Overview

The Aputure Light Dome III is the third generation of Aputure's flagship circular softbox, redesigned from the ground up with a quick-folding mechanism that fundamentally changes how fast you can get soft, professional light on set. Where previous versions and most competitors require threading individual rods into a speed ring, the Light Dome III snaps into its full 35.1-inch octagonal parabolic shape in seconds. This makes it ideal for productions where setup time matters — from run-and-gun documentary work to multi-setup commercial shoots where every minute counts.

Beyond the speed, the Light Dome III delivers the light quality professionals expect. The included 1-stop and 2-stop diffusion cloths let you dial in the exact level of softness your scene requires, while the 40° honeycomb grid adds directional control for more dramatic, contrasty lighting when needed. The Bowens mount ensures broad compatibility across Aputure's lighting ecosystem, from compact amaran fixtures to the powerful 600-series. When the shoot wraps, the softbox folds flat rather than rolling into a bulky cylinder, fitting easily into its included carry bag for streamlined transport between locations.
