Hi Chadback
i own a sony P150 and housing
the way it attaches to this housing is via the tripod mount on the bottom of the housing
there is an 'L' shaped piece of metal that is fixed to the tripod mount then the AD mount that holds the lens is also screwed to this piece of metal at right angles which goes over the port of the housing.
it does not connect to the port part just slots over it
the port on this housing has a diameter of 58 mm
if you are practical you just need to find the AD mount for the same diameter of port on your housing and make up a plate to fix to the housing , i would think
there might be areason why they do not make a mount for your camera , it would be worth e-mailing Inon to get some feedback or answers
i will try and put some photos up later for you
