API, OpenAPI and WebMCP documentation

Explanation

Medium format 44x33 uses crop factor 0.79 and sensor width 44 mm. focal_mm = equivalent_mm / 0.79. For input 1 eq mm, output is 1.26582278481 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 full-frame equivalent mm to focal length mm?

Full-frame equivalent mm to focal length mm is fixed to Medium format 44x33, crop factor 0.79, sensor width 44 mm.

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

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