I've never owned soft boxes or octo boxes yet and don't know much about speed rings. Is the part that the soft box rods connect to all the same and only the part that attaches to the strobe unique to each strobe? I just ordered the D-Lite 2 kit and was thinking of buying the Photoflex speed ring for Elinchrom mount. But I want to know if the Amvona soft boxes and octo boxes would be able to attach to the speed ring. Hope I made sense.
