Hi
I've noticed beginning fungus on the front element and want to try cleaning it. I have removed the name ring but I'm not sure how to continue. Is the ring holding the front element in place to be removed the same way? Do I get a free front element or a whole group? I have searched in the archives but have only found some diagram by Rick Oleson about the 50mm.
Any help would be appreciated. |

I've recently asked Rick about these lenses (I'm currently wrestling with a 20mm), and he's confident that most of them follow a similar construction so his diagram. So you should be able to use that as a basis if you can't find any specific info. Don't try to use the 55mm Micro-Nikkor as a template, though - it's different! |

Thanks, Adrian. Could you please tell me whether the ring holding the front element can be removed in the same way as the name ring? |

Unfortunately I've not got that far - I went in from the back, like the 55mm, and am now in trouble! I need to find an appropriately-sized rubber tool to get the first ring off. Sorry I can't be more help! |

OK, thanks. I used a Ø49 lens hood covered with a rubber glove (!) for removing the name ring. Good luck!
