For triggering remote cameras, a longer contact time allows for continuous repeatable
motor drive triggering (example: 5 frame bursts every trigger). It also allows for
controlled bulb exposure.
• Example of Burst Shooting: If a remote camera is capable of firing 3 frames
per second in continuous motor drive, then a contact time of 1 second will
always result in this remote camera triggering for 3 exposures
• Example of Bulb / Shutter Held Open: Set the contact time for the desired
bulb exposure time and set the camera to bulb or B mode. When triggered the
shutter will remain open for the contact time
For triggering a remote flash contact time can act as a flash recycle lockout.
• Example of Flash Recycle Lockout: To guarantee that a flash cannot be
triggered faster then its recycle time, set the contact time to be just longer than
the recycle time
L This method of flash recycle lockout does not work with all flash systems as some
will not recycle while the sync contact is held. See Recycle Lockout in the
Applications of Advanced Functions section, Page 42, for another recycle lockout
method.
L If you are using Intervalometer or Multipop modes, read these sections, Page 36
and Page 37, for information on these modes and how they interact with Contact Time.
