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.
