Overview & Features
Sea&Sea 4" optical glass dome port designed exclusively for Canon EF 8-15mm F4L USM* and Nikon AF-S Fisheye Nikkor 8-15mm F3.5-4.5 E ED.
*When using with a camera equipped with an APS - C sensor such as MDX - 80D, vignetting may occur in the four corners when using at the wide end (10 mm) and the shooting distance is short. In that case, use the tele (10.5 mm) or longer focal length.
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
