The polarizing filter and the processing are spotless. I have read many times before, that the filter is difficult to move, which is not the case with my. The filter does what it should and you feel and see that you have quality in your hands. The only thing that really drove me almost to madness was that it is nearly impossible against all description streaking brush. If I do something wrong to you please clarify me. I used the filter for the first time on a trip through Patagonia. I put great value on the filter to keep it clean, but still it happened to me that I made a small spot on the edge of the filter when mounting the lens cap. He was minimal, but I wanted with new Tiffen lens cleaning cloths made of paper (dry) remove him anyway. I wiped it and got a huge smear, as if the glass with a layer which attracts Schlieren would be coated. I tried it with a Lenspen. No Chance. But now I had a minimal imprint of my hand on the bottom. The bottom was still impossible to clean. I managed to end up on the application of at least 20 cleaning cloths to filter to get reasonably clean, but you can still see a little cleaning marks when you hold the corresponding filter into the light. I have found with this is that you get it only if you clean with the cleaning cloth "back and forth" rubs (with little pressure). I usually clean my lenses and filters with a circular motion and thereby had never even the slightest problem. When I try on the filter, you immediately see streaks, although the surface in front of it actually had not. Should I wonder if in the remuneration of my filter is some something went wrong and I'm frankly a little disappointed because I had expected more from the MRC make compensation, the cleaning "child's play" (see manufacturer's instructions). I'm really very grateful for any feedback.
