Shutter sync.
Normally, set to [1st curtain] so that the flash fires immediately after shooting starts.
Set to [2nd curtain] and use low shutter speeds for natural-looking shots of subject motion
trails, such as car headlights.
Caution
When shooting with [2nd curtain], set a shutter speed of 1/60 sec. or slower. For
shutter speeds exceeding 1/60 sec., first-curtain synchronization is used
automatically even if [2nd curtain] is set.
