    I ordered a 55-46mm step down ring from ffordes. I lookes nice and
    made in germany but it has a female 55mm bit and a male 46mm bit.

    My camera has a female 55mm socket and I wanted to get a 46mm lense
    which I assume will have a male 46mm thread.

    As such its the wrong way around. Now did I misunderstand how stepdown
    rings work and ordered the wrong bit or was it misdescribed and I
    should send it back?

    Should I have ordered a step up ring?

    Writing on the ring says "heliopan Nr.194 55/46 Made in Germany".

    Anyway I don't know much about his so any help gratefully recieved?

    Thanks

  2. So it's not just me who makes this mistake. I'm sure ffordes will change it
    for you.

    I ordered a 55-46mm step down ring from ffordes. I lookes nice and

    Yup Ffordes delivered quickly and no doubt will help if their mistake.
    However I need to decide if theirs or mine particularly as if I have
    to get one from elsewere I don't wish to order the wrong bit again...
    When you say mistake do you think I was wrong then?

    Thanks

  4. Don't know, I'm afraid. I've always found the nomenclature confusing in
    this area. You could try srb's webpage for info and/or new item - they
    specialise in lens etc. bits and pieces.

  5. No: Step rings (up/down) have male to fit to camera and female to
    take filter etc. What does it say on the ring, it should say
    55mm-46mm. You appear to have a 46mm-55mm step up ring.
    46-55 step up is a standard size, 55-46 step down is unusual as it's
    not normally recommended to step down by more than 4mm.

    I think if you step down that much you're going to get vignetting.

    That sounds right, though that is a step-up ring.
    Just to clarify - the thread on your current camera lens has a 55 mm
    thread?
    And you want to fit a 46mm filter?

    If so, I dont think it is possible to get what you want - you will get
    'vignetting' in the corners of any pictures if such a thing were
    available - it will be stopping the light getting to the lens at the
    edges.
    You may well have ordered what you thought was right, but Ffordes sold
    the 'wrong' bit as it is such an unusual request, and they thought you
    couldnt possibly want a 55-46 step-down ring.
    They'll give you a refund I'd think - they are pretty reputable.

    Right, thank-you for all replies, very helpfull. It does look like
    they mislabeled it as a step down when it is a step up ring. I will
    email them and see what they say.

    As to suitability it is for a stop gap test of a fisheye lens. If I
    worry about anything it is the weight at 500g. It will go on a digital
    camera so while the thread around the barrel is 55mm the actual lens
    is a bit smaller and any additional vinegetting I hope I can just use
    the optical zoom to avoid. Anyway its a stop gap, I just want to see
    how well the fisheye works before investing in a nikon coolpixmade to
    go with it properly. Worth £10 of adaptor bits to experiment with
    first I think.

    Thanks a bunch.

    Well Raynox's fish eye has a 58 mm thread and warns of vignatting on 49mm
    thread lens.

    I would expect Vignatting on anything less then 58 it just how much you can
    live with.

    Oh just to follow up ffordes replied fairly quick and said they could
    not find the correct ring but sent too others which screwed together
    to have the desired effect. I suspect the label was confusing and they
    sent the right item but it was not what they though...

    Interestingly when I was paying they charged 3 pounds for recorded
    delivery, when they were they just stuck a first class stamp on it...
    Thats life though.

    I attatched by 550 gram fc-e9 fisheye to my fuji s602 and it does
    work, no vingetting, in fact I have to zoom in just a little to fill
    viewer. I get a 183 degree circular image. While its not pin sharp for
    web use its ok and I can cover an entire room with two shots (though
    three gives better quality), so basically a success. Enough that I may
    keep it like this and not bother the extra 300 for a nikon as while no
    fantastic its good enough for this.

    Thanks for all help.

    And well done to ffordes for sorting it out thanks I would order
    again.
