SEA & SEA OPTICAL DOME PORT II 100

Designed exclusively for Canon EF 8-15mm F4L USM* and Nikon AF-S Fisheye Nikkor 8-15mm F3.5-4.5 E ED

100mm in diameter. Versatile optical dome port, compatible with various fisheye and wide-angle lenses. Peripheral image quality will better when used with an Internal Correction Lens.

*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.

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.
