The new line of RFi speedrings adaptors makes the RFi softboxes compatible with well over 20 different flash brands, ranging all the way from speedlights to high-end studio strobes. Even if you own flashes from many different manufacturers, you now only need one brand of softboxes!
The speedring adaptors are designed so that the RFi softboxes can be rotated 360°, allowing the photographer to adjust and shape the light on the fly. The color codes make the softboxes easy to assemble and disassemble, and all speedring adaptors are robust and painted with heat resistant lacquer.
