I have a x100f. I don’t really use advanced filters but one day when I decided to mess with the miniature filter I saw that there were lines through the image (below). I decided to go through the rest of the filters to see if I had the same problem with all them. Turns out it just a couple others, being dynamic and soft.
I don’t see the lines in any other drive mode, my firmware is up to date. I did some searching and couldn’t find any thing online about it. It seems odd to me that its just those three filters specifically, don’t see how I could have been from physical damage at all. I am just sort of at a loss.
