Hello everyone,
So recently I was out shooting in the cold weather and decided to use my XF10-24 (the old one). Upon removing the rear cover to mount it to my X-T30, I, to my great horror, noticed this bent, transparent line across the rear element of the lens. My friend I was shooting with suspected that it might only be moisture that froze/accidentaly dried on the element. I don't recall ever leaving the lens without cover or actually scratching it with anything at all, I have it only since Christmas 2020. Today I tried to take a couple of photos against the snow to see whether the "scratch" is visible but i didn't spot anything, even at f/18. I've also tried to blow it off and wipe it with lens cloth, to no avail. Can you guys please share your opinions as to what this thing might be? Is it actually a scratch? Should I try more drastic methods, like alcohol, to clean it off? Hopefully you can all see it clearly, I shot it with an old macro setup hooked to my camera.
Thanks to everyone in advance,
Christoph
