    Default regarding camera lens filters

    hey guys

    was reading this book, came across this filter called neutral graduated filter...

    can someone tell me what's the difference between that, neutral density filters and polarising filters and UV filters?

    thanks!

    My UV filter seems to have some slight smudges which I can't remove by wiping with lens fibre cloth. The filter came with a 2nd hand lens I bought. I have never drop the filter before and l always blow and wipe the filter after use. Why will there be unremovable smudges? Is there anyway I can remove the smudges on the filter? I am thinking of using lens cleaning solution on my fibre cloth to try to see whether i can wipe away the smudges. Will be of help?

    If I'm not mistaken, when there is a build up of smudges or funus, it is often due to the fact that there is some blemish on the filter surface itself and the chance of it recurring back at the same spot is very high.

    As for Hoya, some users do not like them due to the build quality, it often has free play between the glass element and the frame. Cleaning it is also not so easy as compared to say a Nikon NC or a B & W one.

    Hoya and Kenko are the same, just different brand in different countries.
