This kit has just about everything 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 that work as sunglasses for your camera you get a CPL which aids in minimizing reflections off glass and water surfaces. Bear in mind that these are screw in filters so you have to remove the protective lens from the OA6 before you put them on. This will add time to swap, leaves the lens on your OA6 exposed to dirt/dust but from my perspective is a better option in that there is less glass between your subject and the interior lens on the OA6. i would also recommend these over the slip on version for those who really are using their camera in an action setup, these have no chance of just popping off during strenuous activity. Many other filter options for the OA6 slide on which may be quicker but save time 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 product at different price points. They provide some of the best value when it comes to filters IMO.
