Front Element Group 3440.jpg

Unscrew the Front element group.
After unscrewing the front group, turn in the set screw
flush with the barrel to prevent damage to the zoom ring tube
during removal.

Why my comment 2x ?? Anyhow, I found out. (No need to remove the element group from the rest.) Using a Ø 70 mm drainage pipe and a Ø 70 mm rubber disk remove the 'name' ring from the front. The first glass is then released. The second glass is (to be *) held in place by a ring with 4 notches to turn it. * Unfortunatly in my case this ring was loose allready, causing the glasses to touch each other (dead in the middle), so: no fungus but damage to both glasses.

I have the same question: how to disassemble the front end to (try to) remove fungus from between the glasses? Thanks! Regards, Michiel.

Peter,
it it possible to further take the front element group apart? My lens has developed some fungus in the rear of the first glass element...
Thank you and congratulations on your excellent work!
