M: Manual In manual mode, you control both shutter speed and aperture. While the exposure meters are on, rotate the main command dial to choose a shutter speed, and the sub-command dial to set aperture. Shutter speed can be set to "v" or to values between 30 s and 1/8000 s, or the shutter can be held open indefinitely for a long time-exposure (Bulb/A or Time/%, 0 52). Aperture can be set to values between the minimum and maximum values for the lens. Use the exposure indicators to check exposure. Shutter speed Aperture # Main command dial Sub-command dial A AF Micro NIKKOR Lenses Provided that an external exposure meter is used, the exposure ratio need only be taken into account when the lens aperture ring is used to set aperture. A The Exposure Indicator If a shutter speed other than Bulb (A) or Time (%) is selected, the exposure indicator in the viewfinder shows whether the photograph would be under- or over-exposed at current settings. Depending on the option chosen for Custom Setting b2 (EV steps for exposure cntrl, 0 234), the amount of under- or over-exposure is shown in increments of 1/3 EV or 1/2 EV (the illustrations below show the display in the viewfinder when 1/3 step is selected for Custom Setting b2). If the limits of the exposure metering or live view exposure control system are exceeded, the indicator will flash. Optimal exposure Underexposed by 1/3 EV Overexposed by over 2 EV A See Also For information reversing the exposure indicators so that negative values are displayed on the right and positive values on the left, see Custom Setting f8 (Reverse indicators, 0 258). 51
