The Flash Multiplier Adapter for Small 1.5 x 3" Flashes from Vello has a Fresnel lens that allows this flash head's output to be increased by up to three stops for long throw work such as nature photography. Alternatively, you can remove the Fresnel and replace it with the included diffuser to use the Flash Multiplier as a softbox.
