111 f: Changing the Depth of Field When using an aperture with a high f/number or shooting in low light scenes, note that camera shake can occur. A higher aperture f/number will ma ke the shutter speed slower. Under low light, the shutter speed ca n be as long as 30 sec. In such cases, increase the ISO speed and hol d the camera steady or use a tripod. The depth of field depends not onl y on the aperture, but also on the lens and on the subject distance. Since wide-angle lenses have a wide depth of field (range of acceptable focus in front of and beh ind the point of focus), you need not set a high aperture f/number to obtain a sharp picture from the foreground to the background. On the other hand, a telephoto lens has a narrow depth of field. And the closer the subject, the narro wer the depth of field. A farther subject will have a wider depth of field. Set the aperture so that the shutter speed display does not blink. If you press the shutter button halfway and change the aperture while the shutter speed is displayed, the shutter speed display will also change to maintain the same exposure (amount of light reaching the image sensor). If you exceed the adjustable shutter speed range, the shutter speed display will blink to indicate that the standard exposure cannot be obtained. If the picture will be too dark, the “ 30” (30 sec.) shutter speed display will blink. If th is happens, turn the < 6> dial to the left to set a lower aperture f/number or increase the ISO speed. If the picture will be too bright, the “ 4000” (1/4000 sec.) shutter speed display will blink. If this happens, turn the < 6> dial to the right to set a higher aperture f/number or decrease the ISO speed. Shooting Tips COPY
112 f: Changing the Depth of Field To obtain a correct flash expos ure, the flash output will be set automatically to match the set a perture (autoflash exposure). The shutter speed will be set automatically between 1/200 sec. - 30 sec. to suit the scene’s brightness. In low light, the main subject is ex posed with the automatic flash, and the background is exposed with a slow shutter speed set automatically. Both the subject and background look properly exposed (automatic slow-speed flash sync). If you ar e handholding the camera, keep it steady to prevent camera shake. Using a tripod is recommended. To prevent a slow shutter speed, under [ z1: Flash control ], set [Flash sync. speed in Av mode] to [ 1/200-1/60 sec. auto] or [1/200 sec. (fixed) ] (p.215). The aperture opening (diaphragm) changes only at the moment when the picture is taken. Otherwise, the aperture remains fully open. Therefore, when you look at the sce ne through the viewfinder or on the LCD monitor, the depth of field will look narrow. Press the depth-of-field preview button to stop down the lens to the current aperture setting and check the depth of field (range of acceptable focus). D Using the Built-in Flash Depth of Field Preview N While looking at the Live View image (p.144) and ho lding down the depth-of- field preview button, you can change th e aperture and see how the depth of field changes.

113 You can set both the shutter speed and aperture manually as desired. While referring to the exposure level indicator in the viewfinder, you can set the exposure as desired. This method is called manual exposure. * < a> stands for Manual. 1Set the Mode Dial to < a>. 2Set the shutter speed and aperture. To set the shutter speed, turn the dial. To set the aperture, hold down the button and turn the < 6> dial. 3Focus the subject. Press the shutter button halfway. X The exposure setting will be displayed in the viewfinder. The exposure level mark < h> indicates how far the current exposure level is from the standard exposure level. 4Set the exposure and take the picture. Check the exposure level and set the desired shutter speed and aperture. If the exposure compensation amount exceeds ±2 stops from the standard exposure, the end of the exposure level indicator will display < I> or in the viewfinder. (On the LCD monitor, if the exposure level exceeds ±3 stops, < I> or will be displayed.) a : Manual Exposure + Exposure level markStandard exposure index COPY
114 a: Manual Exposure To obtain a correct flash expos ure, the flash output will be set automatically (autoflash exposure) to match the manually-set aperture. The shutter speed can be set from 1/200 sec. to 30 sec. A bulb exposure keeps the shutter open for as long as you hold down the shutter button. It can be used to photograph fireworks and other subjects requiring long exposures. In step 2 on the preceding page, turn the dial to the left to set < BULB>. The elapsed exposure time will be displayed on the LCD monitor. I Using the Built-in Flash BULB: Bulb Exposures In [z2: Auto Lighting Optimizer ], if the checkmark for [Disable during man expo ] is removed, it can be set in the mode (p.123). When ISO Auto is set, you can press the button to lock the ISO speed. After recomposing the picture, you can see the exposure level difference on the exposure level in dicator (p.22, 23) compar ed to when you pressed the < A> button. During the bulb exposure, do not po int the lens toward the sun. The sun’s heat can dam age the camera’s in ternal components. Since bulb exposures produce more noise than usual, the image may look a little grainy. When [z 3: Long exp. noise reduction ] is set to [Auto] or [Enable ], noise generated by the long ex posure can be reduced (p.125). For bulb exposures, using a tripod and Remote Switch (sold separately, p.304) is recommended. You can also use a remote controller (sold separately, p.303) for bulb exposures. When you press the remote controller’s transmit button, the bulb exposure will star t immediately or 2 sec. later. Press the button again to stop the bulb exposure. COPY
