Yes — this port includes its 23mm extension adapter ring.
Acrylic domes give excellent image quality in most conditions and are lighter, more affordable and repairable — light scratches can be polished out. Optical glass is slightly sharper in demanding conditions and far more scratch-resistant, but it cannot be repaired once it is damaged.
The 6″ dome delivers excellent image quality in most conditions while staying compact and travel-friendly, which makes it the usual choice. The 8″ dome gives slightly better edge sharpness and a cleaner over-under split shot, at the cost of size, weight and price.
Optically they are the same dome. The standard carries a petal lens shade, which keeps stray light off the dome and gives the rim some protection — the usual choice for diving. The Surf Edition leaves the shade off: there is less for moving water to push against, so the rig is easier to hold steady in the surf zone and there is nothing to catch when you punch through a wave.
