This kit has just about every filter you need to prescribe to the 180 rule which requires setting your shutter speed to double your frame rate. This ensures you can maintain more natural motion blur than what is normally experienced with action cameras. In addition to the the ND filters you get a CPL which aids in minimizing reflections off glass and water surfaces. Bear in mind that these are snap on filters that cover the existing lens. These are definitely quicker to deploy than their screw on counterpart. They sit nice and tight on the existing lens but you then have two sets of glass over the internal lens of the Action 6 which might degrade your image and if you do extreme action sports (Mountain Biking, Motocross, etc.) these have a slight chance of popping off during strenuous activity. These are best If you just are using your camera for vlogging and BTS shots, they are much easier to deploy and remove and eliminate the risk of dirt/dust lodging on the interior lens. K&F is certainly my first choice in filters for all of my cameras and they offer quality product at different price points. They provide some of the best value when it comes to filters IMO.
