•Shutter sync. (1st curtain*/2nd curtain/High-speed)

-1st curtain: This is the normal flash shooting mode in which the flash fires at the timing when the shutter is fully open.

-2nd curtain: The flash fires right before the shutter closes.

-High-speed: This mode enables flash shooting at all shutter speeds. This is effective when you want to use aperture priority for fill-flash portraits.

•Flash exp. comp

You can adjust the flash output level in the same way as normal exposure compensation.

•E-TTL II (Evaluative*/Average)

-Evaluative: Fully automatic flash shooting can be performed, from dark scenes to fill-flash shooting.

-Average: Metering is averaged for the entire scene.
