9-1/2" f6.8 Goerz Dagor Am. Opt. Co. for 8x10?

Discussion in 'Large Format' started by john_mcdonald, May 4, 2002.

  1. I am just delving into 8x10, and looking for a good moderate wide angle. Does
    anyone have information or experience with the 9-1/2" f6.8 Dagor, in regards to
    image quality and coverage? Or perhaps a more suitable recommendation? Thank
    you.
     
  2. From this site, the lenses that stand out are the Fujinon 250mm f6.7
    (not f6.3), the 240mm g-claron, the 250mm Wide Field Ektar (2nd
    widest), the 210 Angulon f6.8, the 210mm Super Angulon (huge and
    expensive), and the 210 Super Angulon XL (not so huge, but much more
    expensive).

    The 9.5 inch dagor had a published image circle of about 340, which is
    just large enough to cover, but not so large as to give significant
    movement.
     
  3. I would add that the following image circles:

    <p>

    210 Angulon f6.8: 382. 210 Super Angulon: 500. 210 Super Angulon XL:
    500. Wide-field ektar: 420. Fujinon f6.7 250mm: 289 (or 298?). The
    image circle for the 240mm G-Claron is significantly wider than
    published.
     
  4. Hi John,
    Neil's reply on the image circle is useful information, and I would
    like to add some other thoughts to consider. I settled for a 10" WF
    Ektar because of the image circle and relative affordability. I shoot
    BW only and a deep yellow filter would deliver an acceptable contrast
    as this lens is single coated only as are most Dagors, some are
    uncoated I think. Are you planning on shooting landscape where
    usually weight and compactness is more important or architecture
    where a larger image circle is necessary for the rise? Do you shoot a
    field camera or a monorail? I found that on my Deardorff I can get
    enough vertical correction from the Ektar to shoot fairly tall
    buildings and industrial structures. Even when the camera is tilted
    upward and the standards leveled, I normally get bellows vignetting
    before runnning out of the image circle of the Ektar although close
    to it. The bellows get so constricted and it's hard to maneuver to
    movements unless your camera has provision for a bag bellows.
    Anything shorter would be harder and anything wider like the 210
    Super Angulon or XL would be overkill if your camera has the same
    restriction as mine granted you're utilizing the better part of the
    circle. If you don't need that much coverage, the Dagor is an
    excellent performer too. They do better at smaller apertures and some
    are known to have focus shift. The Gold Dot/Gold Rim versions are
    better but command a higher price. If you want to go modern, I would
    go for the Fuji 250/6.7. The modern lenses tend to be slightly
    sharper and of higher acutance from the multicoating except the G
    Clarons which are single coated, nonetheless excellent process lenses
    with big coverage and bigger as you stop down. Just my two cents,
    hope it helps. Best regards,
    Henry
     
  5. Hello, I use my 210/5.6 Caltar-s II (symmar-s), I originally bought
    it for the 4x5 of course, but found that it covers 8x10 and is great
    for landscape work. If I were doing architecture or studio work then
    it would not have enough coverage, but it works great in the canyons
    and mountains of west Texas.
     
  6. Hi John!

    <p>

    I own and use 9-1/2 f6.8 Dagor for my 8x10 Deardorff. Wonderful lens.
    I have the golden dot version. Small, sharp, contrasty with a special
    glow. Enough coverage for 8x10. I usually shoot at f45.

  7. Thanks all, for your helpful replies.
     
  8. John,
    I just purchased a 7" X 17" camera which came with a 91/2" Dagor
    6.8 lens. I shot some film and found that the lens just barely
    covered the 17" diagonal. Dagors are known for huge image circles
    and also can vary greatly from published image coverage. THis lens
    should cover 8 X 10 with no problem. Steve Sherman
