1 Focal length (mm) =
161.819446 Horizontal angle of view (degrees)

Explanation

Super 16 12.5mm uses crop factor 2.88 and sensor width 12.5 mm. HFOV = 2 x atan(12.5 / (2 x focal_mm)) in degrees. For input 1 mm, output is 161.819446158 deg.

Focal length to Horizontal angle of view is profile-bound here: the selected sensor profile controls the mapping used by calculator and reference table.

Keep the same profile in both directions to avoid mixing lookup systems that use different size mappings.

Method & Reference (Verified)

  • Method basis: profile-bound mapping; constants depend on the selected profile encoded in the route.
  • Profile reference: sensor profile.
  • Consistency rule: keep the same profile in mirror direction to avoid mixing incompatible mappings.
