The Lastolite Brolly Grip Handle 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 Brolly Grip Handle which alternatively mounts on a 5/8 (16 mm) stand stud and holds optional umbrellas up to 20".
