The Phottix Extra Large Octa Easy-Up HD Umbrella Softbox with Grid 120cm is made with internal white fiberglass spokes for high durability. Perfect for on-location shooting. It folds down like a regular umbrella but expands straight into a square softbox for instant use, saving time over traditional softboxes which require rods and speed rings for assembly. The recessed-front diffuser allows for more precise positioning and feathering of light. Included is a removable grid to better control light spill in situations when accuracy is essential. A flash or studio light mounts backwards inside the softbox. Shooting towards the rear creates an even light which reduces any photo spoiling hot spots. The Phottix Extra Large Octa Easy-Up HD Umbrella Softbox with grid 120cm can be collapsed and stored in seconds, easily transported or stored. Items Include: 1 - Phottix Easy Up HD Umbrella Extra Large Octa Softbox (120cm/47'') 1 - Grid 1 - Diffuser
