I don't understand.
The light cone exiting a lens assembly will have a certain value, in
degrees, total or half-angle, as you say, from the perpendicular.
Move the lens along it's axis toward or further away from the sensor, to
exactly cover the corners, it always has the same angle. The only thing
that changes is area of coverage. Not the angle of the exiting light bundle.
If you insist what you say is true, I have misunderstood you. Please
elaborate.
