    Default Dismantling CPL filter

    I open this new after reading 2 forums on filter.

    Has anyone open up a CPL filter using non-destructive way?

    I have searched internet & Youtube, can't find any.

    I have 2 old CPL filters.
    One has a small, fine thread-liked stuck in between 2 glasses.
    The other lagi worse. It has some kind of dried out either cleaning or soapy solution marks inside one of the glass.

    Thank You

    First filter can still be used. 2nd filter I think is "gone" Remove the retaining ring and the glass will pop-out.

    Check how the glass is held in place. Some filters use a spring ring which can be taken out.

    Try this :

    Some manufacturers may use double notched rings instead, like this one :


    Either case, be careful not to scratch the glass.
