Yesterday a friend and I tried to swap the pl for the nikon mount. We both have worked on cameras extensively. We were very careful but wound up stripping out 2 screws so we cant remove the PL mount. The screws are really tight and the 2mm allen key provided by Red isnt perfect and it is VERY easy to strip out the screws. I am assuming once I can figure out a way to remove those screws this wont be an issue becuase I will never over-tighten the screws.
I highly recommend getting a craftsman set of metric allen keys and dont use the 2mm provided in the nikon kit.
