And then there is somewhere that report on a shattered front element...
I remember, some years ago, Jim Galli posted some photos of a lens that looked so bad, I would have thrown it away as a total lost cause.
He posted photos of the lens and photos made with the lens.
Amazingly, the photos made with the lens didn't look too bad. In fact, they were shockingly good.
If I remember correctly the title of the post made some reference to an explosion in a pillow factory or some such.
