The Lastolite TriFlash Sync Bracket is the same bracket as the TriFlash Shoe Lock bracket but with important enhancements. Like the Shoe Lock, the TriFlash Sync allows you to mount up to three portable flashes on a single bracket, which can then be mounted on a standard 5/8" (15.87 mm) stud. An umbrella socket allows the use of a reflective or shoot-through umbrella.
Additionally the TriFlash Sync includes a built in optical slave which can be set to recognize 1, 2 or 3 pre-flashes or none at all. This is an important attribute for those using various red-eye reduction or TTL systems. The bracket also includes a 3.5 - 3.5 (mini - mini) and 3.5 mm - PC male sync cords for use of other brands of triggering devices. A cold shoe is provided to accommodate receivers with a male shoe mount. However, the TriFlash brackets are not compatible with Sony flash units.
