I was thinking of attaching my RS-1 to the QR plate (Manfrotto), but decided not to. The D-ring is not designed to hold the weight of camera + lens + flash, AFAIK. Secondly, the D-ring is designed to help you turn the screw that fastens the QR to the camera. So what happens when you hang your camera by the D-ring and it rotates around? Your QR plate gets loose --> disaster.
Was wondering if I should get a Wimberley lens ring to attach the RS-1 to, and reserve the QR for tripod use. THat would allow me to use a tripod with RS-1 attached. Any comments?
