Optional Tray with Release Handle, required to attach optional SubStrobes, allows easy attachment and removal of SubStrobe mounting arms at the touch of a button. Placement of the rubber handle does not interfere with housing opening and closing.

The sensor placement on the camera and addition of diffuser precludes use of the TTL Slave Sensor. The EV Manual Controller is suggested. It provides 10 power settings with all DS model digital SubStrobes.
