Ideal for portrait, product, fashion photography, and more, the GVM Quick Release Portable Softbox measures and features integrated locking rods that quickly lift and snap into place so you're ready to shoot in a fraction of the time it takes to set up a conventional softbox. While the 16-sided shape of the softbox imparts a wraparound light quality, its depth gives it a somewhat sharp falloff that makes feathering and directional control easy. For further directional control, an optional fabric grid is included to narrow the beam and minimize light spill. Other handy features include a silver interior to maximize output for a dramatic and punchy light, and removable front and inner diffusers so you can regulate the softness and contrast. The softbox comes with a bowens-type speed ring. Light Compatibility: Built-In Speed Ring with Bowens S Mount Quick Open Type: Click/Locking Type Dimensions: ø: 23.6 x H: 17.8" / ø: 59.9 x H: 45.2 cm (Open)
