reduction mode, this little lamp emits a brief burst of light prior to the real flash – the idea being that your subjects’ pupils will constrict in response to the light, thus lessening the chances of red-eye. If you use the camera’s self-timer feature, the lamp lights during the countdown period before the shutter is released. See Chapter 2 for more details about Red-Eye Reduction flash mode and the self-timer function.

❯❯ AF Area Selection button: Press this button to access the AF Area Selection setting, which is related to autofocusing. Chapter 5 explains.

❯❯ ISO button: True to its name, this button displays a screen where you can adjust the ISO setting, which determines how sensitive the camera is to light. Chapter 4 details this critical setting.

❯❯ DISP button: This button affects the Quick Control screen, which displays shooting information when you’re taking still pictures. (Check out “Displaying the Quick Control screen, later in this chapter, for a look.) Normally, the screen appears automatically when you turn the camera on or press the shutter button halfway and release it and then turns off after a period of inactivity. But you take control over the display by pressing the button, which toggles the Quick Control screen on and off.

❯❯ Shutter button: You no doubt already understand the function of this button, but you may not realize that when you use autofocus and autoexposure, you need to use a two-stage process when taking a picture: Press the shutter button halfway, pause to let the camera set focus and exposure, and then press down the rest of the way to capture the image. You’d be surprised how many people mess up their pictures because they press that button with one quick jab, denying the camera the time it needs to set focus and exposure.

❯❯ Flash hot shoe: Labeled in Figure 1-6, this is the connection for attaching an external flash and other accessories such as flash adapters, bubble levels, flash brackets, off-camera flash cords, and the GP-E2 GPS Receiver.

❯❯ Focal plane indicator: Should you need to know the exact distance between your subject and the camera, the focal plane indicator labeled in Figure 1-6 is key. This mark indicates the plane at which light coming through the lens is focused onto the camera’s image sensor. Basing your measurement on this mark produces a more accurate camera-to-subject distance than using the end of the lens or some other point on the camera body as your reference point.

❯❯ Microphone: You can record movie audio via the built-in microphone, which picks up sound from the two clusters of holes labeled “Microphone” in Figure 1-6.

❯❯ Wi-Fi lamp: The Wi-Fi lamp turns on to show that you’re connected, and blinks at various rates to show that it is waiting, transferring data, or has a connection error. For more information on Wi-Fi, turn to the appendix.

Back-of-the-body controls

Traveling over the top of the camera to its back, you encounter the smorgasbord of controls shown in Figure 1-7.


FIGURE 1-7: Having lots of external buttons makes accessing the camera’s functions easier.


Some buttons have multiple “official” names because they serve multiple purposes depending on whether you’re taking pictures, reviewing images, recording a movie, or performing some other function. This book refers to these buttons by the first label you see in the following list (and in Figure 1-7) to simplify things. Again, though, the margin icons show you exactly which button to press.

Starting at the top-right corner of the camera back and working westward (well, assuming your lens is pointing north, anyway), here’s an introduction to the buttons and other controls on this side of the camera:

❯❯ AF Point Selection/Magnify button: In certain shooting modes, you press this button to specify which autofocus points or zones you want the camera to use when establishing focus. You can also use it in Live View or Movie mode to magnify the display to check focus. (Chapter 5 tells you about focusing features.) In Playback mode, covered in Chapter 9, you use this button to magnify the image display (thus the plus sign in the button’s magnifying glass icon).

❯❯ AE Lock/FE Lock/Index/Reduce button: During shooting, press this button to lock autoexposure (AE) settings, as covered in Chapter 4, and to lock flash exposure (FE), a feature detailed in Chapter 2.

This button also serves two image-viewing functions: It switches the display to Index mode, enabling you to see multiple image thumbnails at once. And if you magnify a photo, pressing the button reduces the magnification level.

❯❯ Live View/Movie button: Press this button to shift to Live View mode, which enables you to compose your pictures using the monitor instead of the viewfinder. When shooting movies, press the button to start and stop recording. (You must first set the On/Off/Movie switch to the Movie position.)

❯❯ Aperture/Exposure Compensation button: When you shoot in the M (manual) exposure mode, press and hold this button, then rotate the Main dial to choose the aperture setting, also known as the f-stop. In the other advanced exposure modes (P, Tv, and Av), you instead use the button and dial to apply Exposure Compensation, a feature that enables you to adjust the exposure. Chapter 4 discusses both issues.

❯❯ Q (Quick Control) button: Press this button to shift to Quick Control mode, which enables you to adjust major shooting settings quickly. See “Using Quick Control Mode,” later in this chapter, for help.

❯❯ Wi-Fi button: Pressing this button enables certain wireless communication features; again, see the appendix for an explanation of Wi-Fi operations.

