Set-up Menu 2, Item 7: External Speedlite Control, allows you to control the flash from the camera, or to control all settings from the flash, dependent on the particular Speedlite. These choices include:
• Flash Mode. Choose between Evaluative and Average.
• Shutter Sync. Choose between first curtain or second curtain shutter sync. With first-curtain sync, the flash fires at the beginning of the exposure and the shutter then stays open to record the existing ambient light. With second curtain sync, the ambient light is recorded first and then the flash is fired.
