Built-In Speedlight/Ready-Light • Built-in Speedlight and TTL Flash modes This camera is equipped with a built-in Speedlight that provides an angle of coverage for a 28mm lens with a guide number of 12 (ISO 100, m). When the subject is dark or backlit, in a or Vari-Program (except in d or g), the builtin Speedlight automatically pops up. When the shutter is released, the flash fires to create natural-looking flash photography utilising 3D Multi-Sensor Balanced Fill-Flash or Multi-Sensor Balanced Fill-Flash. In P, S, A or M exposure mode, when the subject is dark or backlit, flash recommended indication ‡ blinks in the viewfinder, and the Speedlight pops up when the Speedlight lock-release button is pressed and the 3D MultiSensor Balanced Fill-Flash or Multi-Sensor Balanced Fill-Flash is possible. (In M exposure mode, Standard TTL Flash is selected.) In addition to shooting in dim light, the flash can be used in daylight to reduce shadows on the main subject or to put catchlights in your subject's eyes. Five flash sync modes-Front-Curtain Sync (Normal Sync), Slow Sync, Rear-Curtain Sync, Red-Eye Reduction and Red-Eye Reduction with Slow Sync-are available with this camera. • See below for the TTL Flash modes, page 95 for using the built-in Speedlight and page 92 for the flash sync modes. • The following TTL Auto Flash modes are available with built-in Speedlight depending on the type of lens used. Lens TTL Auto Flash mode D- or G-type Nikkor lens 3D Multi-Sensor Balanced Fill-Flash*1 (with Distance Information and Monitor Pre-Flash*2) CPU Nikkor lens other than D/Gtype (except AF Nikkor for F3AF) Multi-Sensor Balanced Fill-Flash*1 (with Monitor Pre-Flash*2) Non-CPU Nikkor lens Standard TTL*3 *1 When built-in Speedlight is used and the exposure mode is set to Manual, TTL Auto Flash mode automatically changes to Standard TTL Flash. *2 To cancel Monitor Pre-Flash, select Manual exposure mode. *3 Monitor-Pre Flash is not fired in Standard TTL Flash. 90 3D Multi-Sensor Balanced Fill-Flash • 3D Multi-Sensor Balanced Fill-Flash is automatically set in a, Vari-Program, P, S or A exposure mode with D- or G-type Nikkor lens attached. In this flash mode, just after you press the shutter release button and before the shutter is activated, the built-in Speedlight will fire a series of imperceptible preflashes that are detected by the F75/F75D's fivesegment TTL Multi Sensor, then analysed for brightness and contrast. Furthermore, it integrates Distance Information from the lens with other exposure control information, automatically compensating the flash output level so that flash output and ambient light are balanced. 3D Multi-Sensor Balanced Fill-Flash enables flash photography in very difficult situations, such as a scene that includes an object with extremely high reflectivity or a subject against an "infinite" background (empty sky, clouds, etc.). Multi-Sensor Balanced Fill-Flash • Multi-Sensor Balanced Fill-Flash, without the Distance Information added to the 3D Multi-Sensor Balanced Fill-Flash, can be performed with a combination of the F75/F75D camera and CPU Nikkor lens other than D/G-type. 3D Multi-Sensor Balanced Fill-Flash together with Multi-Sensor Balanced Fill-Flash is called Automatic Balanced Fill-Flash with TTL Multi Sensor Standard TTL Flash • Standard TTL Flash is automatically selected when the exposure mode is set to M. In Standard TTL Flash, the main subject is correctly exposed but background exposure is not considered. Standard TTL Flash is useful when you want to highlight the main subject. • Ready-light • When using the built-in Speedlight or an optional Speedlight (p. 107), the ready-light ‡ appears in the viewfinder when the Speedlight is fully charged and ready to fire. • If the ready-light ‡ blinks approx. 3 sec. after full flash output, underexposure may have occurred. Check the focus distance, aperture or flash shooting distance range (p. 98) and shoot again. www.mynikon.com.pl 91 Speedlight
