Learn how to set up a quick folding softbox in minutes. Step-by-step guide for studio lighting, including tips on unfolding, mounting, and collapsing.
Quick Answer
Set up a quick folding softbox by unfolding the frame, attaching the Bowens mount, and locking it onto your studio light. The Phottix Rex Pro series collapses to 50mm for easy storage.
Why a Quick Folding Softbox Saves Time in Studio
Traditional softboxes require assembling rods and threading them through fabric, which can take several minutes. A quick folding softbox uses pre-attached fiberglass ribs that pop into shape in one step, cutting setup time to under 30 seconds. This is especially useful during fast-paced shoots or when you need to move lights between locations.
The Phottix Rex Pro series uses either 4 or 16 fiberglass ribs depending on the size, with a silver-lined interior for efficient light reflection. The trade-off is that the frame is not user-replaceable, so handle the softbox carefully to avoid rib damage.
Understanding the Bowens Mount Connection
Most studio lights use a Bowens mount, which is a standard bayonet-style locking ring. The Phottix Rex Pro softbox features a quick-release Bowens mount design that attaches directly to compatible strobes or continuous lights. Ensure your light has a Bowens mount before purchasing; if it uses a different system, you may need an adapter.
The mount has a release button that must be pressed to remove the softbox. Always check that the mount is fully locked before letting go to prevent the softbox from falling.
Step-by-Step Setup Guide
- Unfold the Softbox Frame: Hold the softbox by the speed ring (mount) and gently push the center of the fabric outward. The fiberglass ribs will automatically spring into shape, forming the softbox profile. Do not force the ribs; let them expand naturally. Common mistake: Pulling on the fabric instead of pushing from the center can misalign the ribs.
- Attach the Bowens Mount to Your Light: Align the three tabs on the softbox mount with the slots on your studio light’s Bowens ring. Push the softbox onto the light until it clicks, then rotate the locking ring clockwise to secure it. Listen for the click and give a gentle tug to confirm it is locked. Checkpoint: If the softbox wobbles, the mount is not fully locked. Rotate the ring until it is snug.
- Adjust the Softbox Position: Once mounted, tilt or swivel the softbox to aim the light where you need it. Most studio light stands have a tilt lock – tighten it after positioning. For a softer light, move the softbox closer to the subject; for harder shadows, move it further away. Common mistake: Forgetting to tighten the tilt lock can cause the softbox to droop during the shoot.
- Collapse the Softbox for Storage: Press the “One-Push Release” button on the mount while gently pushing the softbox toward the mount. The ribs will fold inward, and the softbox will flatten to about 50mm thick. Store it in the included slim carrying bag to protect the ribs. Checkpoint: Never fold the softbox by bending the ribs manually – always use the release button to avoid breaking the fiberglass.
