SB-80DX available flash modes The SB-80DX’s available flash modes vary, depending on the cameras and lenses in use or the camera’s exposure mode.

*1 Monitor Preflashes are fired.
*2 3D Multi-Sensor Balanced Fill-Flash and Multi-Sensor Balanced Fill-Flash are generally referred to as Automatic Balanced Fill-Flash with TTL Multi Sensor (Automatic Balanced Fill-Flash with TTL Multi-Sensor for Digital SLRs in D-TTL auto flash).
*3 The TTL auto flash mode for Nikon Digital SLRs is called the D-TTL auto flash mode.
*4 In the D-TTL auto flash mode, Monitor Preflashes are fired at all times.

TTL/D-TTL auto flash mode The SB-80DX’s TTL/D-TTL auto flash mode varies, depending on the cameras and lenses in use or the camera’s exposure mode and metering system.

iconTTLmatrix.gif 3D Multi-Sensor Balanced Fill-Flash/ iconDTTLmatrix.gif 3D Multi-Sensor Balanced Fill-Flash for Digital SLRs Information obtained by the Monitor Preflashes, exposure control information, and distance information from a D- or G-type lens are integrated to automatically adjust the flash output level to obtain a well-balanced exposure of the main subject and background.

iconTTLmatrix.gif Multi-Sensor Balanced Fill-Flash/ iconDTTLmatrix.gif Multi-Sensor Balanced Fill-Flash for Digital SLRs Information obtained by the Monitor Preflashes and exposure control information is integrated to automatically adjust the flash output level for a well-balanced exposure of the main subject and background.

iconTTLfilin.gif Matrix Balanced Fill-Flash Exposure control information obtained by the camera’s Matrix meter is used to automatically adjust the flash output level for a well-balanced exposure of the main subject and background.

iconTTLfilin.gif Center-Weighted Fill-Flash/Spot Fill-Flash Exposure control information with Center-Weighted or Spot Metering is used to adjust the flash output for a natural Fill-Flash effect.

iconDTTLfillin.gif Center-Weighted Fill-Flash for Digital SLRs Exposure control information with Center-Weighted Metering is used to adjust the flash output for a natural Fill-Flash effect.

iconTTL.gif Standard TTL Flash/ iconTTL.gif Standard TTL Flash for Digital SLRs The main subject is correctly exposed regardless of the background brightness. Useful when you want to highlight the main subject.

Balancing the exposure for the main subject and background The degree of exposure balance for the main subject and the background varies as the type of TTL auto flash mode changes. The most well-balanced TTL auto flash exposure is obtained when using 3D Multi-Sensor Balanced Fill-Flash and decreases through Multi-Sensor Balanced Fill-Flash, Matrix Balanced Fill-Flash, Center-Weighted/Spot Fill-Flash, down to Standard TTL Flash in that order. The above description is applicable to the D-TTL auto flash mode.

Monitor Preflashes Monitor Preflashes are available in Automatic Balanced Fill-Flash with TTL Multi-Sensor and all flash modes in D-TTL auto flash to determine the condition of the subject. After you press the shutter release button and just before the shutter opens, the SB-80DX fires a series of imperceptible preflashes that are detected by the camera’s TTL Multi-Sensor and analyzed for brightness and contrast. (Please note that Monitor Preflashes are fired instantaneously and cannot be differentiated from the main flash.)

Usable Nikon SLR cameras compatible with the TTL/D-TTL The available types of TTL/D-TTL auto flash vary, depending on the camera/lens/exposure mode/metering system being used: -

Flash shooting distance range in the 1/300 TTL High-Speed Flash sync mode (Nikon F6/F5 & other applicable Nikon SLRs only) The farthest flash shooting distance cannot be read on the SB-80DX’s LCD panel. In this case, use the guide number table and equation for calculating this distance, according to each zoom-head position.

D (farthest flash shooting distance) = Guide number ÷ f/stop (aperture)

tableL.gif

*1 With the Nikon Diffusion Dome attached and the wide-flash adapter in place
*2 With the Nikon Diffusion Dome attached
*3 With the wide-flash adapter in place For example, when shooting with an ISO sensitivity of 100, at a 35mm zoom-head position and an aperture of f/5.6:
D = 14 ÷ 5.6 (f/stop) = 2.5 (in meters) (farthest flash shooting distance)
D = 46 ÷ 5.6 (f/stop) = 8.2 (in feet) (farthest flash shooting distance)

Non-TTL auto flash "A" mode

The SB-80DX’s built-in sensor measures the flash illumination reflected back from the subject, automatically controlling the SB-80DX’s light output to give the correct exposure. This allows you to make exposure compensation easily by varying the aperture set on the camera or lens. To Operate: 1 Set the camera’s exposure mode to Aperture-Priority Auto (A) or Manual (M). 2 Press the MODE button until “A” appears on the LCD panel. 3 Press the + or - button to change the aperture, bringing the subject within the flash shooting distance range. 4 Set the aperture that appears on the SB-80DX’s LCD panel on the lens or camera. 5 Set the camera to its highest flash sync shutter speed. 6 Compose the picture, make sure the ready-light is on, then shoot. When the flash has fired at its maximum output and underexposure may have occurred, the ready-light on the SB-80DX blinks for approx. 3 sec. To compensate, use a wider aperture or move closer to the subject and re-shoot.

