From the leaders in underwater optic comes another outstanding hand crafted optical glass dome port. The Zen DP-170 offers another 'right sized' version of their legendary dome port line.
The 170mm size is travel friendly yet maintains the Zen tradition for the finest optical ports available. This multi-coated port offers optical purity, free from chromatic aberation, flare and distortion yielding stunning photographic results. The interior of the dome element is coated with a magnesium fluoride broadband anti-reflective coating to minimize internal reflections from camera lenses, lettering on cameras, etc. which can be problematic when shooting over/under scenes. The exterior is treated with a proprietary scratch resistant coating to control lens flare. This coating yields an amazing 99.7%+ transmissive value for true distortion free images.
Includes protective aluminum shade and neoprene cover.
