The Phottix Essentials Reflective Softbox Studio Umbrella 40" is a fast and convenient way to achieve soft and diffused lighting. With its umbrella design, it can be easily set up and mounted to most umbrella holders. The umbrella reflects light from your flash back through a diffusion panel, creating a soft and gentle light quality. The drawstring closure helps to secure the softbox around your flash head or speedlight, preventing any unwanted light spill.
