Using Built-In Speedlight When the subject is dark or backlit (except in d or g) and the shutter release button is lightly pressed, the built-in Speedlight automatically pops up in a (AUTO mode) or Vari-Program (s, d, f, g, h). Fully depress the shutter release button to take pictures with the Speedlight. 1 When the subject is dark or backlit and the shutter release button is lightly pressed, the built-in Speedlight automatically pops up and starts charging. • When the Speedlight is ready to fire, fi appears without blinking in the viewfinder (when the camera's meter is on). • When you want to take a picture without the flash, close the Speedlight until it clicks shut while lightly pressing the shutter release button. (When the flash is cancelled in this manner, as long as the shutter release button is kept lightly pressed, flash is cancelled for subsequent shots. When you remove your finger from the shutter release button and shutter release button is lightly pressed again, the built-in Speedlight pops up again and flash starts charging.) • To cancel the flash for subsequent shots, select the Flash Cancel mode (page 79). • When the subject is backlit in d or g mode, built-in Speedlight does not fire automatically. NOTE: Continuous use of built-in Speedlight After continuous use of the built-in Speedlight, it may stop firing to protect the firing tube. Wait for a while before using the Speedlight again. 34 2 Confirm fi in viewfinder, then compose, focus and take the picture with flash by fully depressing the shutter release button. • The shutter cannot be released unless fi appears without blinking in the viewfinder. • fi blinks in the viewfinder approx. 3 sec. after full flash output. If this happens, underexposure may have occurred. Check the flash shooting distance range (page 84) and shoot again. • With dark subjects, the camera's AF-Assist Illuminator is automatically activated to guide autofocus. See page 48 for details. Built-in Speedlight and Matrix Balanced Fill-Flash • The built-in Speedlight offers an angle of coverage of 28mm lens with a guide number of 12 (ISO 100, m). When a wide-angle lens of less than 28mm focal length is used in flash photography using the built-in Speedlight, the flash may not reach the peripheral area and may result in a dark picture. • Using CPU Nikkor lenses such as a D- or G-type Nikkor lens enables use of Matrix Balanced Fill-Flash. Analysing the brightness and contrast level derived from Matrix Metering, the Matrix Balanced Fill-Flash ensures proper exposure of the main subject and background, while providing adequate flash output to create natural-looking flash photography. See page 76 for details. Check points • Be sure to remove (or store) the lens hood before flash shooting. • Some lenses have limitations using the built-in Speedlight and may cause vignetting (a shadow may appear within the frame) (page 85). • Normal Front-Curtain Sync flash mode is introduced in this section. Various flash sync modes are also available. For details, see page 78. 35 BASIC OPERATION
