And right there is where this product.
The filter has a very good quality, feels quality, can be very good and fast screwing and unscrewing and what is most important, it helps with the above problems further. Waterfalls can be exposed by the reduced light transmission and longer so hold water courses partially almost evenly milky and portraits now also work under 1/2000 easily recordings at maximum aperture ...
And what I also like ... by the remuneration of Hoya, I have only very little flares, which is not a matter of course for additional lenses!
Overall, I am very satisfied and therefore also give my opinion due to the very ordinary price 5 Stars!
