Is this true?
And, one of the risks of the proceedure is that the glass can crack. Is there any substance to this?
Lastly, I wouldn't think there would be any way possible to predict the rate of separation once it starts, is there?
I had a "separated" Rodenstock 90 f4.5 back when I first got started in LF. I was told the lens might just as well be tossed into the trash. I did, however, keep the Copal 3 shutter! :) The cells did go into the recycling bin!
It sure did hurt to do that! :>|
