Nikon F 100 instruction manual Types of TTL Auto Flash

Types of TTL Auto Flash

•When an optional Nikon Speedlight is attached and set to TTL mode, the following TTL Auto Flash modes are available depending on the type of lens used.

Multi-Sensor Balanced Fill-Flash/3D Multi-Sensor Balanced Fill-Flash

(Automatic Balanced Fill-Flash with TTL Multi Sensor)

Automatic Balanced Fill-Flash with TTL Multi Sensor can be performed with a combination of the F100 camera, a CPU lens and the Nikon TTL AF Speedlight. In this flash mode, just after you press the shutter release button and before the shutter is activated, the Speedlight with Monitor Pre-Flash function (SB-80DX, SB-50DX, SB-28/ 28DX, SB-27, SB-26 and SB-25) will fire a series of imperceptible pre-flashes that are detected by the F100’s five-segment TTL Multi Sensor, then

analyzed for brightness and contrast. Furthermore, when a D- or G-type AF Nikkor lens is attached, 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.

With a Speedlight with Monitor Pre-Flash function or the SB-24, you can cancel the Automatic Balanced Fill-Flash with TTL Multi Sensor to perform Standard TTL Flash. Multi-Sensor Balanced Fill-Flash can also be performed with the SB-24 and other dedicated Speedlights that do not have the Monitor Pre-Flash feature. Select a metering system other than Spot Metering with the F100. (The Flash mode automatically switches to Standard TTL flash with Spot Metering.)

Center-Weighted Fill-Flash

Center-Weighted Fill-Flash is performed with a TTL AF Speedlight and non-CPU lens. Since Center-Weighted Metering is used instead of Matrix Metering with a non- CPU lens, flash output and ambient light of the main subject and background are roughly balanced. If a highly reflective object is located within the frame or the background is non-reflective, correct exposure may not be obtained. With a Speedlight with Monitor Pre-Flash function or the SB-24, you can cancel the Center- Weighted Fill-Flash to perform Standard TTL Flash.

Standard TTL Flash

With a Speedlight with Monitor Pre-Flash function or the SB-24, Standard TTL Flash can be performed with any type of lens. With other Speedlights, Standard TTL Flash is automatically set when the camera is set to Manual exposure mode. In Standard TTL Flash, automatic flash output level compensation is not available. This means that, even though the main subject is correctly exposed, the background may not be. (Selecting Spot Metering automatically switches the TTL auto flash mode to Standard TTL Flash.)

Accessory Shoe/Sync Terminal/Ready-Light

•Accessory shoe

• An optional Speedlight such as SB-80DX, SB-50DX, SB-30, SB-29s/29, SB-28/	Flash
28DX, SB-27, SB-23 or SB-22s can be attached directly to the accessory shoe

of the F100 without a cord. This accessory shoe is equipped with a safety-lock which prevents accidental drop when a Speedlight with a safety-lock pin (SB-80DX, SB-30, SB-29s/29, SB-28/28DX, SB-27, SB-26, SB-25 or SB-22s) is attached.

•Sync terminal

•To use a Speedlight that requires a sync cord, attach one end of the sync cord to the sync terminal.

When a Speedlight such as SB-80DX, SB-50DX, SB-30, SB-29s/29, SB-28/ 28DX, SB-27, SB-23 or SB-22s is attached to the F100’s accessory shoe and rear-curtain sync is performed, do not attach additional Speedlight via sync terminal.

•Ready-light

•When using a Speedlight such as the SB-80DX, SB-50DX, SB-30, SB-29s/29, SB-28/28DX, SB-27, SB-23 or SB-22s, the ready-light fi lights up 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 (when the Speedlight is set to TTL or non-TTL auto flash mode). Check the focus distance, aperture or flash shooting distance range and shoot again.