❯❯ Memory-card access light: Labeled in Figure 1-7, this light glows while the camera is recording data to the memory card. Don’t power off the camera while the light is lit, or you may damage the card or camera.

❯❯ Set button and cross keys: Figure 1-7 points out the Set button and the four surrounding buttons, known as cross keys. These buttons team up to perform several functions, including choosing options from the camera menus. You use the cross keys to navigate through menus and then press the Set button to select a specific menu setting.

In this book, the instruction “Press the left cross key” means to press the one to the left of the Set button, “Press the right cross key” means to press the one to the right of the Set button, and so on.

During viewfinder photography – that is, when you’re using the viewfinder and not the monitor to frame your shots – the cross keys also have individual responsibilities, which are indicated by their labels:

Press the up cross key to change the White Balance setting. The White Balance control, explained in Chapter 6, enables you to ensure that colors are rendered accurately.

Press the right cross key to adjust the AF Operation mode. This option controls one aspect of the camera’s autofocus behavior, as outlined in Chapter 5.

Press the left cross key to change the Drive mode. The Drive mode settings enable you to switch the camera from single-frame shooting to continuous capture or any of the other drive modes. See Chapter 2 for details.

Press the down cross key to change the Picture Style. Chapter 6 explains Picture Styles, which you can use to adjust the color, contrast, and sharpness of your pictures.

For Live View and Movie shooting, the cross keys perform different actions, all related to autofocusing. See Chapter 5 for help.

❯❯ Playback button: Press this button to switch the camera into picture-review mode.

❯❯ Erase button: Sporting a trash can icon, the universal symbol for delete, this button lets you erase pictures from your memory card during playback. Chapter 9 has specifics.

❯❯

Info button: In Live View, Movie, and Playback modes, pressing this button changes the picture-display style.

During viewfinder photography, you can press the Info button to toggle between the Quick Control screen and electronic level. (These displays are explained later in this chapter.)

❯❯ Menu button: Press this button to display camera menus; press a second time to exit the menus. See the upcoming section “Ordering from Camera Menus” for help navigating menus.

And the rest …

The remaining external features of note are shown in Figure 1-8 and described in the following list:

❯❯ Wireless remote-control sensor: This sensor can pick up the signal from the optional Canon wireless remote-control unit. The part number is Canon RC-6 and sells for about $20.

You also have two other wireless remote-control options. If you have a smartphone or tablet that can run the Canon Connect app, you can use that device as a wireless remote; the appendix provides more information. Alternatively, you can buy the Canon Wireless Remote Control BR-E1 (about $50), which connects to your camera via Bluetooth, also detailed in the appendix. I bring them up now because unlike the RC-6 unit, these two tools don’t need to be aimed at the camera’s remote-control sensor to work.

❯❯ Lens-release button: Press this button to disengage the lens from the lens mount so that you can remove it from the camera. While pressing the button, rotate the lens toward the shutter-button side of the camera to dismount the lens.

❯❯ Flash button: Press this button to raise the built-in flash in the advanced exposure modes (P, Tv, Av, and M).

❯❯ Depth-of-Field Preview button: When you press this button, the image in the viewfinder (or, in Live View mode, on the monitor) offers an approximation of the depth of field that will result from your selected aperture setting, or f-stop. Depth of field refers to the distance over which the scene appears to be in focus. Chapter 5 provides details.

❯❯ Speaker: When you play a movie that contains audio, the sound comes wafting through these little holes.

❯❯ Connection ports: Hidden under two covers on the left side of the camera, you find inputs for connecting the camera to various devices. Open the smaller cover to access the connections for a wired remote control or external microphone. Under the larger door, you find a digital terminal for connecting the camera to your computer via USB and an HDMI out port that sends the signal from your camera to an HDMI-equipped TV. To use either feature, you need to purchase a cable to make the connection. For USB downloading, check the Canon website for the cables that will do the trick. For HDMI output, you can use any HD cable that has a Type-C connection one on end (the end that goes into the camera).

See Chapter 12 for help with displaying images on an HD television; Chapter 9 explains how to connect the camera via USB to download pictures to your computer. (Spoiler alert: Downloading via USB is probably not your cheapest or easiest option; instead, consider using a memory-card reader or taking advantage of wireless transfer.)

❯❯ NFC antenna: This label marks the spot that emits a signal than can be picked up by NFC-enabled smartphones and other smart devices. (NFC stands for Near Field Communication.) If your device has this feature, you can simply place it next to the antenna to initiate a wireless connection between it and the camera. See the appendix for information on this wireless feature.

FIGURE 1-8: Other important controls reside on the front and left side of the camera.


If you turn the camera over, you find a tripod socket (which enables you to mount the camera on a tripod that uses a ¼-inch screw), the chamber that holds the battery, and a connection port for attaching a Canon power adapter. See the camera manual for specifics on running the camera on AC power.