Setting the aperture in the Non-TTL auto flash "A" mode Set the aperture within the available range as shown in the table below:

Usable flash shooting distance ranges in Non-TTL auto flash and Auto Aperture flash mode

*1 With the Nikon Diffusion Dome attached and the wide-flash adapter in place *2 With the Nikon Diffusion Dome attached *3 With the wide-flash adapter in place

For example, for an ISO sensitivity of 100, with the zoom-head position adjusted to 35mm, and the subject at a distance of 5m (16.4 ft.), selecting apertures from f/2 to f/5.6 from the table will give the correct exposure. To set the aperture on Zoom-Nikkor lenses having variable maximum apertures, refer to “The flash shooting distance range with zoom lenses having a variable aperture”

Auto Aperture "AA" AAmode.gif flash mode

In addition to Non-TTL auto flash, the SB-80DX’s built-in sensor correctly controls the flash output in combination with data automatically transmitted from the camera and lens to the SB-80DX, including the ISO sensitivity value, aperture, focal length, and exposure compensation value. The Non-TTL auto flash mode is automatically set when a non-CPU lens is mounted on Digital SLRs.

To operate: 1 Set the camera’s exposure mode to Programmed Auto (P) or Aperture-Priority Auto (A). 2 Lock the CPU lens aperture at its minimum (Not necessary with a G-type lens). 3 Press the MODE button to select the AAmode.gif (Auto Aperture flash) mode. 4 While looking at the flash shooting distance range on the SB-80DX’s LCD panel, set the aperture on the camera. 5 Compose the picture, confirm that the ready-light is on, then shoot. When the flash has fired at its maximum output and underexposure may have occurred, the ready-light on the SB-80DX blinks for approx. 3 sec. To compensate, use a wider aperture or move closer to the subject and re-shoot.

Setting the aperture in Auto Aperture AAmode.gif flash mode Set the aperture on the camera or lens within the available range as shown in
the table below: -

Usable flash shooting distance ranges in the Non-TTL auto flash and Auto Aperture flash mode

*1 With the Nikon Diffusion Dome attached and the wide-flash adapter in place *2 With the Nikon Diffusion Dome attached *3 With the wide-flash adapter in place

For example, for an ISO sensitivity of 100, with the zoom-head position adjusted to 35mm, and subject at a distance of 5m (16.4 ft.), selecting an aperture of f/2 to f/5.6 from the table gives the correct exposure.

Manual iconM.gif Flash Mode In this mode, the Nikon SB-80DX (applicable to all Nikon speedlights) flash always fires at a specified output. The SB-80DX features three types of manual modes.

header3.gif Determining the aperture and flash output level in the Manual mode In the Manual mode, use the guide number table and the following equation to calculate the aperture, flash output level, and shooting distance to obtain the correct exposure. The guide number (GN at ISO 100; m/ft) indicates the amount of light generated by the flash. The larger the number, the greater the flash output.

Guide number (ISO 100, m/ft)
tableO.gif
Note: You can calculate the correct aperture by using the guide number table and the shooting distance. Then set the same aperture manually on the lens. In this case, set the camera’s exposure mode to Aperture-Priority Auto (A) or Manual (M). If the camera’s exposure mode is set to other than Aperture-Priority (A) or Manual (M) mode, the shutter may not be released, depending on the cameras in use. In the Manual mode, no warning ready-light blinks to indicate that the light may have been insufficient for correct exposure after shooting.

ISO sensitivity factors For sensitivity other than ISO 100, multiply the guide number at an ISO sensitivity of 100 by the factors shown in the guide number table.

Manual flash operation In Manual flash photography, you select the aperture and flash output level. In this way, you can control the exposure and flash shooting distance when shooting subjects where the correct exposure is difficult to obtain in the TTL or Non-TTL auto flash mode. In Manual flash operation, the flash output level can be set from M1/1 to M1/128 to match your creative preferences.

Setting the flash output level The flash output level changes every time you press the for button as shown below.

 

When you press the iconplus.gif button:

 

When you press the iconminus.gif button:


The numbers in parentheses represent the adjustable flash output level in ±1/3 steps except between 1/1 and 1/2. Therefore, 1/32 (-0.3) and 1/64 (+0.7) represent the same flash output level. indicates FP High-Speed Flash sync. This indicator appears only when the SB-80DX is used in combination with cameras compatible with FP High-Speed Flash sync. To extend the flash shooting distance, choose a flash output level close to M1/1.
