Olympus M. In-Focus Trigger Cord
This cord automatically triggers the Motor Drive or Winder when the subject is in focus. It can either be used with (combination 1) the OM-30 (OM-F) and any manual focus Zuiko lens, or with (combination 2) any OM body and the 35-70mm/F4 Auto Focus zoom lens.
The main body of the M.In-Focus Trigger cord (the part with the red Standby Button) is inserted in the Remote Control Jack of the Motor Drive or Winder.
The other side of the Cord goes either (combination 1) into the M.In-Focus Control Jack on the left hand side of the OM-30 body or (combination 2) into the M.In-Focus Control Jack of the 35-70mm/F4 Auto Focus zoom lens. If the OM-30 is used with the 35-70mm/F4 Auto Focus zoom lens, either of these Jacks can be used..
The M.In-Focus Trigger Cord is activated by pressing the red Standby Button. When the Standby Button is pressed and rotated clockwise, the standby (ready) state is locked. To unlock, rotate it anti-clockwise untill the white buttons are in opposite position, and release.
