Hi all,

The converter lens for my Elmo FPC, is causing a halo effect when I project, lens is clean on outside but when I look inside it, looks like it is frosted if that is correct term.
The plastic ring on one end has two small holes, I am assuming they are for removing the ring so one can clean inside this.

Anyone know what to use to do this, if I am right in what I am saying re the holes.

Thanks in advance.
Phil

Hi Phil...I've notice with the Elmo FP's I've had that lens clouding or fungus is common. A spanner wrench as Martin suggests is the proper tool for removing the ring insert, however if you don't have one you can try using calipers. You have to be careful not to damage the plastic holes in the insert...but it does work.

See the photos in this thread where I demonstrate on a Sankyo lens: http://8mmforum.film-tech.com/cgi-bin/ubb/ultimatebb.cgi?ubb=get_topic;f=1;t=009709

Thanks for replies and suggestions advice, Martin and Janice.

Knew there was a tool, ah re calipers, my brother has one of those, not sure if it can fit small holes, but we'll give it a try.

Otherwise I look for a spanner wrench to fit this lens,

Cheers
Phil
