The glass front element is flat so as not to correct for the underwater size distortion that makes everything appear 25% larger and closer. Therefore, the port provides ample magnification for detailed close-up images. Additionally, the glass features an anti-reflection coating to help prevent lens flare when shooting in bright light. The 67mm front threads allow for the attachment of optional, external color-correction filters or accessory wide-angle or macro lenses.
Built for durability, especially resistance to corrosion by seawater, the port body is crafted from polycarbonate. As a bonus, a microfiber cloth is supplied for keeping the glass clean, clear, and scratch-free.
