C.Fn-15-1:By using a slow sync speed, you can create a light trail following a moving subject. The flash fires right before the shutter closes.

This Custom Function can be used to obtain 2nd-curtain sync effects even with EX-series Speedlites which do not have this capability. If an EX-series Speedlite having this capability is set for 2nd-curtain sync, it will override the camera’s setting.
