The OG TEL particularly, the small recessed lens seems to like to collect stuff (including the occasional bug or spider hiding out). I was due anyway but the snow storm made it a lot worse which finally reminded me (but I kept forgetting again until today).
I went around and did my “regular” lens cams too, they don’t get as bad but definitely get dirty over time, especially out in the weather.
OG TEL before and after a Q-Tip with a dab of rubbing alcohol (then dried with the other end). While I generally prefer a good quality microfiber for lenses, I don’t have any microfiber that can get into that tiny spot.
