Calumet's Umbrella Adapter with Hot Shoe has been designed to hold any shoe-mounted speedlight. It also features a locking mechanism that allows the use of an umbrella. This unit will fit on nearly any light stand with its 5/8"" female mount and a reversible 3/8"", and 1/4""-20 threaded, female mount insert. Furthermore, the bracket's swivel joint allows you to tilt the head and umbrella up to 180°. This adapter is particular useful if you are travelling a lot and still need the use of flash photography. By using this on your stands, you won't need to lug around heavy lighting gear - Just use your speedlights!
