    Becos as u turn ur cpl for polarization u have accidentally turn the filter ring instead of the polarizing ring. Just tighten it back and get used to turn only the very front ring.

    There is only one direction to screw your filter to the lens' filter threads. Make it a habit to use your CPL by turning it to the same direction so that it will never fall off/ unscrewed.

    check the thread on your filter, in might have been "chewed" by the lens' thread when you tried to over-tighten before, or mis-aligned the filter thread teeth but forced it to screw into the lens' thread.

    A (CPL) filter is not a water pipe, don't expect that you can tighten it in similar way - or you'll create some funny trouble for yourself and the lens. The filter threads are NOT meant to be screwed tightly but only to hold the small weight of a filter in place. Which means: if you turn the outer ring of the CPL in the same direction as when loosening the filter - the filter simple will become lose. So make it a habit to turn slowly and always in the same direction as when screwing on the filter.

    You can try bringing it to a shop to help or you can get a more experienced friend to help... We also cannot see what's wrong and tell you what to do to solve the problem..

    I suspect you're referring to the front ring of the cpl? That one can be turned even while it's been attached to the lens. Are you talking about that?

    no,i mean the filter cant tighten to the lens. i think might bcz like wat Octarine's said i mis-aligned the filter thread teeth but forced it to screw into the lens' thread. go the filter "teeth" is being chewed by lens thread.haiz...may b nid to buy new 1 again. tis 1 i just bought last week.

    I too suspect you have mis-aligned the threads of the lens and the filter, and forcefully "screw" in it, which results in it being loose now.

    If im not wrong, what u are saying now is that after u screw to the tightest point, it stills "goes" over that point, which is supposed to be the tightest.

    Good news is, your lens is safe.

    Bad news is, you have to get a new CPL filter if it really bugs you that it cant be tighten. Otherwise, you can just save the money and just work around it.

    Get a new CPL then. Bring yr lens along and ask for guidance on how to screw and use it properly

    you mean you can attach the CPL onto your UV filter but not directly to the lens? That's really odd!
