The Lastolite TriFlash by Joe McNally is a further
refinement of the original TriFlash. In use, sometimes the positioning
of the IR sensor can become problematic. This Joe McNally version
features unique rotating shoes for all 3 flashes to ensure that the
sensor on each flash "sees" the on-camera master flash. The mount also
features an umbrella receptacle and a 5/8" (16 mm) stand mount.
