API, OpenAPI and WebMCP documentation

Explanation

Medium format 53.4x40 uses crop factor 0.67 and sensor width 53.4 mm. focal_mm = 53.4 / (2 x tan(HFOV/2)). For input 1 deg, output is 3059.51695845 mm.

Method & Sensor Profile

Sensor basis: Medium format 53.4x40 profile with crop factor 0.67 and sensor width 53.4 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 53.4x40, crop factor 0.67, sensor width 53.4 mm.

How do I reverse deg to mm for Medium format 53.4x40?

Use the opposite-direction page for Medium format 53.4x40 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.
