After a test on a Nikkor 18-105 my wife I could not detect any flaw of this filter. The filter is very well made and quite usable for 10 euros as a lens protector of inexpensive lenses. It is very narrow and not as wide as in the Produktbild.An a thousand euros lens I would not recognize him anyway because me there simply is no trust, where one yet knows that except the name was not much left of Polaroid , In the high-priced glasses it makes then also nothing more from when you previously screwed a trusted B & W filter for 50 Euro.
Conclusion: Very precise cut filter that does the job, little cost and in my eyes as a lens protector for inexpensive lenses quite good for before getting even cheaper goods Noname attacks. As it is with the compensation, I can not judge, but the pictures are in any case with filter no worse than without. Any mirroring stories, as described here, I can not understand.
