Frequently asked questions about underwater ports
What is the difference between a dome port and a flat port?
A dome port is a curved (spherical) port used for wide-angle lenses. It helps maintain the field of view underwater while reducing distortion. A flat port is used for macro photography and increases magnification for close-up subjects.
Do I always need an extension ring for my underwater port?
Not always. An extension ring is only needed when your lens must be positioned correctly inside the port. This depends on your lens and underwater housing setup, and can be checked in the port charts.
What is a WACP conversion port?
A WACP (Wet Optics Conversion Port) is an advanced underwater port that combines high-quality optics with a dedicated port design. It delivers superior image quality, minimal distortion and excellent sharpness underwater.
Can I use a wet lens instead of a dome port?
Yes, in some setups you can use a wet lens on selected flat ports instead of a dome port. This allows you to switch between macro and wide-angle underwater, depending on your setup and compatibility.
How do I know which port fits my lens and housing?
You can use the port charts to find the correct combination of port, extension ring and gears for your specific lens and underwater housing.
