API, OpenAPI and WebMCP documentation

Explanation

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

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

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

Use the opposite-direction page for Medium format 44x33 to convert 35mm equivalent focal length (mm) back to focal length (mm) with the same sensor assumptions.

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

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