101 S S ISO Sensitivity “ISO sensitivity” is the digital equivalent of film speed. Choose from settings that range from a value roughly equivalent to ISO 100 to one roughly equivalent to ISO 6400 in steps equivalent to 1/3EV. For special situations, ISO sensitivity can be raised above ISO 6400 by from about 0.3 EV (Hi 0.3, equivalent to ISO 8000) to about 2 EV (Hi 2, equivalent to ISO 25600). Auto and scene modes also offer an AUTO option, which allows the camera to set ISO sensitivity automatically in response to lighting conditions. The higher the ISO sensit ivity, the less light needed to make an exposure, allowing higher shutter speeds or smaller apertures. ISO sensitivity can be adjusted by pressing the ISO button and rotating the main command dial until the desired setting is displayed in the control panel or viewfinder. ISO button Main command dial Control panel Viewfinder
102 S AAUTO If the mode dial is rotated to P, S, A , or M after AUTO is selected for ISO sensitivity in another mode, the ISO sensitivity last selected in P, S, A , or M mode will be restored. AHi 0.3–Hi 2 Pictures taken at these settings are more like ly to be subject to noise (randomly-spaced bright pixels, fog, or lines). ASee Also For information on choosing the ISO sensitiv ity step size, see Custom Setting b1 (ISO sensitivity step value ; 0 211). For information on using the High ISO NR option in the shooting menu to reduce noise at high ISO sensitivities, see page 205. AThe Shooting Menu ISO sensitivity can also be adjusted using the ISO sensitivity settings option in the shooting menu ( 0202).
103 S Auto ISO Sensitivity Control If On is selected for ISO sensitivity settings > Auto ISO sensitivity control in the shooting menu, ISO sensitivity will automatica lly be adjusted if optimal exposure can not be achieved at the value selected by the user (ISO sensitivity is adjusted appropriately when the flash is used). 1Select Auto ISO sensitivity control . Press the G button and select ISO sensitivity settings in the shooting menu. Highlight Auto ISO sensitivity control and press 2. 2Select On. Highlight On and press J (if Off is selected, ISO sensitivity will remain fixed at the value selected by the user). 3Adjust settings. The maximum value for auto ISO sensitivity can be selected using Maximum sensitivity (choose lower values to prevent noise in the form of randomly-spaced bright pixels, fog, or lines); the minimum value for auto ISO sensitivity is automatically set to ISO 100. In modes P and A, sensitivity will only be adjusted if underexposure would result at the shutter speed selected for Minimum shutter speed ( 1/4000–1 s; in modes S and M, sensitivity will be adjusted for optimal exposure at the shutter speed selected by the user). Slower shutter speeds will be used only if optimum exposure can not be achieved at the ISO sensitivity value selected for Maximum sensitivity. If the ISO sensitivity selected by the user is higher than the value selected for Maximum sensitivity , the value selected for Maximum sensitivity will be used instead. (P, S, A, and M Modes Only) G button
104 S Press J to exit when settings are complete. When On is selected, the display at right appears in the viewfinde r and control panel. When sensitivity is altered from the value selected by the user, these indicators blin k and the altered value is shown in the information display. AAuto ISO Sensitivity Control Noise is more likely at hi gher sensitivities. Use the High ISO NR option in the shooting menu to reduce noise (see page 205). When a flash is used, the value selected for Minimum shutter speed is ignored in favor of the option selected for Custom Setting e1 ( Flash sync speed , 0 222). Note that ISO sensitivity may be raised automatically when auto ISO sensitivity control is used in combination with slow sync flash modes (available with the built-in flash and SB-900, SB-800, SB-700 , SB-600, and SB-400 flash units), possibly preventing the camera from selecting slow shutter speeds.
105 Z Z Exposure/Bracketing Choose how the camera sets exposure in P, S, A , and M modes (in other modes, the camera selects the metering method automatically). To choose a metering option, press the Z button and rotate the main command dial until the desired setting is displayed in the control panel. Metering OptionDescription a Matrix : Produces natural results in most situations. Camera meters a wide area of the frame and set exposure according to tone dist ribution, color, composition, and, with type G or D lenses ( 0269), distance information (3D color matrix metering II; with other CPU lenses, camera uses color matrix metering II, which does not include 3D distance information). With non-CPU lenses, camera uses color matrix metering if focal length and maximum apertu re are specified using Non-CPU lens data option in setup menu ( 0159); otherwise camera uses center-weighted metering. Z Center-weighted : Camera meters entire frame but assigns greatest weight to center area (if CPU lens is attached, size of area can be selected using Custom Setting b4, Center- weighted area , 0 213; if non-CPU lens is attached, area is 8 mm in diameter). Classic meter for portraits; recommended when usin g filters with an exposure factor (filter factor) over 1×. * b Spot : Camera meters circle 3.5 mm (0.14 in.) in diameter (approximately 2.5% of frame). Circle is centered on current focus point, maki ng it possible to meter off-center subjects (if non-CPU lens is used or if auto-area AF is in effect, camera will meter center focus point). Ensures that subject will be correctly exposed, even when background is much brighter or darker.* * For improved precision with non-CPU lenses, specify lens focal length and maximum aperture in Non-CPU lens data menu (0159). ASee Also For information on making separate adjustments to optimal exposure for each metering method, see Custom Setting b5 ( Fine tune optimal exposure , 0 213).

