great. is it exactly the one i've posted? because there are 2 for nauticam 72mm flat port and m77 flat ports And there is a cheaper one for m67 ports, not especially for nauticam.
sorry, but i live on maledives and then its hard to change gear, if its not fitting
think u have this one? -> https://www.unterwas...6o73d0ru6gkl5v2
Not really, my had art nr D&DNA-36163 - D&D NAUTICAM M67 Flip Diopter Holder for Macro Port 65 , I do not see this any more.
It is similar to link , I guest that port number does not matter as long as it has the same thread M67.
I have removed one piece, originally it is designed for two lenses. I used with port 65 and thread M67.
