MagBox 24" Octa FocusDiffuser

Grid + Lens + Diffuser
MagMod Satisfaction Guarantee

MagMod is backed up with a no-nonsense 30 day satisfaction guarantee, and MagMod products are also covered by a limited warranty.


The FocusDiffuser offers a whole new way to modify your softbox. With magnets allowing for easy setup, the FocusDiffuser lets you control light like a grid, but also focus it like a lens—all while keeping your light super soft. Your old school fabric grid can't multi-task like that! You'll love how simple it is to limit spill and increase the effective output of your softbox by 2 stops (vs. MagBox with Fabric Diffuser).

Fabric Diffuser

You Have the Power

Thanks to its efficient, obstruction-free design, the MagBox is the brightest softbox on the market. The MagBox with FocusDiffuser is 2 stops brighter than the MagBox with Fabric Diffuser. When compared to a traditional gridded softbox, the MagBox with FocusDiffuser is dramatically brighter—an average of 3 stops more effective light output. Now you can shoot at a lower flash power and enjoy faster recycle times and longer battery life.

Awesome light!

I loved the wuality and directional light using the focus diffuser. It may stay on the MagBox permanently.

Glad to have it back!

I’ve always loved this item. I lost it at the end of 2019 and finally was able to replace it by purchasing a new one. Great product.

Awesome customer service

I am thankful for MagMod customer service when I had issue with my focus diffuser. They resolved my issue right away.

One Big, Happy Family

MagBox products integrate seamlessly with the rest of your MagMod gear. So go ahead and try things you've never tried before: stack up rigid gels, stack multiple modifiers or switch deftly back and forth between large and small light sources. Nailing the perfect image—and knowing you can do it quickly and easily without fail—unlocks a whole new world of creative confidence.
