    So I am looking to add a bit of punch in my landscape shots. I need a recommended circular polarizer (i did try a search). Also, I need an ND-Grad filter recommendation- including the right "holder" for it (Cokin P is all I know about). For polarizers, I know there is a large variety of brands and qualities, so the prices must get steep quickly. I also don't have $100 for a CPL. The size I am looking for is 58mm for my Mamiya Sekor-C lenses, and I will buy stopdown rings for my 52mm Nikkors.
    Thanks for any info.

    Depending on how wide your lenses are, the Cokin P filters might not be large enough (risks of vignetting); you may need 100mm wide filters. Also, I find that Cokin ND graduated filters are not truly neutral and sometimes give a purple cast to skies. I use Lee and Hitech filters ND graduated filters and I am really pleased with the results.

    My mamiya lens all take 58mm filters. I got a deal on them at Wolf (Ritz). I just use a plane poporising filter and it works finr, less than 10.00

    I have the Cokin 'A' filters which are a little less expensive than the 'P' 's but get me into trouble sometimes with my 45mm Sekor. I would reccomend the 'P' series as they will not get in the way of your wide angle shots.

    A linear polarizer is perfectly fine. You only need a CPL if you're planning on autofocusing through it. So unless you have a 645AF, you don't need it.

    this is all great news. cokin p series holders from ebay are cheap. linear polarizers are cheap. ND-grad filters are not badly priced either.

    Is it the newer plastic body? If so, it's probably some kind of Super.

    Sounds like my Mamiya M645j or a 1000s or something. There's a review for the M645j I wrote on creativeimagemaker.co.uk . This year at tax time, my local PhD (doctor of photography) prescribed a second body and two more lenses to help getting over my bout with G. A. S. It's recurring. Just got a 4x5.Look out.

    Or metering through it, if the meter cell is behind a beamsplitter. It's because linearly polarized light behaves differently from 'unpolarized' light when it passes through a beamsplitter. Circular polarizers polarize, then effectively depolarize the light, while linear polarizers leave it polarized.

    Best,
    Helen
