I have been searching for a ring flash unit for my camera and came across this contraption online. It is the Ray Flash Ring. Not really a ring flash but an adapter that is made for Nikon and Canon speedlights to direct the light around the lens. I ordered one for my SB900 and it came today. After taking a few test shots I am very happy with the results. It is kind of a beast to handle, the size is pretty impressive so I don't know how much I will be packing it around in my camera bag, unless I upgrade bags.....again.
