Your schematics did the job! Thank you very much, Henry! The rear, 4-th element Which turned with it's convex side facing front. If you say did the third element is cemented, mine has to be split in two, so I have 4 elements indeed tricked me. I clean the elements with propanol each time I open the lens. Now it's as sharp as it should be ... let's say 95% new. Thanks for the tip 0.4mm shim! I'll need this soon, as I trim the rear Further On!
Best regards, Deso
Greetings to Germany !
