Horizontal angle of view (degrees) to Focal length (mm) for Cinema full-frame 36mm

1 Horizontal angle of view (degrees) = 2,062.595702 Focal length (mm) ยท camera-equivalence calculation for Cinema full-frame 36mm

Direct Answer

On Cinema full-frame 36mm, a 50 horizontal angle of view needs about a 38.601125 mm lens

This result uses the fixed Cinema full-frame 36mm sensor profile (crop factor 1).

To reach 14 Horizontal angle of view (degrees), you need 146.598236 Focal length (mm) on Cinema full-frame 36mm.

Explanation

Formula: focal_mm = 36 / (2 x tan(HFOV/2)). Why: this page keeps Cinema full-frame 36mm fixed, so crop factor and sensor width stay explicit for every calculation.

Cinema full-frame 36mm: a sensor profile with crop factor 1 and sensor width (horizontal) 36 mm, used as the fixed framing basis for this page.

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

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

This route is useful when you know the target horizontal framing angle and need the focal length required on Cinema full-frame 36mm.

This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Cinema full-frame 36mm).

Method & Sensor Profile

  • Model basis: Cinema full-frame 36mm sensor profile with crop factor 1 and sensor width 36 mm.
  • Profile reference: Cinema full-frame 36mm (crop factor 1, sensor width 36 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 horizontal angle of view (degrees) to focal length mm?

Horizontal angle of view (degrees) to focal length mm is fixed to Cinema full-frame 36mm, crop factor 1, sensor width 36 mm.

How do I reverse deg to mm for Cinema full-frame 36mm?

Use the opposite-direction page for Cinema full-frame 36mm to convert focal length (mm) back to horizontal angle of view (degrees) with the same sensor assumptions.

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

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