API, OpenAPI and WebMCP documentation

Explanation

APS-C Sony/Fuji 23.5mm uses crop factor 1.5 and sensor width 23.5 mm. focal_mm = 23.5 / (2 x tan(HFOV/2)). For input 1 deg, output is 1346.41663902 mm.

Method & Sensor Profile

Sensor basis: APS-C Sony/Fuji 23.5mm profile with crop factor 1.5 and sensor width 23.5 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 horizontal angle of view (degrees) to focal length mm?

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

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

Use the opposite-direction page for APS-C Sony/Fuji 23.5mm 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.
