Quick answer
The GoTough filter adapter system is designed specifically for GoPro HERO cameras using a slim skeleton case, while standard adapters often require a separate mounting frame. If you already use the GoTough protective housing, the GoTough filter adapter offers a seamless fit and direct ND filter attachment without extra bulk.
Understanding the GoTough Filter Adapter System
The GoTough filter adapter system from Fotodiox is built around the GoTough protective lens cap cover and the WonderPana Go ND filter. This system is designed to work with the GoPro HERO3+/4 slim skeleton case, not the standard waterproof housing. The lens cap cover protects the lens from dust and scratches when not filming, and the ND filter slides on over the same mounting ring for shooting.
Because the GoTough system uses the skeleton case, it is lighter and allows better microphone access than the standard housing. However, it offers less impact protection. This tradeoff matters if you shoot in wet or dusty environments where a sealed housing is safer.
Standard GoPro Filter Adapters: What to Know
Standard GoPro filter adapters typically clamp onto the standard waterproof housing or use a separate adhesive mount. They are more universal across GoPro models but add extra weight and can block the microphone or buttons. Many standard adapters lack a dedicated lens cap, so the filter itself becomes the only protection when not in use.
If you switch between different GoPro housings or need to use filters with the standard waterproof case, a standard adapter is more flexible. But if you primarily shoot with the skeleton case for better audio and lower weight, the GoTough system is simpler and more secure.
Tradeoffs at a glance
- Compatibility: GoTough system fits only the HERO3+/4 slim skeleton case. Standard adapters fit the standard waterproof housing and sometimes multiple GoPro models. Choose GoTough if you already use the skeleton case; choose standard if you need housing flexibility.
- Protection: GoTough includes a dedicated lens cap for storage. Standard adapters often leave the filter exposed when not in use. GoTough offers better lens protection when the camera is idle.
- Weight and bulk: GoTough system is lighter because it uses the slim skeleton case. Standard adapters add more weight and can interfere with microphone or buttons. GoTough is better for run-and-gun shooting where every gram counts.