106 Z Autoexposure Lock Use autoexposure lock to recompose photographs after metering exposure: 1Set metering to Zor b (0 105). Choose Z to assign the greatest weight to the center of frame, or b to set exposure for a 3.5-mm circle centered on the active focus point. a will not produce the desired results. 2Lock exposure. Position the subject in the selected focus point and press the shutter-release button halfway. With the shutter-release button pressed halfway and the subject positione d in the focus point, press the AE-L/AF-L button to lock focus and exposure (if you are using autofocus, confirm that the I in-focus indicator appears in the viewfinder). While exposure lock is in effect, an AE-L indicator will appear in the viewfinder. 3Recompose the photograph. Keeping the AE-L/AF-L button pressed, recompose the photograph and shoot. AAdjusting Shutter Speed and Aperture While exposure lock is in effect, the following settings can be adjusted without altering the metered value for exposure: ModeSetting P Shutter speed and aperture (flexible program; 068) S Shutter speed A Aperture The new values can be confirmed in the viewfinder and control panel. Note that metering can not be changed while exposure lock is in effect. ASee Also If On is selected for Custom Setting c1 ( Shutter-release button AE-L, 0 213), exposure will lock when the shutter-release button is pressed halfway. For information on changing the role of the AE-L/AF-L button, see Custom Setting f5 ( Assign AE-L/AF-L button, 0 232). Shutter-release button AE-L/AF-L button
107 Z Exposure Compensation Exposure compensation is used to alter exposure from the value suggested by the camera, making pictures brighter or darker. It is most effective when used with center-weighted or spot metering ( 0105). Choose from values between –5 EV (underexposure) and +5 EV (overexposure) in increments of 1/3EV. In general, positive values make the subject brighter while negative values make it darker. To choose a value for exposu re compensation, press the E button and rotate the main co mmand dial until the desired value is displayed in the control panel or viewfinder. At values other than ±0.0, the 0 at the center of the exposure indicators will flash (modes P, S, and A only) and a E icon will be displayed in the control panel and viewfinder after you release the E button. The current value for exposure compensation can be confirmed in the exposure indicator by pressing the E button. Normal exposure can be restored by setting exposure compensation to ±0. Exposure compensation is not reset when the camera is turned off. –1 EV No exposure compensation +1 EV ±0 EV ( E button pressed) –0.3 EV +2.0 EV (P, S, A, and M Modes Only) E button Main command dia l
108 Z AMode M In mode M, exposure compensation affects only the exposure indicator; shutter speed and aperture do not change. AUsing a Flash When a flash is used, exposure compensation affects both background exposure and flash level. ASee Also For information on choosing the size of the increments available for exposure compensation, see Custom Setting b2 ( EV steps for exposure cntrl., 0 211). For information on making adjustments to ex posure compensation without pressing the E button, see Custom Setting b3 ( Easy exposure compensation, 0 212). For information on automatically varying exposure, flash level, white balance, or Active D-Lighting, see page 109.
109 Z Bracketing Bracketing automatically varies exposure, flash level, Active D-L ighting (ADL), or white balance slightly with each shot, “bracketing” the current value. Choose in situations in which it is difficult to set ex posure, flash level, white balance, or Active D-Lighting and there is not time to check results and adjust settings with each shot, or to experiment with different settings for the same subject. ❚❚ Exposure and Flash Bracketing To vary exposure and/or flash level over a series of photographs: 1Select exposure or flash bracketing. To display the menus, press the G button. Select Custom Setting e5 ( Auto bracketing set ) in the Custom Settings menu, highlight an option, and press J. Choose AE & flash to vary both exposure and flash level, AE only to vary only exposure, or Flash only to vary only flash level. 2Choose the number of shots. Pressing the D button, rotate the main command dial to choose the number of shots in the bracketing sequence and the order in which they will be taken. D will be displayed in the viewfinder (see right); the control panel will show M.

110 Z 3Select the bracketing increment. Pressing the D button, rotate the sub-command dial to choose from values between 0.3 EV and 2 EV. 4Frame a photograph, focus, and shoot. The camera will vary exposure and/or flash level shot-by- shot according to the bracketing program selected. Modifications to exposure are added to those made with exposure compensation ( 0107), making it possible to achieve exposure compensation values of more than 5 EV. While bracketing is in effect, a bracketing progress indicator will be displayed in the control panel. A segment will disappear from the indicator after each shot: the y segment when the unmodified shot is taken, the z segment when the shot with the negative increment is taken, and the x segment when the shot with the positive increment is taken. To cancel bracketing, press the D button and rotate the main command dial until the bracketing progress indicator and M icon are no longer displayed.
