The item was delivered as described and fully complies with my expectations. Of course one should not expect to get here in the filter quality, which must meet very high standards (as well as, at this price!). At first glance the filter view but orderly process of, and the threads are smoothly and accurately. The vignetting is acceptable for me in the context and also I can note any significant light loss in both UV and CPL. The FLD I have not been able to test, but this is just a nice plus since I Regulate the color distortions by fluorescent tubes etc. eh over the white balance. I will use this filter in my honeymoon, I "good" my (or rather expensive) rather than the local weather conditions (sand, salt water, etc.) wishes to suspend. For me, however, this set is a good alternative and in my opinion to know about vollstens!
