    Re: Super Angulon 90 XL Brass Shim

    Shoot some shots at f22. If performance is not what you expect then the lens probably is missing required shims or has been abused.
    One sure sign is if the aperture scale is wrong.
  4. Re: Schneider 90mm f8 in Sinar DB in copal shutter?

    0 shutter. The proper aperture scale is easily added as the two scales on the shutter are held on with 2 small screws.

    Why? If you use the correct lighting they are easy to use.

    Re: 300mm Rodagon with Slight Edge Fungus

    The requirements for spacing and alignment are much more demanding then simply replacing them.

    Re: 300mm Rodagon with Slight Edge Fungus

    Assuming you get it apart, how would you assure proper centering and spacing when you put it back together?

    Re: Linhof Serial Numbers

    My records start in Nov 1946 and your camera predates that. So I can’t tell you.

    Kenny was using an old Super Technika IV when one day, just after he sold his ranch in GA, I got a call from John that Kenny needed to buy a used Folding Focus Hood for that old Technika.

  13. Re: Mystery Kyvytar 240mm f/6.8 in Copal #1

    But if you could mount it in that 0 shutter it would no longer be a 300mm 4.5 lens.

    Re: Fujinon 300mm & 360mm W puzzle

    Perhaps you would like to explain why the image circle increases as one stops down or focuses closer then infinity. Per manufacturer’s spec sheets.
  22. Re: 4x5 Portrait lens recommendation with "classic" look and feel

    “ Solution to the lens in barrel "problem" became the Sinar shutter about four decades ago.”
    Try 6 decades ago. I used it in my studio in the 60s.
    The original Sinar shutter was introduced in 1951.

    Re: Fujinon 300mm & 360mm W puzzle

    Check Rodenstock specs. Long lenses in barrel have, with some lenses, larger circles then the same lens in Copal 3 shutter.

    Sorry, there is no wiggle room. The distance from the top to the bottom of the gg is too great.

  34. Re: What’s your most “unpopular” opinion about LF?

    Unless your camera has axis tilts and swings.
  35. Re: What’s your most “unpopular” opinion about LF?

    And that makes the camera yaw free when used on it’s side as then the swing is beneath the tilt.
  36. Re: What’s your most “unpopular” opinion about LF?

    Rear swing does not create distortion. But just like rear tilt it controls subject shape.
