I read this and thought to myself..... Lets see if what Clive
did was a party trick or real.
I have an A 50mm f1.7 lens with a notchy aperture ring. I
decided to try to repair it, but it exploded when I took it
apart, and will never work again.
How tough is Pentax multi coating?
I decided to find out.
My wife is a smoker.
I asked her to butt a cigarette on the front element of this
lens.
She was less than co-operative at first.
She really ground that sucker out.
The glass cleaned up as good as new, not a mark on it.
I might start cleaning my lenses.
