1Available 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.
