Thanks for that. I just figure no point using a good lens if shooting through plastic.

That's not really accurate. As far as image quality is concerned, there is little difference between acrylic and glass, aside from glass domes' higher propensity to flaring. Acrylic domes are easier to scratch if you aren't careful, but they're also easier to polish - glass domes are nearly impossible to fix if you do manage to scratch one. The layer of murky water between port and subject will have a far more pronounced effect on image quality than the difference between glass and acrylic, as will misalignments between dome's nodal point and lens entry pupil.
