Already have a MagShoe?

Due to the additional weight and size of the MagBox Pro 42 and MagBox Pro 36 you must use the stronger MagShoe 2 instead of the original MagShoe.

Using the MagBox Pro with the original MagShoe could damage the MagShoe!

Watch this video for more information on this change.

The MagBox Pro Grid magnetizes to the MagBox instantly and effortlessly, saving photographers from the annoying and clumsy experience of other velcro-style softboxes.

The instant snap-on sound when the MagBox Pro Grid attaches feels automatic, secure, and is more satisfying than a perfect knuckle crack! 

Integrated Zip-On Diffuser

An industry first, the integrated zip-on diffuser on the MagBox Pro is something you kind of have to experience for yourself to truly appreciate. As simple as it sounds, this sweet zip-on zip-off action makes your MagBox totally easy and frustration-free.

Want to change up your look and go diffusion free? The zip-off diffuser tucks neatly away into an integrated inside pocket in seconds so you'll never have to worry about losing your diffuser or figuring out where to store it-it's always ready to go.

You Gellin?

Before the MagBox, adding color to a large softbox was next to impossible. The MagBox's patent-pending design ingeniously adapts gels to larger softbox modifiers for the first time ever, which made it the first gel-able softbox.

Simply pop one of the rigid MagBox Gels into the frame and just like that you've got a colorful, soft light. 

Easy Side Access Zipper

A zipper built right into the side of the MagBox makes it easier for you to swap out the colored gels during your shoot without removing the diffuser or fabric grid.

Durable Fabric Exterior

The new MagBox PRO delivers a new lighter-weight fabric shell made of rip-stop fabric. It not only looks good, but is super durable.

Strobe or Speedlites

The MagBox is the most versatile softbox ever, making it one super smart investment. Use it with 1 or 2 Speedlights—any flash that has our patented MagGrip installed will work.

The MagBox is equally happy being mounted to large studio strobes... and LED video lights using one of our optional MagBox Speeding Adapters to mount a Profoto, Bowens, Elinchrom or Paul C. Buff strobe.

MagBox Large Case

A professional softbox isn't complete without a professional-grade storage solution.

The MagBox Pro Case is now wrapped in a rigid outer shell that not only makes it easier to store your MagBox Pro when not in use, but keeps it safe from negligent assistants or baggage handlers.

Do you love soft light??

I loved (and still LOVE) everything about the MagBox 24" but when the MagBox Pro 42 was released, I was over the moon! I'm a sucker for large soft light and this modifier fits the bill. It breaks down and sets up in seconds and the new zipper design on the front diffusion makes this process so much easier. You never have to worry about the diffusion coming off and you possibly losing it. They've also incorporated a a nice pouch built into the inside of the MagBox which allows for storage of the front diffusion when it's not in use. Super convenient! I'm also a huge fan of the magnet system for attaching Grids, which is way better and less noisy than using velcro usually found with other brands. All in all, this is the perfect addition to the kit and a great compliment to the full MagMod product lineup.

Love the lighting quality

I have to make this work because I loved the light quality but unfortunately, its very heavy, the first day I used it with my strobe it fell off when I tried to adjust the light stand and it broke the $100 bulb. Very sad.
