Focal length (mm) to Horizontal angle of view (degrees) for APS-C Sony/Fuji 23.5mm

1 Focal length (mm) = 170.270971 Horizontal angle of view (degrees) ยท camera-equivalence calculation for APS-C Sony/Fuji 23.5mm

Direct Answer

On APS-C Sony/Fuji 23.5mm, a 50 mm lens gives about 26.449102 horizontal angle of view

This result uses the fixed APS-C Sony/Fuji 23.5mm sensor profile (crop factor 1.5).

For 14 Focal length (mm), this gives 80.012512 Horizontal angle of view (degrees) on APS-C Sony/Fuji 23.5mm.

Explanation

Formula: HFOV = 2 x atan(23.5 / (2 x focal_mm)) in degrees. Why: this page keeps APS-C Sony/Fuji 23.5mm fixed, so crop factor and sensor width stay explicit for every calculation.

APS-C Sony/Fuji 23.5mm: a sensor profile with crop factor 1.5 and sensor width (horizontal) 23.5 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 APS-C Sony/Fuji 23.5mm and want the resulting horizontal framing angle.

This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (APS-C Sony/Fuji 23.5mm).

Method & Sensor Profile

  • Model basis: APS-C Sony/Fuji 23.5mm sensor profile with crop factor 1.5 and sensor width 23.5 mm.
  • Profile reference: APS-C Sony/Fuji 23.5mm (crop factor 1.5, sensor width 23.5 mm).
  • Consistency rule: forward and reverse pages keep the same sensor profile; only the formula direction changes.

Frequently Asked Questions

Which sensor assumptions are fixed for focal length mm to horizontal angle of view (degrees)?

Focal length mm to horizontal angle of view (degrees) is fixed to APS-C Sony/Fuji 23.5mm, crop factor 1.5, sensor width 23.5 mm.

How do I reverse mm to deg for APS-C Sony/Fuji 23.5mm?

Use the opposite-direction page for APS-C Sony/Fuji 23.5mm to convert horizontal angle of view (degrees) back to focal length (mm) with the same sensor assumptions.

Can focal length mm to horizontal angle of view (degrees) replace full lens-design simulation?

No. Focal length mm to horizontal angle of view (degrees) provides framing and geometry approximations, not full optical-model behavior.
