Excellent product. I sought protection for the lens of my camera pro. This neutral filter is perfect and does not alter the color temperatures. I could buy something cheaper and same pretty much, though I preferred the reliability of the brand Hoya I've never been disappointed. Guarantee of a higher strength of the glass.
The seller is serious. Product packed TB. If I'm not mistaken, he was sent from Germany (usually neighbors Germans are "square"). Receiving the item 2 days before the scheduled date. And I recommend the product and the seller.
