151 A Menu Function Settings Aspect ratio N The image’s aspect ratio can be set to [ 3:2], [4:3], [ 16:9], or [ 1:1]. The area surrounding the Live Vi ew image is masked in black when the following aspect ratios are set: [ 4:3] [16:9] [ 1:1]. JPEG images will be saved with the set aspect ratio. RAW images will always be saved with the [ 3:2] aspect ratio. Since the aspect ratio information is appended to the RAW image, the image will be generated in the respective aspect ratio when you process the RAW image with the provided software. In the case of the [ 4:3], [16:9], and [1:1] aspect ratios, the aspect-ratio lines will appear during image playback, but the lines are not actually drawn on the image.

If you use a different camera to directly print images shot with this camera in the 1:1 aspect ratio, the images may not be correctly printed. COPY
152 A Menu Function Settings Metering timer N You can change how long the exposure setting is displayed (AE lock time). In Basic Zone modes, metering timer is fixed at 16 sec. The Live View shooting will stop with any of the following operations. To resume Live View shooting, press the < A> button again. • When selecting [ z3: Dust Delete Data ], [53: Sensor cleaning ], [ 5 4: Clear settings], or [ 54: z firmware ver.] • When changing the shooting modes (Basic Zone modes ↔ Creative Zone modes, setting to or mode) Even if a low ISO speed is set, noise may be noticeable in the displayed Live View image under low light. Ho wever, when you shoot, the image recorded will have minimal noise. (T he image quality of the Live View image is different from t hat of the recorded image.) COPY
153 You can select the AF method suiting the shooting conditions or subject. The following AF methods are provided: [u(face)+Tracking], [FlexiZone - Multi] (p.155), [FlexiZone - Single] (p.156), and [Quick mode] (p.160). AF methods other than the [ Quick mode] use the image sensor to autofocus while displaying the Live View image. Select the AF method. Under the [A] tab, select [AF method].

If the focus is far off, face detect ion will not be possible. If you set [ Continuous AF ] to [Enable ], you can prevent the image from becoming greatly out of focus. An object other than a human fa ce may be detected as a face. Face detection will not wo rk if the face is very small or large in the picture, too bright or too dark, or partially hidden. The < p> may cover only part of the face. If you press < 0> or the < L> button, the AF point < > will appear at the center and you can use the < S> keys to move the AF point. If you press < 0> or the < L> button again, the AF point will move to the detected subject. Since AF is not possible with a face detected near the edge of the picture, the will be grayed out. If you press the shutter button halfway, the subject will be focused in FlexiZ one - Multi method with automatic selection. COPY
155 Changing the Autofocus Method (AF Method) Up to 31 AF points (automatically selected) covering a wide area can be used to focus. This wide area can also be divided into 9 zones for focusing (zone selection). 1Display the Live View image. Press the < A> button. X The Live View image will appear on the LCD monitor. 2Select the AF zone. N Pressing < 0> or the < L> button will toggle between automatic selection and zone selection.

X When focus is achieved, the AF point will turn green a nd the beeper will sound. X If focus is not achieved, the area frame will turn orange. 4Take the picture. Check the focus and exposure, then press the shutter button completely to take the picture (p.144). Since only one AF point is used to fo cus, you can focus the target subject. 1Display the Live View image. Press the < A> button. X The Live View image will appear on the LCD monitor. X The AF point < > will appear. During movie shooting, if [ Movie servo AF] is set to [ Enable], the AF point will be displayed in a larger size. FlexiZone - Single: d When the camera does not focus the desired target subject with automatic AF point selectio n, switch the AF method to zone selection or [ FlexiZone - Single ], and refocus. Depending on the aspect ratio setting, the number of AF points will differ. At [3:2 ], there will be 31 AF points. At [1:1] and [ 4:3], there will be 25 AF points. And at [ 16:9], 21 AF points. Also, at [16:9 ], there will be only three zones. For movie shooting, there will be 21 AF points (or 25 AF points if [ 640x480 ] is set) and three zones (or 9 zones if [ 640x480] is set). AF point COPY
157 Changing the Autofocus Method (AF Method) 2Move the AF point. Press the < S> key to move the AF point to where you want to focus. (It cannot go to the edges of the picture.) To return the AF point to the center, press < 0> or the < L> button. You can also tap the LCD monitor screen to move the AF point. 3Focus the subject. Aim the AF point over the subject and press the shutter button halfway. X When focus is achi eved, the AF point will turn green a nd the beeper will sound.

