FAQ's

Using Polarizers and/or ND Filters

There are several options for using polarizers or filters.

1. Keep the cover "open" in front with your filter instead of the Outex front port for water-resistant/above water use (rain, mist, sand, mud, dirt, etc.).

2. We make flat front ports (below 77mm) that offer external threads (77mm) for filters or polarizers on the outside for a waterproof solution (even underwater). For thread sizes above 77mm we sell an extension for a 95mm external thread so you can use 95mm polarizers or filters.  They are both available in Shop By Parts.

3. You can purchase a Outex Dome port (both/either size would work), then use an Outex Dome clamp to fit/match the lens' diameter size.  In other words, since the lens filter thread is taken/ocupied by the polarizer or ND filter, you'd clamp the Outex clamp on the perimeter of your lens.  Both/either Dome Kits include a clamp (or adaptor). See example image below using an ND filter inside of a Dome.

Using ND filters or polarizers with the Outex waterproof housing system

4. Or you can use them inside the housing if you're looking for waterproofed protection, but with limited access if it's a variable filter.

You can shop for External Thread Front Ports in Shop By Parts
