Pros & Cons
👍 Pros
- Color-coded assembly eliminates fumbling with rod placement during fast-paced location setups
- Opens up the full Profoto RFi softbox ecosystem for Photogenic strobe owners
- Solid mounting connection keeps the softbox firmly seated even when tilted at steep angles
- Compact 7.1-inch profile doesn't add significant depth between strobe and modifier
👎 Cons
- At 1.3 pounds, it adds noticeable weight to the front of your light stand when combined with a large softbox
- Only works with Photogenic-mount strobes—won't cross-fit to Bowens or other proprietary mounts
- Premium Profoto pricing compared to generic speedring adapters that serve the same basic function
- Does not include a softbox, so you're buying the adapter as a separate investment
Frequently Asked Questions
Which softboxes does this speedring work with?
It's compatible with the entire Profoto RFi softbox line—square, rectangular, and octagonal. The color-coded rod system means you use the same adapter regardless of softbox shape.
Will this fit my specific Photogenic strobe model?
The adapter is designed for Photogenic flash heads. Confirm your strobe's mounting ring style matches the Photogenic standard before purchasing, as some older or specialized heads may differ.
How long does assembly take compared to other speedring systems?
Profoto's color-coded rod-to-hole system cuts setup to under a minute once you've done it a couple of times. Match each colored rod to its corresponding hole and lock down—no guessing which rod goes where.
Can I leave the speedring attached to the softbox between shoots?
Yes, many photographers leave the speedring mounted to their most-used softbox to speed up setup on location. The 1.3-pound weight adds minimal bulk for transport.
