Looking for a 82mm (or larger) to 72mm step down ring with double thread....

Discussion in 'Australia Photography' started by princo coasters, Sep 19, 2007.

  1. G'day!

    I'm wondering if anyone can tell me where I might be able to find a 82mm (up
    to about 90mm) to 72mm step down ring adapter with double thread???

    The application is for mounting a panasonic 16:9 lens (has male 72mm thread)
    to a flat plate, but need a ring adapter that is large enough to be drilled
    when fitted to the lens thread.


    Thanks in advance!!

    Have you looked at a HOYA site. or lookup Adeal site and download there
    catalogue which has the hoya stuff in there. Adeal carry other
    accessories as well.

  4. Thanks!....but.....

    The first link store wont ship to Australia, and the second is a US$100
    adapter....... I need something a lot cheaper, and flat, so that i can
    drill through it and mount it to a flat plate.

    Thanks though for your input!

    Another thought have you looked at what Cokin filters use as adapter
    rings. Or alternate, this type of flat sheet filter.

    What do Zork make? http://www.zoerk.com/

    '72mm step down ring' site:au
    Again, lots of possibilities.

    Cheers

  7. I know how to use google........but I dont think your remark was supposed to
    be helpful

    I have searched a LOT - yes, lots of possibilities, but so far, NONE
    SUITABLE.

    Must have:

    - double thread height
    - thick / fat enough to be drilled and mounted to flat plate to allow
    panasonic ag-la7200 lens to be fitted
    - step down to 72mm from at least 82mm
    - must be flat disc, not conical/tube adapter

    several examples found on EBAY and google such as SONIA and KENKO are too
    thin....HOYA dont make anything either.

    If you have something that fits my above creteria, please post the useful
    link here for all to see.

    Thanks!

    This lens just slides over the front of the existing camera lens.

    so you need a tube which has a 72mm male thread at one end and suitable
    length to slide the panasonic ag-la7200 on to that and its screw holds
    that in place????

    Have you thought of finding a 72mm metal lens hood which is suitable
    outer diameter.

    What is the internal diameter of the lens attachment?

    I may have something suitable. from some old panasonic slide dupe
    converters. they may be 67mm thread which will only need a stepping ring.

    Well there's plenty of Aus sites that'll sell you an 82-72mm step down adaptor. But I doubt you'll find one with whatever you regard
    as double thread height. In any event, even an an 82-72mm adaptor will only give you 3mm or so for drilling. Your local engineering
    shop should be able to knock one up to your specs pretty quickly, though.

    Cheers
