I have recently taken purchase of the Zen dome port for my Epl-2 &epo3 housing &9-18 lens.To get a better understanding of the depth of field characteristics of that lens (on land /in air) I downloaded a depth of foeld calculator for my tablet (Indie Film Gears DOF Calculator).Very interesting. My question is firstly, does a dome port give you the same angle of view underwater as the lens would have topside ? Secondly, if it does ( as claimed) can you assume that the lens would now also have the same Depth of field underwater as topside, or does the effect of the dome port play with actual distance relationships and totally destroy this relationship.
Cheers.
