Review on Enhance Your GoPro Footage with CamKix Cinematic Filter Pack: Compatible with GoPro Hero 4 and 3+ - Includes ND Filters (ND2/ND4/ND8/ND16), UV Filter, and Cleaning Cloth by Sean Copeland

I am writing this review because I am completely satisfied with the product. I use them on a GoPro Hero 4 and a Campark 4k on my aerial camera drone. I had to make small modifications to the Campark action camera to get these filters to fit. These filters do what neutral density filters are supposed to do, with the right camera and exposure settings. They help create the motion blur I want and have completely removed any minor jelly effects I get from time to time. The aerial shots I take with these filters look crystal clear at 4k@30 and I am very happy with this product. My drone is carefully tuned for aerial photography and I use a high-precision Walkera G-3DH 3-axis gimbal, which I also fine-tuned.