115 Four methods (metering modes) to measure the subject’s brightness are provided. Normally, evaluative metering is recommended. In Basic Zone modes, evaluative metering is set automatically. 1Select [Metering mode]. Under the [ z2] tab, select [Metering mode ], then press < 0>. 2Set the metering mode. Select the metering mode, then press . q Evaluative metering This is a general-purpose metering mode suited even for backlit subjects. The camera sets the exposure automatically to suit the scene. w Partial metering Effective when the background is much brighter than the subject due to backlighting, etc. The gray area in the left figure is where the brightness is metered to obtain the standard exposure. r Spot metering This is for metering a spec ific part of the subject or scene. The gray area in the left figure is where the brightness is metered to obtain the standard exposure. This metering mode is for advanced users. q Changing the Metering Mode N COPY
116 q Changing the Metering Mode N e Center-weighted average metering The brightness is metered at the image center and then averaged for the entire scene. This metering mode is for advanced users. With q (evaluative metering) and e (center-weighted average metering), the metering range is almo st the same as with viewfinder shooting. With w (partial metering) and r (spot metering), the metering range slightly differs from view finder shooting. The approximate metering ranges are as shown below: * The figures show when [ Grid 2 m] is set. The meteri ng ranges are not displayed on the LCD monitor. Metering Range During Live View Shooting Partial metering Spot metering With q (evaluative metering) during viewfinder shooting, the exposure setting will be locked when you press the shutter button halfway and focus is achieved. With w (partial metering), r (spot metering), and e (center- weighted average metering), exposure setting is set at the moment of exposure. (The exposure setting is no t locked when you press the shutter button halfway.) During Live View shooting, the exposure setting is set at the moment of exposure, regardless of the me tering mode setting. COPY
117 Set exposure compensation if the exposure (without flash) does not come out as desired. This feature can be used in Crea tive Zone modes (except ). You can set the exposure compensation up to ±5 stops in 1/3-stop increments. Making it brighter: Hold down the < O> button and turn the < 6> dial to the right. (Increased exposure) Making it darker: Hold down the < O> button and turn the < 6> dial to the left. (Decreased exposure) X As shown in the figure, the exposure level is displayed on the LCD monitor and in the viewfinder. After taking the picture, cancel the exposure compensation by setting it back to 0. Setting Exposure Compensation N O Setting Exposure Compensation Increased exposure for a brighter image Decreased exposure for a darker image The exposure compensation amount displayed in the viewfinder goes up to only ±2 stops. If the exposure compensation amount exceeds ±2 stops, the end of t he exposure level indicator will display < I> or . If you want to set exposu re compensation exceedin g ±2 stops, setting it with [ z2: Expo.comp./AEB ] (p.119) or with the Quick Control screen (p.44) is recommended. Dark exposure Increased expo sure for a brighter image COPY
118 Setting Exposure CompensationN Set flash exposure compensation if the flash exposure of the subject does not come out as desired. You can set the exposure compensation up to ±2 stops in 1/3-stop increments. 1Press the button. (7 ) X The Quick Control screen will appear (p.44). 2Select [ y]. Press the < S> key to select [ y*]. X [Flash exposure comp.] will be displayed at the bottom. 3Set the exposure compensation amount. To make the flash exposure brighter, turn the < 6> dial to the right (increased exposure). To make it darker, turn the dial to the left (decreased exposure). X When you press the shutter button halfway, the < y> icon will appear in the viewfinder. After taking the picture, cancel the flash exposure compensation by setting it back to 0. y Flash Exposure Compensation If [z 2: Auto Lighting Optimizer ] (p.123) is set to any setting other than [ Disable ], the image may look bright even if a decreased exposure compensation or decr eased flash exposure compensation is set. You can also set flash exposure compensation with [ Built-in flash settings] in [z 1: Flash control ] (p.216). COPY
119 This feature takes exposure compensation a step further by varying the exposure automatically (up to ±2 stops in 1/3-stop increments) with three shots as shown below. You can then choose the best exposure. This is called AEB (Auto Exposure Bracketing). 1Select [Expo.comp./AEB]. Under the [ z2] tab, select [Expo.comp./AEB], then press . 2Set the AEB range. Turn the < 6> dial to set the AEB range. Press the < U> key to set the exposure compensation amount. If AEB is combined with exposure compensation, AEB will be applied centering on the exposure compensation amount. Press < 0> to set it. When you press the < M> button to exit the menu, the AEB range will be displayed on the LCD monitor. 3Take the picture. Focus and press the shutter button completely. The three bracketed shots will be taken in this sequence: standard exposure, decreased exposure, and increased exposure. 3 Auto Exposure Bracketing N Standard exposure Darker exposure (Decreased exposure) Brighter exposure (Increased exposure) AEB range COPY
120 3 Auto Exposure BracketingN Follow steps 1 and 2 to turn off the AEB level display. The AEB setting will also be cancel ed automatically if the power switch is set to < 2>, flash recycling is completed, etc. Using AEB with continuous shooting If continuous shooting (p.101) is set and you press the shutter button completely, the three bracketed shots will be taken continuously in this sequence: standard exposure, decreased exposure, and increased exposure. Using AEB with < u> single shooting Press the shutter button three time s to take the three bracketed shots. The three bracketed shots will be exposed in the following sequence: standard exposure, decreased exposure, and increased exposure. Using AEB with the self-timer or a remote controller (sold separately) With the self-timer or a remote control shooting (< Q> or < l>), you can take three continuous shots after a 10-sec. or 2-sec. delay. With < q> (p.103) set, the number of co ntinuous shots will be three times the number set. Canceling AEB Shooting Tips AEB cannot be used with flash, [Multi Shot Noise Reduction ], or bulb exposures. If [z 2: Auto Lighting Optimizer ] (p.123) is set to any setting other than [ Disable ], the AEB’s effect may be minimal. COPY
