    Apart from buying the 'special' Lee kit is there another way to be able to use a CPF and ND grad filters at the same time? I don't know if my CPL is threaded (can't be arsed to go look :blush: ;)) but even if it was by the time I've screwed my square ND filter mount on the CPF probably won't be in the right orientation :rolleyes:

    Yes, buy any one of the 'replica' Cokin P style adaptor holders, relevant sized adaptor ring and a Kood/Cokin CPL. All in it will set you back less than £50 and you'll be able to use the grad and rotate it and the CPL independently.

    Thanks, is this the kind of thing you're referring to? I have a cokin style holder already, but this is the only CPL I can find that I could use in conjunction with it. I couldn't find a cokin kit.

    That's exactly it. It fits into the first thin slot on the holder and can rotate within it. You then drop in the grass in front of it.

    Cool, cheers. Any idea how good it is, I'm a bit skeptical with it being so cheap?

    Funnily enough I got one of those types of sets a couple of weeks ago with a range of ND graduated filters.

    I have only experimented so far not used for any serious shooting. So far so good in the sense that it does what it says. It comes with a range of lens adapters so fits on anything I have.

    Two things to note:

    1. None of my CPLs have threads so no way to combine with one of those unless I use gaffer tape on somesuch ;)

    2. Below about 24mm on the full frame the holder is visible. There are bigger sets to avoid this. Doesn't matter for me but might be annoying if you weren't expecting it.

    Edited - missed out the point I was trying to make - thanks for the tip looks better than gaffer tape :)

    If You're shooting 18mm on full frame you probably won't even get away with a slim Cokin p holder which basically just has a single filter slot in front of the CPL.

    I've never used the Polaroid filter you linked to. I've got a mix of Kood and Cokin filters and think I probably got the CPL from crooked imaging so worth trying them.

    There are large cokin systems, Z Pro? I didn't bother as it looked a lot more and I doubt I will take enough pictures below 24mm to need it. If I do find it limiting I might upgrade :)

    Thanks, good point about the holder. The 18mm eq I used it on before was on the Em10 (9-18mm) and the lens diameter was small so no risk of vignetting/seeing the holder. I do have one on these too, but it only has one slot :rolleyes:

    That's the correct wide angle holder. It has two slots, the thinnest one nearest to the lens is where you fit the CPL then the wider slot in front is for the grad filter.

    Yes, the ribbed edge around the outside of the CPL is about half the thickness of the filter so you drop that into the thin slot and the rest of the filter faces forwards away from the lens. You can then turn the filter within the slot by using the ribs to grip it.

    Curiosity got the better of me so I just took a look. For 18mm you probably need the x-pro which is larger again and the basic adopters and filters are about $280 then the cpl to fit is another $200 on its own.... Yep that's why I stuck with P kit....

    The only issue you might have is that the slim holder may not allow both the CPL and grad at the same time as the CPL can be a tight fit behind the first filter slot.

    D'Oh, that's what I meant in post #10 when I said it only had the one slot ;)

    Think I'd try hand holding the grad filter in front of the CPL before spending £100+ on a holder :laugh:

    Well the CPL certainly fits the holder but you can't then add the ND grad filter. I have a 'standard' non wide angle filter holder which has 3 filter slots so can fit a ND grad filter as well but at 18mm on FF you can see the filter holder on the edges of the frame.

    Back to the drawing board :rolleyes:

    Or shoot from 24mm plus or whatever you need to miss the holder?

    Haha well you can still use it for the 95% of the time you don't need a cpl and nd grad at the same time :) cpl on its own, nd or nd grad on own or no filter for architectural shots etc all no problem ! Methinks you rather enjoy finding the problems :)

    Not at all, shot many a landscape but was just wondering if it was possible. Seems not without spending mega bucks. Would be nice to use both though as I find grad filters pretty essential, but would like that extra punch from CPL without having to 'fake it' in PP ;)

    I agree it's annoying the mega bucks required for those last few mm of focal length :)
