Scratch in rear lens cell!! How can it be reduced or removed?
Scratch in rear lens cell!! How can it be reduced or removed?
I have a scratch in the center outer glass of the rear lens cell on a rather rare lens and am curious as to option for removal via polishing or reduction by same method. The lens --N. Perscheid is the name and that should tell the whole story!! Suggestions and since it is a soft focus portrait lens any image degradation is unseen! J Burke

Don't, you'll change the curve of the cell. The lens --N. Perscheid is the name and that should tell the whole story!! Suggestions and since it is a soft focus portrait lens any image degradation is unseen! Then don't worry about the scratch? Best advice I can give is blacken it with magic marker etc. -- Stacey

I have a scratch in the center outer glass of the rear lens cell on a rather
rare lens and am curious as to option for removal via polishing or reduction by same method. The lens --N. Perscheid is the name and that should tell the whole story!! Suggestions and since it is a soft focus portrait lens any image degradation is unseen! I wouldn't do it strictly on ethical principles, regardless of whether the lens performance will be affected or not. I know you will not attempt to sell the lens without telling the new owner that it was "fixed", but, when you pass on, God forbid, your estate will undoubtedly dispose of it unwittingly without revealing its hidden secret.

Have you checked to see whether it's degrading the image? I was surprised
recently to notice for the first time that I have a fairly large scratch on the rear cell of my 210 Apo Symmar. I bought the lens new about ten years ago and when and how the scratch got there I have no idea but it hasn't affected the quality of the photographs that I can see. "Jos.

Think about it: The scratch is SO far from the plane of focus, unless the
scratch is REALLY huge, it won't make a hoot of a difference. "Shelley" wrote in message news:NlX%c.19676$x12.14887@trnddc05... Have you checked to see whether it's degrading the image?
