Ross Wide Angle XPres coverage?

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...

 

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.
