1 Available flash modes
The TTL and M (manual) flash modes are available with the SU-800 and
SB-R200. Use of TTL mode is recommended for normal flash
photography.
• Be sure to read the instruction manual of the camera in use.
TTL auto flash mode
In this mode, the flash illumination that is reflected back from the subject is
detected by the camera’s TTL auto flash sensor and the camera automatically
controls the flash output level to give the correct exposure.
i-TTL mode is available with CLS-compatible cameras, D-TTL mode is available with
digital SLR cameras not compatible with CLS, and TTL mode is available with cameras
compatible with TTL auto flash mode. The following flash operations are available.
TTL-BL flash (Automatic Balanced Fill-Flash)
Based on exposure measurements obtained by a Matrix metering system, the
flash output level is automatically adjusted for a well-balanced exposure of the
main subject and background.
TTL flash
The main subject is correctly exposed regardless of background brightness.
This is useful when you want to highlight the main subject or make exposure
compensation.
About the flash shooting distance range in the TTL auto flash mode
When the SB-R200 is used as a remote flash unit, the flash shooting distance
range is 0.6m to 28m (2 to 92 ft.) and varies depending on ISO sensitivity and
lens aperture in use.
