6 Repeating (RPT) flash operation
What is Repeating flash operation
In Repeating flash operation, the Speedlight fires repeatedly during a single
exposure, creating stroboscopic multiple-exposure effects. This operation is
useful when shooting fast-moving subjects. When using cameras compatible
with CLS, the SU-800 controls the flash output of the remote flash units (such as
the SB-800), which are divided into three groups (A, B, and C), independently for
each group.
• Be sure to read the instruction manual of the Speedlight in use.

Notes on Repeating flash operation
• The SB-R200 cannot be used.
• Setting the flash units in group A or B to fire or cancel is not possible using the [A B]
select button. Use the flash mode setting.
• Be sure to use fresh batteries and allow enough time for the flash to recycle between each
repeating flash session.
• Also, because of the slower shutter speeds, use of a tripod is recommended to prevent
camera/flash shake.
