Top screw-in filters for the Action 6
Since I like to use ND filters for a more natural look when filming, I was eager to try the K&F filters, as the brand is known for its quality, and I wasn't disappointed. The filters come in a very well-padded case with a microfiber cloth and, unlike other screw-in filters, are screw-in. This does have the slight disadvantage that, as the name suggests, you have to screw them on after removing the original lens, but it also means they fit 100% securely, which I particularly appreciate when motorcycling or skiing. Furthermore, there isn't an additional filter element in front of the actual lens, which is generally beneficial for image quality. They are also the same size as the original lens, so a previously purchased lens cap fits perfectly. Overall, I am absolutely satisfied and give them a full 5 stars. Top quality at a good price.
