I got this lens from a charity shop, it’s a healios 44-3. I’ve kept it for years intending to get a camera and adaptor for it one day but it has this sort of cotton strand looking stuff on the middle element.
I know nothing about lenses, is this fixable with a professional clean for example?
Thanks!
Not necessarily, it could be on the surface of a glass element.
I had a similarly vintage lens that had a lens growth, and was able to clean it with alcohol and a cloth.
Not for the faint of heart though, lens are full of teeny tiny screws, and the aperture blades are super light and easy to dislodge.
