The Movo Honeycomb Grid for Portable Flashes attaches to your portable flash and dramatically narrows the beam of light thats put out by your shoe-mount or handle-mount flash. The effect is a small circle of light, with the size depending on flash-to-subject distance. The grid attaches to your flash with the included touch-tab fasteners.
There are three versions of the Movo Honeycomb. The SG18 (1/8") which will produce the narrowest beam of light, the SG16 (1/6") which is produces a beam a few degrees wider, and the SG14 (1/4") which will produce the widest beam of the three.
