6:48 You should've keep insisting and remove the metal back. That's the correct way to do it. Flipping it and disassemble it from the front is not correct. You don't need to remove the front sticker for this repair.
There is a repair manual in Russian on the internet, it says that you should remove the sticker right at the beginning. He also says that he has repaired several lenses and that his method has evolved. Well, what is the best way to repair the lens now?
@@dorfschmidt4833 I fixed this lens and needed to completely dissembled it (twice). I guarantee removing the front sticker is not necessary. Everything comes appart from the back.
