The photographic results are quite good and I can agree with the other reviews with 5 stars only ...
However, the filter tilting really very easy. This makes some very awkward with the "Stack Cap". If you are traveling outside and the filter with each tilt which is already quite cumbersome. In one hand, the two filters that are not required in the other, the one needs and the leaves but not detach from the cover. When trying to solve the a filter, the filter then I fell down, fortunately only on the stack-cap side. The filter was luckily unharmed.
The filter cant really very easy. One can very easily turn on, especially on the underside of the cap sits very close and can be almost impossible even after a slight tightening solve. With a narrow blade it was ultimately already, but that should not be the intention, at this price you should already expect a clean finish.
