Came across a video on use of filters…
Came across a video on use of filters and saw the K&F Concept ND and CPL filter combined in one filter and had seen reviews of photographers review so defused to buy one and try it out and I was impressed at the quality of build, costing on filter and ease of use so I went and bought two more as my wife also does photography and we share filters on our various lenses with a 77mm diameter, overall impressed by quality it adds to enhance our photos.
