1,346.416639 Focal length (mm)

Explanation

APS-C Sony/Fuji 23.5mm uses crop factor 1.5 and sensor width 23.5 mm. focal_mm = 23.5 / (2 x tan(HFOV/2)). For input 1 deg, output is 1346.41663902 mm.

For Horizontal angle of view to Focal length, the active sensor profile determines the conversion constants applied to every value.

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.
