The EZ-Pro series of soft boxes are designed for ease of use. They are great for travelling and location photographers requiring a quick and easy setup. The soft box features a collapsible umbrella like structure with heavy duty rod support. Almost instant setup, open the soft box like an umbrella, snap the speed ring into place on the light and done! The baffle and outer diffuser can stay on the light while in storage so it's always ready to use. Tear down is a breeze too; just remove the soft box from the light and release the umbrella-like mechanism inside (if a grid is attached, remove that first), the soft box collapses right down. The diffusion panels can be kept in place during take down, they do not need to be removed before collapsing the soft box. The EZ-Pro series also come with its own carrying bag. The optional eggcrate grid contains the light to a more tubular pattern for more of a spotlight effect without light spill (sold separately).
