1 Horizontal angle of view (degrees) =
756.285091 Focal length (mm)
Explanation
Drone 1-inch class uses crop factor 2.73 and sensor width 13.2 mm. focal_mm = 13.2 / (2 x tan(HFOV/2)). For input 1 deg, output is 756.285090853 mm.
Horizontal angle of view to Focal length is profile-bound here: the selected sensor profile controls the mapping used by calculator and reference table.
