Hi all
i have a bad cold so I decided to tear down my foggy and hazy 90 elmar from 1958
I got it all apart and cleaned up, the front and middle elements are fantastic, the rear was very oily and hazed over, i washed it numerous times and it appears the coating on it is the problem , its half gone and half of it is murky or decayed . Its not fungus ( I dont think) because it looks like when you remove sticky tape and it leaves a slight residue , and it only shows up after the lens is assembled , weird , it must be once the 3 elements start to do their job it amplifies the problem
Any hints/tips to clean it up further or remove the coating itself? cheers
