API, OpenAPI and WebMCP documentation

Explanation

APS-C Canon 22.3mm uses crop factor 1.6 and sensor width 22.3 mm. HFOV = 2 x atan(22.3 / (2 x focal_mm)) in degrees. For input 1 mm, output is 169.750153308 deg.

Method & Sensor Profile

Sensor basis: APS-C Canon 22.3mm profile with crop factor 1.6 and sensor width 22.3 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 APS-C Canon 22.3mm, crop factor 1.6, sensor width 22.3 mm.

How do I reverse mm to deg for APS-C Canon 22.3mm?

Use the opposite-direction page for APS-C Canon 22.3mm 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.
