The Phottix Raja series of soft boxes open like an umbrella and are ready to use almost immediately. It easily pops open and mounts to any compatible light. The Phottix Raja Strip Softbox 30x140 (12"x55") is a narrow strip modifier, perfect for full, 3/4, or active subject poses. It can easily be rotated to match the angle of the body of a subject. Some photographers will also use this with the included grid to selectively light only a portion of a subject and the frame. Like all Raja Softboxes, the Strip Softbox 30x140 comes with the S-Mount, inner baffle, outer diffuser, fabric grid, and a carrying case.
