Using Built-in and Optional Speedlights Taking Photographs-Flash Photography Using an Optional Speedlight Optional Speedlights with D-TTL Flash Control SB-series 80DX, 50DX, and 28DX Speedlights support D-TTL flash control when mounted on the camera accessory shoe ( 104). D-TTL flash control is not available with other optional Speedlights ( 106). The type of flash control available with SB-series 80DX, 50DX, and 28DX Speedlights depends on the type of lens attached: Lens Type G or D CPU lens Other CPU lens All types Flash control 3D Multi-Sensor Balanced Fill-Flash for Digital SLR Multi-Sensor Balanced Fill-Flash for Digital SLR Standard TTL Flash for Digital SLR The SB-80DX and SB-50DX Speedlights The SB-80DX and SB-50DX support D-TTL flash control ( 95). When used in combination with a type G or D lens, they support 3D multi sensor balanced fill flash for digital SLR for natural, balanced light, even when the scene contains highly reflective objects or the background is very far from the camera. Both models offer AF-assist illumination, and are equipped with auto power zoom that adjusts the flash angle according to the focal length of the lens. Nikon SB-80DX Speedlight The SB-80DX is a high-performance Speedlight with a guide number of 53/ 174 (m/ft, manual mode, 35-mm zoom-head position, ISO 200, 20 °C/68 °F; GN at ISO 100 is 38/125). It can be powered by four LR6 (AA) alkaline batteries or by SD-7, SD-8A, and SK-6 power sources (all available separately). For bounce-flash or close-up photography, the flash head can be rotated through 90 ° up, 7 ° down, 180 ° left, and 90 ° right. Light from the flash can be diffused for wide-angle photography by using the SB-80DX in combination with a wide panel or bounce adapter, producing soft lighting that balances the foreground subject with the background in close-ups and bounce-flash photography. The SB-80DX is equipped with an illuminator to assist in adjusting settings in the dark. Custom settings allow you to fine-tune all aspects of flash operation. 103
