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 = equivalent_mm / 1.5. For input 1 eq mm, output is 0.666666666667 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 full-frame equivalent mm to focal length mm?

Full-frame equivalent mm 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 eq mm 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 35mm equivalent focal length (mm) with the same sensor assumptions.

Can full-frame equivalent mm to focal length mm replace full lens-design simulation?

No. Full-frame equivalent mm to focal length mm provides framing and geometry approximations, not full optical-model behavior.
