Profoto 100503 RFi Speedring Adapter for Elinchrom

If you've invested in Profoto's RFi softbox line for its color-coded simplicity and wide modifier selection, the 100503 Speedring Adapter removes the brand barrier between those modifiers and your Elinchrom strobes. For photographers who rent or own across both ecosystems — or who are transitioning studios from one brand to another — this adapter means your existing RFi octas and strip boxes don't sit idle when an Elinchrom head is on the stand. The result is soft, even light with the quality and character you'd expect from RFi diffusion, regardless of which strobe is driving it.

Build quality is consistent with Profoto's accessory line — the adapter is robust and maintains a secure fit at the Elinchrom bayonet mount through repeated setups and takedowns. The color-coded rod system, a hallmark of the RFi softbox design, works exactly as intended: match the color, push, lock. On a busy portrait session or editorial shoot where you're swapping between modifiers, that system pays for itself in time and frustration saved. The black finish is neutral on set and doesn't introduce any reflective artifacts into the light path.
