I am looking for the dimensions of a few of the Helix underwater extension tube framers. Mine are color coded. The ones I am missing are the white the yellow and the white/yellow. If I knew their size I would like to make them. An alternative would to know the distance to the subject when using a 28mm underwater lens with the 1:1.8 green extension tube the 1:2.75 red extension tube and the 1:1 combination of these two tubes. I have the Nikonos III. I think the sizes are the same for IV and V.
