    My point is to just try filling the scratch, and don't take it down with you if you dive on the Titanic... ;-)

    Or not. It is a variable soft focus lens that I modified to remove limits. Who knows?

    I'd do a lot of experimenting in fixing a wide variety of scratches with a variety of techniques on cheap UV filters before trying it even once on a good camera lens.

    Filters are made of a specially produced glass to keep both their surface planes strictly parallel. I think after reading this thread filter manufactures will take the LFPF much more seriously, to the point of fearing our secrets. (And that I don't say anything about lens manufactures)!

    Much better than polishing lenses, IMHO...

    Seems to me that trying to polish out a scratch with rouge is about like trying to level out the grand canyon with a gardening trowel.

    Well, its working - very, very slowly - a smaller, secondary scratch has gone now and the main scratch feels smoother in that its now quite obviously not so distinct running a finger nail over it. As I keep explaining, doing nothing is not an option. Leaving a scratch in place on a piece of glass subject to pressure is in effect like marking out a sheet of glass for cutting and then applying force to it - its a weak point. So, even if it takes me several weeks or even a couple of months it saves spending €700 on a new port and may provide a future solution for others. My thoughts are that if you think outside the box you might just be pleasantly surprised, continue to think inside it and you will never be surprised at all.
