I have for quite some time and have now made this filter a lot of photos with him. As long as you stand as a photographer in the shade, he brings out colors, which can be described as a post card-compatible. But woe to you get a little Streulich on the filter and the images seem dull and blurred. The stylus to adjust if you had rather replaced by a more grip ring and designed some common facilitated because the pin anyway only interferes with the necessary lens hood. Fortunately, the pin can unscrew easily. The price seems very attractive, but the audience has such a filter employs generally higher claims. Therefore, the expectations are not quite fulfilled. This gives no Preisbrecher but a polarizing filter in a Quallität you would expect at the price. If more grip and smoother adjustment there from me even four stars.
