Overview & Features
Sea&Sea 4" optical glass dome port designed exclusively for Tokina AT-X 107 DX Fisheye 10-17mm F3.5-4.5, for Nikon and Canon cameras.
KEY FEATURES
- Uses high quality BK7 crystal glass.
- Two different anti-reflective coatings are employed to optimize image
quality, one for the exterior and the other for the interior of the
Optical Domes.
- A multi-layer coating is used on the dome exteriors and
the interior of the domes are coated with silicon-dioxide to effectively
suppress flare and ghosting. As a result, the refractive index of each
port is reduced to less than 0.01% and the domes produce extremely
high-contrast images
