    Hi people, I'm planning to buy the m.ZD 12mm and I had a couple of questions re: filters.

    I'm going to use the 12mm mainly as a landscape lens and I'm especially interested in shooting scenes with moving water (rivers/streams/waterfalls/coastal), so I'd like to use both a polariser and an ND filter.

    So...

    - How much variation do you get across the frame when using a polariser on a 12mm? For instance, with a full sunny sky. An example image would be great.

    - Does anyone know of a manufacturer that makes a quality, slim, 46mm 10-stop (or thereabouts) neutral-density? It's easy to find slim CPL's - less so ND's.

    - From experience, would a stacked slim CPL and slim ND cause vignetting? For most of my use I'd like to be able to use both together...

    Thanks in advance :smile:

    Stacking on such a wide angle might be tricky...not sure what other filters you have but would you consider a step up ring ?

    I assume with the type of stuff you shoot heaps of in Tassie you would get a lot more mileage out of the CPL so I'd probably get that in a 37mm, a CPL you could almost always keep on the lens for landscape shooting, but a 10stop ND will be used less often and is pretty chunky so sizing up is almost a must for 12mm. It is for my P14 when I stack on top of it !


    In that case I use my 46mm Marumi CPL then use a step up ring for one of my 52mm NDs. On my PL25 it's not necessary but I've found on the P14 it is. The 12mm will be even less forgiving.

    I use the Lee 75 system, so an ND and pola are not a problem. Like all Lee gear, it's not cheap but it works very well. I haven't used it a lot yet but the sky looked fine to me. Here's a link to a shot taken with the pola, but no ND: Big Buttons

    I've considered a step-up ring but the next size up that I have is 52mm and while I can both a CPL and ND in this size, neither is slim and I'm concerned that there would be vignetting. Are you saying that using a step-up ring will reduce the likelihood of this? This could be a good option as there's lots of slim 46mm CPL's about, and then I could stack a step-up on that to my 52mm ND. I've never used one so I'm not sure though...

    Not sure what you mean about the 37mm CPL - m.ZD 12mm has a 46mm ring?


    Thanks for the suggestion. Because of the amount of travel and bushwalking I do, I'd prefer something less bulky than the Lee/Conkin style set-up.

    The Lee 75 system is much less bulky than the full Lee system, and the filters are tiny. I was surprised by how small it was. It's worth a look if anyone in Tassie carries it.

    Aha....sorry mate my mistake, I was thinking of the 37mm filter thread for my O45 !

    Yeah, when I've stacked 2 X 46mm filters on my P14 I've had vignetting, and thats using the ultra slim Marumi SHG CPL. Stacking instead with a 52mm B+W FPro ND the issue went away...the extra 6mm in gained diameter did the trick. Would it also suffice given you'll be shooting the slightly wider O12 ? That I can't say for certain, but given you already have the filters, fork out few bucks for the step up ring and give it a crack.
