The Manfrotto Brolly Grip Kit with 20" Umbrella is an effective diffusion solution for what Lastolite would call the "solo strobist." For the dexterous that means that you can handle your autofocus DSLR with one hand while effectively using your arm as a light stand for your umbrella. Lastolite makes it easy with the inclusion of a grip handle which alternatively mounts on a 5/8 (16 mm) stand stud as well as a 20" translucent umbrella. Just add your on-camera flash and shoot.
