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.
Gates Lens Compatibility Reference
FP80 Flat Port
Due to its larger front element, the FP80 supports a variety of medium to macro lenses – including external zooms. A simple, versatile port option. Both Acrylic (Perspex) and Glass versions available.
Material
- Optical grade Acrylic / Perspex (standard)
- Anti-reflective (AR) coated BK7 glass (optional)
Element Diameter / Clear Aperture:
- 7.4in / 189mm
Shades
- W075 (standard)
- Macro (optional)
Depth Rating
- 450ft / 137m
Optical Notes
- Flat ports reduce Field of View (FOV) 20% underwater.
SP80 Dome Port
The SP80 preserves field of view (FOV) underwater, and is ideally suited for wide to fisheye imaging. Medium to macro, too, when paired with a macro zoom lens. Anti-Reflective (AR) coated glass or optical grade Acrylic (Perspex) versions, the latter field serviceable / replaceable.
Material Options
- Acrylic / Perspex
- Anti-Reflective (AR) coated BK7 glass
Element Diameter / Clear Aperture
- 7.5in / 190mm
Dome Spherical Diameter
- 8in / 203mm
Depth Rating
- 450ft / 137m
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.
Superior Rectilinear Compatibility
For medium to wide and fisheye imaging, the SP80-10 excels at rectilniear imaging, particularly with PL mount cinema lenses.
AR Coated Glass
The SP80-10 is made of optically pure BK7 Anti-Reflective (AR) coated glass domes.
Material Options
- Anti-Reflective (AR) coated BK7 glass
Element Diameter / Clear Aperture
- 7.5in / 190mm
Dome Spherical Diameter
- 10in / 254mm
Depth Rating
- 450ft / 137m
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. For medium to wide and fisheye imaging, the SP110-12 excels at rectilinear imaging, particularly with PL mount cinema lenses.
