API, OpenAPI and WebMCP documentation

Explanation

Cinema full-frame 36mm uses crop factor 1 and sensor width 36 mm. focal_mm = 36 / (2 x tan(HFOV/2)). For input 1 deg, output is 2062.59570233 mm.

Method & Sensor Profile

Sensor basis: Cinema full-frame 36mm profile with crop factor 1 and sensor width 36 mm.
Profile reference: focal-length and aperture equivalence use the same crop model, while angle-of-view routes use the same fixed sensor width geometry.
Consistency rule: forward and reverse pages keep the same sensor profile; only the formula direction changes.

Questions & answers

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.
