Ross Wide Angle XPres coverage?greenspun.com : LUSENET : Large format photography : One Thread
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?
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.
Regarding the second part of your question, Wooden lists five Ross wide angle Express lenses:
(1) 4" f4. covers 4x5 with an angle of view of 70 degrees;
(2) 4 3/4" f4. covers 5x7 with an angle of view of 70 degrees;
(3) 5" f4. covers 5x7 with an angle of view of 70 degrees;
(4) 5 1/2". covers 5x7 with an angle of view of 70 degrees;
(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.
