    Do they come in square shape only and therefore need the holder and adapter ring or can you get circular screw on ones?? If they come in circular/screw on form can anyone point me to where they are sold please. If not, are the adapter rings generic or are they different from lens to lens.

    Sorry for the lame questions.

    Thanks guys
    Martin

    I bought some ND grads a few days ago (haven't used them yet). Whilst I've bought round Hoya filters as a preference for anything likely to stay on the lens for any time (eg UV, polariser etc), I think the square - or strictly speaking rectangular - format is far better for grad filters because you need to be able to slide the filter(& maybe rotate it too) within its holder to align with the horizon.
    The adaptor ring fits the screw thread you'd use for round filters (so they come in different sizes) and has a flange that clips into the bit that holds the square filters themselves.

    Great, thanks for that. It was the adapter ring that was confusing me and basically putting me off the rectangular/holder route.

    The adaptor ring will come in various sizes depending on which filter size you need. I was lucky as both my 10-20 Sigma and my 24-105 Canon are a 77mm fitting. :)
