    I got a Konica Hexanon 52mm f1.8 basically for free. It had fungus inside so took it apart to clean it out. Man, what a chore to get it back together without any dust on the elements! How do you do it?

    Finally, the very last two elements of the lens are hooked together inside of this cone thing. Does anyone know how to get them apart? Right now there is water in them because I boiled it thinking the heat would help me unscrew them but it didn't help.

    This is not a life or death matter but it would still be fun to put this together and have a 52mm as opposed to a 50 for those times when I need that little bit more FL. Thanks! :thumbup:

    Boiling wasn't a good idea IMO.

    Meh. If it would have worked, however, I'd be a genius! lol

    I still don't know how to get it apart. :frown:

    Those two elements were probably glued together and never meant to come apart. The glue used is super strength!{although if water got between them then it is failing to a degree} Try to get the water to evaporate. Put that element in a container filled with uncooked rice for a few days.

    If you pop it in the microwave, you'll either get the water to evaporate, or you'll blow the thing up.

    That water will make for cool effects likely not possible with PP!

    Heat does tend do degrade glues so if you are going to blow it up in the microwave might was well try a small torch first - assuming there is not better way the get the job done.

    The other option is to put it in some dessicant for a while (read at least overnight), and see if it will pull the water out.
