Lens: Your camera accepts Canon EF and EF-S lenses; the 18–55mm or 18–135mm kit lenses sold as a bundle with the camera body falls into the EF-S category. If you want to buy a non-Canon lens, check the lens manufacturer’s website to find out which lenses work with your camera.
SD, SDHC, or SDXC memory card: The SD stands for Secure Digital; the HC and XC stand for High Capacity and eXtended Capacity. The different labels reflect how many gigabytes (GB) of data the card holds. SD cards hold less than 4GB; SDHC, 4GB to 32GB; and SDXC, more than 32GB. The 90D is compatible with UHS-II cards. These cards are blazingly fast and capable of handling data transfer rates needed to shoot 4K video. They are also great for still photography. Look for the Roman numeral II on the card label and a double row of contacts (refer to Figure 1-26, later in this chapter) to confirm that it is UHS-II.
With camera, lens, battery, and card within reach, take these steps:
1 Turn the camera off.
2 Attach a lens.First, remove the caps that cover the front of the camera and the back of the lens. Then locate the proper mount index, which is a mark on the camera’s lens mount that indicates how to align the lens with the camera body. Your camera has two of these markers, one red and one white, as shown in Figure 1-1. Which marker you use depends on the lens type:Canon EF-S lens: The white square is the mount index.Canon EF lens: The red dot is the mount index.Your lens also has a mount index; align that mark with the matching one on the camera body, as shown in Figure 1-1. Place the lens on the camera mount and rotate the lens toward the side of the camera that sports the white EOS logo (or, to put it another way, away from the shutter-button side of the camera). You should feel a solid click as the lens locks into place.FIGURE 1-1: Align the mounting index on the lens with the one on the camera body.
3 Insert the battery.The battery compartment is on the bottom of the camera. When inserting the battery, hold it with the contacts so they go in first and the Canon imprint facing out (toward the side of the camera with the memory card cover). Gently push the battery in until the gray lock clicks into place, then shut the compartment door.
4 Insert a memory card.Open the memory card door and orient the card so that the notched corner is on top and the label faces the back of the camera, as shown in Figure 1-2. Push the card gently into the slot and close the card door. The memory-card access light (refer to Figure 1-2) blinks a few times to let you know that the camera recognizes the card. (The light appears even when the camera is turned off.)FIGURE 1-2: Insert the memory card with the label facing the back of the camera.
5 Rotate the monitor to the desired viewing position.When you first take the camera out of its box, the monitor is positioned with the screen facing inward, protecting it from scratches and smudges. Gently lift the right side of the monitor up and away from the camera back. You can then rotate the monitor to move it into the traditional position on the camera back, as shown on the left in Figure 1-3, or swing the monitor out to get a different viewing angle, as shown on the right.FIGURE 1-3: Here are just two possible monitor positions.
6 Turn the camera on.Slide the Power switch (see Figure 1-4) to the On position.
7 Set the language, time zone, and date.When you power up the camera for the first time, the monitor displays a screen asking you to set the date, time, and time zone. The easiest way to adjust these settings is to use the touch screen, which is enabled by default. Just tap an option to select it and then tap the up/down arrows at the bottom of the screen to set the value for that option. Finally, tap OK to exit the screen.You also can adjust settings by using either multi-contoller. Press the left/right directional keys to highlight a setting, press the Set or center Joystick button to activate the option, press the up/down directional keys to change the value, and press Set or the center Joystick button again to finalize the change. The date/time information is included as metadata (hidden data) in the picture file. You can view metadata in some playback display modes (see Chapter 9) and in certain photo programs, including Canon Digital Photo Professional (see Chapter 10).FIGURE 1-4: Rotate the switch to On to power up the camera.
8 Adjust the viewfinder to your eyesight.This step is critical; if you don’t set the viewfinder to your eyesight, subjects that appear out of focus in the viewfinder might actually be in focus, and vice versa. If you wear glasses while shooting, adjust the viewfinder with your glasses on. You control viewfinder focus through the dial labeled in Figure 1-5. (In official lingo, it’s called the diopter adjustment dial.) After taking off the lens cap, follow these steps: Look through the viewfinder, press the shutter button halfway, and then release it.In dim lighting, the camera may suggest opening the flash; ignore that for now and concentrate on the lines that appear in the center of the frame and the row of data displayed at the bottom of the frame.Rotate the adjustment dial until the viewfinder markings and data appear sharpest.Ignore the scene you see through the lens; that won’t change because you’re not actually focusing the camera. If the markings turn off before you finish making your adjustments, give the shutter button another quick half-press and release to redisplay them.Can’t get the display sharp enough? You may need an adapter that enables further adjustment of the viewfinder. Look for an E-series dioptric adjustment lens adapter.FIGURE 1-5: Use this dial to adjust the viewfinder focus to your eyesight.
9 Select an exposure mode by pressing and holding the lock-release button and rotating the Mode dial (refer to Figure 1-4).The exposure mode determines how much control you have over various camera settings, as well as whether any special effects are applied. Chapter 2 explains the various exposure modes. For easiest operation, set the dial to Scene Intelligent Auto (A+ on the Mode dial), as shown Figure 1-4. Be aware, though, that some camera features are available only in the advanced shooting modes: P, Tv, Av, M, B, C1, and C2. The lock-release button is a handy feature that keeps you from accidentally turning the Mode dial when you aren’t intending to.
That’s all there is to it — the camera is now ready to go. The rest of this chapter familiarizes you with other major camera features and explains such basics as how to navigate menus, use the touch screen, and view and adjust camera settings.
Exploring External Camera Features
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 just 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. Note that not all buttons work
