System Information
Windows 1909 (build SO 18363.720):
Graphics card: NVIDIA GForce GT 1030

Blender Version
Broken: Blender 2.80 (sub 75)
Worked: (optional)

Short description of error
The formula used in the addon to calculate the camera angle (line 670) is wrong:

"angle %f\n" % (360.0 * atan(16.0 / camera.data.lens) / pi)

The right formula is:
"angle %f\n" % ( 2 * atan(camera.data.sensor_width / 2 / camera.data.lens) * 180.0 / pi)

I discovered the bug when I tryed to composite Cycles and povray images of the same scene.

Exact steps for others to reproduce the error
In a basic blender file, render a scene with Cycles and the PovRay addon. Compare the two images: the field of view is different.
