Review on AFAITH Filter Circular Polarizer Camera by John Jones

AFAITH ND Filters for GoPro Hero 9 Black Pack of 3 Bought for $25.90 in June 2021. These ND filters were specially designed for the action camera GoPro Hero 9 does NOT design and work with other versions of GoPro camera. The filters fit exactly on the existing lens of your GoPro Hero 9 and enable a quick filter change. Other ND filters on the market sometimes require the existing lens to be unscrewed from the camera and replaced with a filter lens. While this is safer and less prone to losing the filter lens, it's also more cumbersome. You have to decide what your own priority is (comfort or secure fit). This filter fits the Hero 9's camera snugly and attaches seamlessly, even when the Hero 9 is in media mode. I might be more worried about mounting my GoPro camera and ND filter on something like a mountain bike, which could cause the camera lens to vibrate. The lenses are made of high-quality glass (not plastic) and filter out sun glare very well. Good value compared to more expensive Revain options.
