Digital Camera World Verdict

This HD nano Mk II filter is a simply superb circular polarizer. Build quality is epic, light transmittance is around half an f/stop brighter than usual, the glass is toughened and the nano structure coatings are hard as nails. It’s available in a wide range of popular sizes, overall performance is spectacular and it’s well worth the albeit expensive price.