158 Changing the Autofocus Method (AF Method) AF Operation Focusing will take longer than with [ Quick mode]. Even when focus has been achieved, pressing the shutter button halfway will focus again. The image brightness may change du ring and after the AF operation. If the light source changes while th e Live View image is displayed, the screen may flicker and focusing may be difficult. If this happens, exit Live View shooting and autofocus under the actual light source. When [FlexiZone - Multi ] is set and you press the < u> button (or tap < > on the screen), the center of the selected zone (or image center with automatic selection) will be magnified. If you press the shutter button halfway, the display will return to normal and the camera will focus. When [ FlexiZone - Single ] is set and you press the < u> button (or tap < > on the screen), the area cover ed by the AF point will be magnified. Press the shutter butt on halfway to focus while in the magnified view. This is effective w hen the camera is attached to a tripod and you need to attain very pr ecise focus. If focusing is difficult in the magnified view, return to th e normal display and use AF. Note that the AF speed may differ betw een the normal and magnified views. If you magnify the view after focusing with [ FlexiZone - Multi] or [FlexiZone - Single ] in the normal view, it may not look focused. If [u+Tracking ] is set, magnified view is not possible. Notes About [u+Tracking], [FlexiZone - Multi], and [ FlexiZone - Single] If you shoot a peripheral subject and it is slightly out of focus, aim the center AF point or zone over the subject to focus, focus again and then take the picture. The AF-assist beam will not be em itted. However, if an EX-series Speedlite (sold separately) equipped with an LED light is used, the LED light will turn on for AF-assist when necessary. In magnified view, the higher the magnification, the more difficult focusing will be because of camera shake when shooting hand-held (as well as when the lens focus mode switch is set to ). Using a tripod is recommended. COPY
159 Changing the Autofocus Method (AF Method) Shooting conditions that make focusing difficult Low-contrast subjects such as the blue sky, solid-color flat surfaces or when highlights or shadow details are lost. Subjects in low light. Stripes and other patterns where there is contrast only in the horizontal direction. Subjects with repetitive pattern s (skyscraper windows, computer keyboards, etc.). Fine lines and subject outlines. Under a light source whose brightness, color, or pattern keeps changing. Night scenes or points of light. When the image flickers under fluorescent or LED light sources. Extremely small subjects. Subjects at the edge of the picture. Subjects strongly reflecting light. The AF point covers both a near and faraway subject (such as an animal in a cage). Subjects that keep moving withi n the AF point and cannot keep still due to camera shake or subject blur. A subject approaching or moving away from the camera. Autofocusing while the subject is very far out of focus. Soft focus effect is applied with a soft focus lens. A special effect filter is used. If focus is not achieved with the above shooting conditions, set the lens focus mode switch to < MF> and focus manually. If you use AF with any of the following lenses, using [ Quick mode] is recommended. Autofocusing with [ u+Tracking ], [FlexiZone - Multi ] or [ FlexiZone - Single ] may take longer or co rrect focus may not be achieved. • EF24mm f/2.8 • EF28-90mm f/4-5.6 III • EF35mm f/2 • EF55-200mm f/4.5-5.6 USM • EF50mm f/2.5 Compact Ma cro • EF90-300mm f/4.5-5.6 • EF100mm f/2.8 Macro • EF 90-300mm f/4.5-5.6 USM • EF135mm f/2.8 (SoftFocus) COPY
160 Changing the Autofocus Method (AF Method) The dedicated AF sensor is used to focus in One-Shot AF operation (p.95), using the same AF method as with viewfinder shooting. You can use nine AF points to focus (automatically selected). You can also select one AF point to focus and focus only the area covered by that AF point (manually selected). Although you can focus the target subject quickly, the Live View image will be interrupted momentarily during the AF operation. 1Display the Live View image. Press the < A> button.
