I'm upgrading to the Nikon D500 with Subal housing. For various reasons I prefer to buy only one flat port (intention FP75) and a couple of extension rings to give me the flexibility to use both my old and eventually also new 60mm and 105mm lenses (without manual focus gears).
I'd like to check with any Subal users whether the Nikon 105VR fits inside the FP75 (using an extension ring)? I figure it should because 105VR has 83mm diameter while the ports and extension rings seem to have internal diameter of 84mm. That sounds tight.
Can anyone confirm that would be possible?
