AFAITH 4-Pack ND CPL Lens Filters for GoPro Hero 12/11/10/9 Black, 4-Pack (CPL ND8 ND16 ND32) Camera Lens Protector Kit Set, Neutral Density Filter for GoPro Hero 12/11/10/9 Black

Had purchased an 52mm adapter for my GoPro Hero 8 but unfortunately doesn't fit the GoPro 9. Bought these and they work like a charm. Would buy more especially if they release stronger ND filters.

AFAITH ND Filter for GoPro Hero 9 Black, 3 Pack purchased for $25.90 in June 2021.WARNING: These ND filters are specifically designed for the GoPro Hero 9 action camera and will NOT work with any other GoPro camera version. Filters are designed to fit snugly over the existing GoPro Hero 9 lens which makes it fast to switch filters. Other ND filters on the market sometimes require the existing lens to be unscrewed from the camera and replaced by the filter lens. While this is more secure and less prone to losing the filter lens, it is also more cumbersome. You need to choose what your own priority is (convenience vs. secure fit).This filter fits onto the Hero 9 camera snugly and has no problem attaching even when the Hero 9 is in the Media Mod. I might be more concerned if attaching the GoPro camera and ND filter on something like a mountain bike which may vibrate the lens off the camera. Lenses are made from good quality glass (not plastic), and do a very good job filtering out sun glare. A good value over more expensive options on Amazon.

This did not fit the hero 10. Way too big

It should let buyers know that these do not fit with the media mod on your gopro 9.

Loose fit. It's an action camera and it will fall off

Says what it does and does what it says. Can’t go wrong here.

Very good filter. Stops the glare
