Jodad Posted January 6, 2021 Share #1 Â Posted January 6, 2021 Advertisement (gone after registration) Does anyone know how to remove the back 2 groups of 3 glass elements in collapsible 90 f4. I just bought one of these lenses and trying to clean it. managed to get out and clean the front element and also separated the "head" from the rest of the body but don't know how to remove the back 2 groups behind the aperture blades. Any ideas? Link to post Share on other sites More sharing options...
