The AS-045 Quick Release Octagonal Softbox with Grid from Ulanzi is a 17.7" softbox designed to set up and collapse quickly. The softbox's front diffusion fabric and inner baffle soften the point-source light while lowering the exposure by 2.1 stops. The softbox delivers a round-shaped beam with soft edges well-suited to portrait and fashion photography. A fabric grid is also included to help tighten the beam angle and control unwanted light.
