API, OpenAPI and WebMCP documentation

Explanation

Super 16 12.5mm uses crop factor 2.88 and sensor width 12.5 mm. HFOV = 2 x atan(12.5 / (2 x focal_mm)) in degrees. For input 1 mm, output is 161.819446158 deg.

Method & Sensor Profile

Sensor basis: Super 16 12.5mm profile with crop factor 2.88 and sensor width 12.5 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 focal length mm to horizontal angle of view (degrees)?

Focal length mm to horizontal angle of view (degrees) is fixed to Super 16 12.5mm, crop factor 2.88, sensor width 12.5 mm.

How do I reverse mm to deg for Super 16 12.5mm?

Use the opposite-direction page for Super 16 12.5mm 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.
