I took some measurements from a Rodenstock 240mm Sironar S, I have.

I am trying to understand how much distance I will have in the frame of an 8x10 camera, Landscape.

The specs for the lens state an Angle of coverage of 75 degrees.

I took the camera out and took some measurements:

Lens to Subject = 9ft

Landscape width measured = 8ft 3in

to my Calculations this gives an Angle of Coverage of 50 degrees, not 75...

Is my missing connection, focused at infinity?
