I just got a Norman ML400 and the Norman softbox with the proper Norman adaptor ring. Has anyone else used this combination? You simply put the ring inside the softbox and mount the softbox/ring combo onto the flash housing. Correct? Mine has a large amount of play - is this normal? The softbox doesn't fall off the flash but am I missing something? The softbox didn't come with any instructions, although it seemed straightforward and the pieces would only fit one way. I've previously always used umbrellas which mount solid to the flash housing. I ordered this from Adorama which is closed on Saturdays so they're no help. Thus any help is appreciated.
