Good lenses are an investment. But one unfortunate drop, and you could completely destroy that beautiful glass beyond repair, forcing you to spend your hard earned money to buy a lens you already have. Alternatively, you could attach a ceramic filter to your best lenses and keep them protected without losing any optical quality. The innovative ceramic technology in these filters makes them 10 times stronger than standard protective filters, so you know your favorite front element is safe from both impacts and scratches. These filters also have a nano-coating that repels dirt, oil, and moisture, keeping your shots free of blemishes. While the filter shown here is 82mm, thread sizes are available from 67 to 105mm.
