    Do Hoya circular polarizers have a screw tread on both sides so that you can attach another filter on top of it? I always assumed this was the case but thinking about it the other day I realised I didn't know for sure. Thanks.

    Some do some dont, I had a thin one which did not, but the ones I use now do.

    The Super HMC pro 1 ones do have a front thread.

    The Super HMC pro 1 do but the Super MC Thin and the Ultra Circular Polarizers have no front threads.

    On this subject, can you use a Polariser and an ND Grad Filter at the same time and does this have any advantages.

    I have a few times used the 2 together, beacuse it gives you a further reduction in the stops of light entering your lens, doesn't do any harm, check a few of the recent shots from Padley on my PF, a couple of them had both combined. Try anything once. (almost anything, unless for money)

    Yes you can - I do it quite frequently.

    The ND grad does its job by reducing the exposure on say the 'highlights' to balance your exposure for the 'shadows' and the polariser affects the whole image.

    e.g. ND grad to balance a bright sky with white clouds and the land and using the polariser to enhance the contrast between the clouds and the sky ( make them appear even whiter)

    Note however if ou are taking a manual exposure reading the polariser can result in up to 2 stops loss of light.

    Combining them is also a known trick for lengthening the exposure time if you have something special in mind for which there would normally be too much light at the time of shooting...

    Chris, is the ultra circular polarizer the one from the standard double-coated series?
