Ross Wide Angle XPres coverage?

Discussion in 'Large Format' started by de_carney, Nov 6, 2001.

  1. What is the coverage of an old (brass barrel mounted) 12"/4 Ross Wide Angle Xpres? Does anyone have a list of coverages for other Ross wide angle lenses?

    <p>

    Thanks in advance for your replies...
     
  2. Wooden's Large Format Optical Reference Manual lists a 12" f4.5 Ross
    Xpress and indicates that it covers 8x10 with an angle of view of 58
    degrees. There is no listing for a 12" f4 Wide Angle Express, but I
    would guess that it also covers 8x10.

    <p>

    Regarding the second part of your question, Wooden lists five Ross
    wide angle Express lenses:

    <p>

    (1) 4" f4. covers 4x5 with an angle of view of 70 degrees;

    <p>

    (2) 4 3/4" f4. covers 5x7 with an angle of view of 70 degrees;

    <p>

    (3) 5" f4. covers 5x7 with an angle of view of 70 degrees;

    <p>

    (4) 5 1/2". covers 5x7 with an angle of view of 70 degrees;

    <p>

    (5) 20" f4. covers 16x20 with an angle of view of 70 degrees.

    You may also want to look at the Bostick-Sullivan web page which lists
    coverages for a variety of older lenses including Ross. See:

    I hope this helps.
