Focal length (mm) to Horizontal angle of view (degrees) for Micro Four Thirds 17.3mm

1 Focal length (mm) = 166.81097 Horizontal angle of view (degrees) ยท camera-equivalence calculation for Micro Four Thirds 17.3mm

Direct Answer

On Micro Four Thirds 17.3mm, a 50 mm lens gives about 19.630043 horizontal angle of view

This result uses the fixed Micro Four Thirds 17.3mm sensor profile (crop factor 2).

For 14 Focal length (mm), this gives 63.420284 Horizontal angle of view (degrees) on Micro Four Thirds 17.3mm.

Explanation

Formula: HFOV = 2 x atan(17.3 / (2 x focal_mm)) in degrees. Why: this page keeps Micro Four Thirds 17.3mm fixed, so crop factor and sensor width stay explicit for every calculation.

Micro Four Thirds 17.3mm: a sensor profile with crop factor 2 and sensor width (horizontal) 17.3 mm, used as the fixed framing basis for this page.

Focal length (mm): a camera-equivalence quantity in this family that depends on the selected crop model.

Horizontal angle of view (degrees): a camera-equivalence quantity in this family that depends on the selected crop model.

This route is useful when you know the focal length on Micro Four Thirds 17.3mm and want the resulting horizontal framing angle.

This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Micro Four Thirds 17.3mm).

Method & Sensor Profile

  • Model basis: Micro Four Thirds 17.3mm sensor profile with crop factor 2 and sensor width 17.3 mm.
  • Profile reference: Micro Four Thirds 17.3mm (crop factor 2, sensor width 17.3 mm).
  • Consistency rule: forward and reverse pages keep the same sensor profile; only the formula direction changes.
