Port Sea&Sea Dome 100 mm L II Fisheye Glass

100 mm in diameter. The most compact and lightweight optical dome port SEA&SEA offers. Designed exclusively for fisheye lenses.

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.
Uses high quality BK7 crystal glass.

Important info: 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.

Optical Dome Ports come with specially designed and produced dome port cover and port case as standard.
