Received well packaged, very promptly, and no complaints about the quality.
My only observation is after quickly getting dust on it I made the mistake of wiping it with a microfibre cloth. That shouldn't have been a mistake but all of a sudden I was creating smears somehow on the new type of filter surface. What a nightmare to get clean again. (And yes my cloth was clean).
I seem to recall reading somewhere about this type of hoya filter coating being like this, and I also seem to recall reading that smears like this are there on most filters after you've cleaned them, but you just can't seem them as easily.
Bought for protection of a lens mainly and not had much of a chance to use it but I shall update if these 'marks' cause any problems with the images.
