Lens Fogging

by GoPro ‎09-30-2019 08:55 PM - edited ‎01-29-2021 10:48 AM
What's the issue?
The camera/housing lens or front LCD is fogging. This generally occurs when the camera is operating in a colder or high humidity environment, and is especially common when the camera is being used in water. The fogging resolves when the camera and environment are equalized -- similar to how your breath stops fogging your car's windshield once the heater warms up. Fogging does not damage the camera in any way.

Where does it apply?
  • HERO9 Black (with or without Dive Housing)
  • HERO8 Black (with Protective Housing)
  • HERO7 Black (with or without Dive Housing)
  • HERO (2018) (with or without Dive Housing)
  • HERO6 Black (with or without Dive Housing)
  • HERO5 Black (with or without Dive Housing)
  • HERO4
  • HERO3+ 
  • HERO3
  • HD HERO2
  • HD HERO Original 

How to fix it?

If you are using the camera with a housing in an environment where lens is fogging up, you can use Anti-Fog Inserts designed specifically to alleviate this issue. The anti-fog inserts help prevent your camera's housing lens from fogging, even in cold temperatures/humid environments.


There are some additional steps that you can take to stop or minimize the fogging:

  • If you are using the camera in conditions where waterproofing is not needed or where high wind noise is not an issue, then you should open back door of the housing. Using the open back door for the housing will ensure that the temperature inside and outside of the housing is equal. 
  • Turn off any settings that you do not need (Wi-Fi, Voice control, GPS, etc.) as this helps the camera run cooler.
  • Keep the camera as cool as possible if you'll be introducing to a colder environment (ex: if you're going diving, keep the camera in the dive boat's bucket of fresh water for rinsing gear until it's time to use it). If you're at the beach, keep the camera in the shade and not out in the sun. 
  • Ensure that when you are opening the battery door, you have dry hands and that the camera is dry.
  • Use QuikCapture (accessible in the camera's Settings/Preferences menu). This feature turns the camera's power off when recording stops. When the camera is powered off, it does not generate heat which can contribute fogging.
  • To help speed removal of the fogging, remove the Protective Lens and open the battery door in a low-humidity environment (ensure the camera lens is safe during this time). Once traces of fogging have cleared, simply re-attach the Protective Lens.
