Useful addition to my Go Ultra set of 4?
The K&F CONCEPT Go Ultra CPL ND filter set came with a plastic case and cleaning cloth. The filters appear to me to be perfectly processed. They are easy to attach to the Go Ultra: Just unscrew the standard attachment from the lens and attach one of the ND filters or the CPL. They fit perfectly, but are significantly larger than the original. So there may be a problem with additional cases or holders for the Go Ultra, as they stick out over the edge. The CPL filter, as I know it from large ones, can be adjusted simply by turning it. The ND filters darken according to the values. This is a useful addition for more demanding video recordings with the small action camera. I'm happy so far.
