I'm wondering if it is safe to use pure 2-propanol (isopropyl alcohol) for lens surfaces. I have used it for my old Switars and an old Fujinon eng zoom, it worked without issues. But I'll maybe shoot a part of a small-budget feature soon (or work as an ac) and must to know if this stuff can harm the multicoating or filter surfaces ( my friends assume that can happen )
(the lens isn't mine, and it is more expensive too, so raping the coatings would be a shame, although I know the lens is already scratched by others )
#It will be about five years old 2/3" Fujinon tv zoom and Formatt filters, I don't remember details.
thank you for answering
