タイトル:

Disassemble front element of Ricoh Auto Rikenon 400mm F6.3 Lens

テキスト:

I've got a fungal growth inside of the front element.

I have read the cleaning answers given, and am quite prepared to undertake it. However the sealing ring does not have any holes on/in it (just writing) for a lens spanner, consequently there is nothing to get a grip on and  have failed in all my attempts to unscrew it.  This of  course this means I can not remove  the front lens so as to access the fungus in behind.

My question: How do I remove this sealing ring ?

P.S It is definitely screwed in - I think.

Camera Lens
