Port Options

The best camera in the world can't make up for poor optics. Poor optical design and materials introduce ‘image killers’ – distortions, aberrations, degraded resolution, or vignetting.  Gates family of Precision Ports are sharp and clear: the finest optics for the finest underwater images.  No image killers. Professional to amateur, super wide to macro, Gates Precision Ports suit a wide range of needs, conditions and experience. Of course all ports are backed by our legendary customer support and the same standard of excellence expected of all Gates products.

SP80-10 Dome Port

The SP80-10 is a 10in / 254mm spherical dome port that, like it's smaller SP80-8 sibling preserves field of view (FOV) underwater for wide to fisheye imaging.  The SP80-10 however, exhibits superior compatibility with rectilinear lenses, mitigating the soft corners classically found with dome ports in general.  This particularly beneficial with certain cinema PL mount glass like Arri Master Primes and Ultra Primes.

The SP80-10 is available in Anti-Reflective (AR) coated glass only.

SP110-12 Dome Port

At a remarkable 12.6 in / 320 mm diameter, the SP110-12 stands alone, a new standard in underwater optics.  Optical glass with anti-reflective coating, SP110-12 is designed for rectilinear cinema lenses, yet equally at home in natural history applications where split shots and close focus are key parameters. ARRI Master Primes, Fujinon Cinema Zoom's and Anamorphic Lenses all benefit from this superior, 'no compromises' Dome Port.

The SP110-12 is available in Anti-Reflective (AR) coated glass only.
