Hi guys,

I recently dismantled this paricular lens since it needed cleaning BADLY.

What i discovered the Fungus which covers 30% of the front glass is betweet these 2 elements (Fotos)

Is it anyhow cleanable?!

It is cleanable if you re-cement the two elements...

How to uncement them and how to cement them back together so i do not have problems focusing or any sort of problems later on?

You may send it for repair but that may cost more than the lens itself.

Here are some guide from different people. Different people use slightly different approach but the principle is the same.

Thank you Sir for your help! Thats cool, at last i know how to separate them now. About alligning them back together.... There is a guy that used UHU glass glue, and the other ones used canadian balsam... Does that make any difference? What should i use? Is the UHU glue easy to remove once i get the alignment wrong? Does the glue/Canadian balsam needs to be spread on the whole surface of the 2 parts?

I think UV glue is more easy to work with.

My friend told me there is lots of time to align the lens after you put the UV glue. However, I never try re-cement myself so I don't know the exactly details. Someone here should be able to tell you more details.

Check out this page too for more infos on UV glue.

UV glue, also known as LOCA glue, would be your best bet. This glue is used between the glass and the lcd on most phones these days because it leaves no imperfections. Here is more info www.vkrepair.com/loca-glue/
