Converter Calculator

1 Focal length (mm) =
174.794876 Horizontal angle of view (degrees)

Explanation

Medium format 44x33 uses crop factor 0.79 and sensor width 44 mm. HFOV = 2 x atan(44 / (2 x focal_mm)) in degrees. For input 1 mm, output is 174.794875595 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.
