Softbox (40 cm) Aputure Light Dome 40 — compatible with STORM 80c, diameter 40 cm, black

Aputure Light Dome 40 is a compact circular softbox with a 40 cm diameter designed to shape and soften light for photography and videography. Finished in black and supplied as a single unit, it delivers controlled diffusion and a natural falloff that helps reduce harsh shadows while maintaining directional output. The dome’s folding structure enables rapid assembly and quick storage, making it practical for studio use and on-location shoots with the Aputure STORM 80c.

Advantages

The Light Dome 40 provides uniform, soft illumination through its circular diffuser, producing pleasing catchlights and smooth tonal transitions. Its Mini ProLock mount ensures secure, tool-free attachment to compatible fixtures and maintains a stable connection during shoots. Lightweight construction and a foldable design allow fast setup and compact storage, while the black exterior helps control spill and maintain contrast.

How to use

Unfold the Light Dome 40 and extend the frame until it locks into position. Attach the Mini ProLock mount to the corresponding receiver on the STORM 80c and rotate or secure according to the mount’s engagement mechanism. Position the softbox at the desired distance and angle from the subject to adjust softness and falloff. Use the included diffuser to achieve even light distribution; add flags or grids (sold separately) at the front if greater directionality or contrast control is needed.

Usage recommendations

For portrait work, place the Light Dome 40 slightly above eye level and angle it downward to create natural-looking catchlights and soft shadows. For product photography, reduce distance to increase softness while monitoring reflections; use black or neutral flags to control unwanted spill. Store folded to protect the diffuser and maintain frame integrity.
