    Horseman 45FA/45HD - lenses longer than 210mm. with this extended lens board?

    Hi,

    If one reads some of the specifications for Horseman cameras
    listed in the following link:

    http://www.kenko-pi.co.jp/horseman/e/faq_tc.html

    one will find that some lenses longer than 210mm. may not
    be used with the regular lens boards because 'flange focal distance
    is too long', or 'length of monorail is short', or some other
    reasons.

    http://www.kenko-pi.co.jp/horseman/e/lens_list.html

    Are extended boards, like this one, an accesory that may help
    use lenses longer than 210mm.?

    Thank you in advance, kind regards!

    Donít know but Horseman did have a 150mm x 2 adapter to 300mm

    And had an extension back

    I have the ridiculous extension, never used

    And I never found a working x 2 adapter lens

    My solution is another camera

    I like my Horseman no camera does everything

    This extension board may be used only with Copal #0 and #1 shutters. Plasmats are usually in Copal #3 or #3S shutters, making them unusable. Lenses like the Fujinon A and Nikkor-Q and M lenses are in #1 shutters, and can be used. But you should know that when used with extensions, tilting the lens will need refocusing and recomposing.

    I use the Horseman "Teleconverter" but it has no "telephoto" function. The resulting lens needs 300mm to focus at infinity. The resulting 300mm lens is very compact, with all the extra length inside the bellows (there are some on ebay now). Horseman actually does make a true telephoto, but it is 180mm for the 6x9cm camera.

    The "short" assembly of the extension back provides just enough focus length for the 300mm lens.

    Don't forget that the FA and HD are different in this respect - maximum flange-to-film distance for the HD is 249mm, while the FA can add another 23mm with the rear extension feature, which is absent from the HD.

    These are great cameras, but they're not the best tool if you intend to make frequent use of lenses much longer than 210.

    Hi,

    Thank you for your messages : ) !!!

    I had felt attracted to the Fujinon 250mm., f/6.3.
    Hence the use of the extended boards. I may not
    tilt the lens. I would use the lens for portraiture
    mainly. I remember seeing a video where tilting
    was avoided.

    I find the option with the 150mm. a quite good option
    when using the converter. Does it become a bit harder
    (in anyway) to focus when using the 2X converter with
    the 150mm. lens? I think there is a two EV
    compensation when using the converter. I wonder if
    that is more than using the Fujinon 250mm. lens with
    extended boards.

    Thank you again, kind regards!

    Thank

    I have an original Horseman extention board and use it with my Rodenstock APO Ronar 300mm, but for portraits I prefer my Schneider Tele Arton 270mm without extention board, works wonderful on my Horseman HF and it would also on a FA!

    Hi Armin,

    Thank you for your message : ) !!!

    Yes, I had thought on the Tele-Arton
    270mm. as it doesn't need more than
    twenty centimeters to be able to focus
    to infinity. I wondered if it may be a tad
    too long for me, but I think it is the
    best option. There is perhaps no 240 or
    250mm. option to be used with this
    camera. The Tele-Arton 240mm. is not
    good for this camera.

    Thank you again, kind regards,

    Ig
