    Seiko #00 shutter

    In a old LF Fujinon lens catalog, there is a table mentioning that Fujinon SWD and SW lenses are mounted in #00 shutters, which have a 18mm max aperture diameter. Usually, I read that Seiko or Copal shutters do not exist in #00.

    But they do !
    At least Seiko did #00 shutters, I have one on an old SWD 5.6/65mm.

    It is actually exactly the same shutter as a #0, but the shutter blades do not open completely ! They are stopped at around 20mm diameter, it is obvious when the front lens is removed, but not visible otherwise. Aperture opens completely however.

    This is an interesting adaptation. I would venture that it makes the shutter speeds more accurate at high speed since they don't have to travel as far, as it is not needed.

    I think they changed this to rationalize the production; not sure the improvement in speed made such a big difference between a #00 and a #0 to motivate two different productions. Not to mention the head scratching when mounting a lens requiring a #0 on a #00 shutter and seeing the shutter blades sticking out!

    Some Horseman Topcor lenses were put in these shutters, I have a 90mm that I can't swap the shutter with other lenses because of this and the fact that it has a different thread size.

    I've never read or heard of any Fujinon LF lens in a #00 shutter, but you might find one that someone used on one:

    I have a Schneider Super-Angulon 90/8.0 in a Syncro-Compur #00 shutter. The shutter works perfectly. The only irritating item are that T are missing, so you have to use a locking thread release.


    Are T also missing from the Seiko #00 ?

    Do you have a copy of this that you can share?

    Re: Seiko #00 shutter

    WOW!!! Thanks for that. That's completely new to me!!!

    Is there a date on the catalog/brochure? They are usually on the bottom corner of the last page.

    I know that the Fuji literature has its share of errors/typos/etc., but if this is an error it's a DOOZY. But since you have such a lens -- an f5.6 no less -- it's not an error.

    I'll have to keep my eye open for them.

    Anyone else have a SW (probably only SHORT focal lengths) or SWD with a #00 shutter?

    Fujinon SWD...

    Had a 65mm SWD, was mounted in a Copal# 0, not Copal# 00..

    Never seen a Fujinon view camera lenses in a Copal# 00 shutter.. If Fujinon offered a 47mm SWD then the# 00 shutter makes sense. Never seen a SW or SWD series Fujinon with a focal lenght shorter than 65mm. Typically this series is 65mm, 75mm, 90mm, 105mm, 120mm, 125mm_in# 0 shutter.


    gotta wonder if this is a typo...

    65mm was as wide as Fuji went, but the OP has a SWD 65mm in a #00 shutter -- and Fuji literature to boot.

    I've never seen or heard of this either.

    Can we be the only ones?

    Re: Seiko #00 shutter

    When I do a GOOGLE search for "Seiko #00" or "Seiko No.00", I get nothing. Seems odd to me.
