Pros & Cons
👍 Pros
- The 7-foot diameter produces a very large, wraparound light source that creates soft shadows and flattering portraits
- The removable black cover allows switching between reflective bounce and shoot-through diffusion without buying a second modifier
- Fiberglass ribs flex rather than snap, improving durability during transport and in windy outdoor conditions
- The doubled steel shaft resists bending under the weight and wind load of the large canopy
- At 2.5 pounds, it is relatively lightweight for a 7-foot modifier and includes a storage case for portability
👎 Cons
- The 7-foot size can be difficult to manage in small studios or tight shooting spaces
- The large canopy catches wind easily outdoors, requiring sandbags or weighted stands for stability
- A single speedlite may not provide enough power to fill the full parabolic surface evenly
- The umbrella requires a bracket or mount with a 7mm shaft opening, which not all budget brackets accommodate
- Collapsing and repacking a 16-rib umbrella of this size takes more time than smaller modifiers
Frequently Asked Questions
Can this umbrella be used as both shoot-through and reflective?
Yes. With the black cover removed, the white interior works as a shoot-through diffuser. With the black cover attached, it becomes a reflective bounce umbrella, giving you two lighting styles in one modifier.
What size light stand bracket does the 7mm shaft fit?
The 7mm shaft tip fits standard umbrella brackets and most strobe/speedlight umbrella mounts. Verify your bracket accepts a 7mm shaft before purchasing.
How durable are the fiberglass ribs compared to metal ribs?
Fiberglass ribs are more flexible and resistant to bending or snapping than traditional metal ribs, making this umbrella better suited for transport and outdoor use where wind is a concern.
Is this umbrella suitable for speedlites or only studio strobes?
It works with speedlites, studio strobes, continuous lights, and even as a natural light diffuser. However, a single speedlite may not fill the full 7-foot canopy evenly — a more powerful strobe or multiple speedlites will produce better results.
Does it come with a carrying case?
Yes, a travel and storage case is included for transport and protection.
