C.Fn-05 Shutter curtain sync with built-in flash and EX-series Speedlite

0 : 1st-curtain sync

1 : 2nd-curtain sync

With second-curtain sync and a slow shutter speed, you can create a light trail following a moving subject. The flash fires right before the shutter closes. Second-curtain sync can be set even with EOS-dedicated Speedlites which cannot switch the shutter curtain synchronization. The Speedlite with a shutter curtain synchronization setting will override the camera’s setting.

∗When you press the shutter button completely, a preflash will be fired for flash exposure control.

C.Fn-06 Flash sync speed in Av mode

0 : Auto

1 : 1/125 sec. (fixed)

When you use flash in the aperture-priority mode (Av), the flash sync speed will be fixed at 1/125 sec. This prevents the camera from setting a slow sync speed in low-light conditions.
