I've asked this question before I wanted to confirm if hairline scratches on the lens of my unit would cause any performance issues. I have the V1 carry case and I always handle my unit with extra care. Some how I managed to get tiny hairline scratches on the lens despite my efforts to minimize this from occurring. They can only be seen under direct sunlight or under a lamp but are invisible in normal lighting conditions. I have OCD with these things of things and wish the lens was made of of gorilla glass. Is this something to be concerned about? I have not seen any performance drop thus far but I worry down the line things could get worse.
