API, OpenAPI and WebMCP documentation

Explanation

Medium format 44x33 uses crop factor 0.79 and sensor width 44 mm. focal_mm = 44 / (2 x tan(HFOV/2)). For input 1 deg, output is 2520.95030284 mm.

Method & Sensor Profile

Sensor basis: Medium format 44x33 profile with crop factor 0.79 and sensor width 44 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 Medium format 44x33, crop factor 0.79, sensor width 44 mm.

How do I reverse deg to mm for Medium format 44x33?

Use the opposite-direction page for Medium format 44x33 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.
