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?
