So, I have this lens and there is a very small bit of fungus on the very outside edge of the front element. I didn't even notice what it was until I looked really close with a magnifying glass. I would like the remove the front element to clean underneath, and I have done so on many lenses before, but I don't see any holes for a spanner or anyway to get it out. Can anyone help who might have experience with the lens or other lenses like it with a similarly mounted front element? Thanks.

Heres what the front looks like, found this image on these forums.

It will probably be one of two methods to remove the name ring, it's glued into position, or you will need a rubber ring with some grip to unscrew it.

Thats what I was thinking, dont have one of those though, I'll have to find a way to make something to do the job.

Well I managed to get the name ring off, but once off I noticed that all the lens elements after the iris are housed together, maybe cemented, I dont know, shitty.

If the spot is really tiny and near the edge and you can't easily disassemble the lens, I'd rather store it correctly (dry, exposed to sunlight and dust free) than risk to damage the lens. You have good chance fungus won't grow.
