Source for Quality Step-up Rings

Discussion in 'Large Format' started by jeffrey moore, Sep 14, 2003.

  1. I have six Schneider lenses for my 4x5 which have front element
    threads in sizes from 49mm up to 105mm. All of my round filters are
    105mm. I have put together a hodgepodge collection of step-up rings
    that allow me to use my filters with each of my lenses. However, they
    are mostly generic brands of poor quality, some of which I can hardly
    screw into my lenses and filters. The one Schneider step-up ring that
    I have works beautifully.

    I would like to find Schneider step-up rings in all the sizes I need.
    (I also hear Heliopan's rings are very good as well.) I know both
    Schneider and Heliopan make rings in each of the sizes that I need,
    but for the life of me, I cannot find them. I have tried all of my
    usual sources (B&H, Adorama, etc.) and have had no luck.

    Does anyone out there know of any source for what I am looking for?
    Special order waiting times are not a problem. Thanks
     
  2. Why don't you call Schneider and ask them?

  3. Badger Graphic usually has most of the heliopan rings in stock
    or can get them fairly quickly.
     
  4. I've had no problems with the B+W brand ones. I get them from B&H. Wouldn't say they're anything fancy though.
     
  5. I've got one B+W ring and one Heliopan and the Heliopan seems much better. B+W makes nice filters, but Heliopan's adapter and rings are really top class.

    If you live in Finland, I can help you with spec. order sources. If not, then sorry, I don't know US distributors.
     
  6. Jeffery, try Robin Kanta Photographic Supply at www.photofilter.com

    He stocks the Heliopan step rings and has very good pricing.
     
  7. Heliopan rings are made of brass, all others that I have seen including B+W are made of aluminum. I would recommend Heliopan unless weight is a concern - my 52-67 alu ring weighs around 2-4 grams whereas the Heliopan brass ring weighs 25 grams! Both specific weight of brass and thickness in material makes it substantially heavier. I can imagine that a 105mm stepring in brass would weigh much more.

    Also, brass is not so prone to sticking due to temperature variations as aluminum is.
     
  8. There is/was a company in Los Angeles called Century Precision Optics, if I am correct, that made custom step-up rings for a friend of mine around 1990. He wanted to do the same thing you are looking for but in his case he wanted to go from a variety of thread sizes to Series 9. See if you can find this business, if not perhaps S.K.Grimes can make them for you or any good machine shop maybe.
