Typical K&F
I already had ND filters from K&F for my Action4, they did excellent work there and they are now also doing that on my Go Ultra, which has replaced Action4 by the way =)
Clear purchase recommendation, the option with the integrated PL filters in particular is worth its weight in gold. By turning, the PL filter is set stronger or less stronger.
