A Subal 66mm extension ring in great condition. Suggest changing the o-ring. I might have a new one I can include. Have to look.
This ring has an inside ring that makes the opening smaller. That is the part that screws to the housing. See picture.
The inner dimension of the ring is approx. 94mm and at this point it is approx. 84mm. The diameter of your lens would
have to fit through the smaller dimension.
$45 plus shipping.
