Detachable adapter accommodates a diffuser and various apertures for the A10157 background reflector. The frame holder slides easily into the reflector and locks with a simple turn of a lever. Comes with three aperture frames: a brushed aluminum frame which can be folded to remove diffuser and replace with gels; and two additional frames, one with a 2" opening and the other with a 3" opening, either of which can be fully rotated on the PowerLight. All three frames and diffusers can be used at once.
