API, OpenAPI and WebMCP documentation

Explanation

Smartphone 1/1.7" class uses crop factor 4.55 and sensor width 7.9 mm. equivalent_mm = focal_mm x 4.55. For input 1 mm, output is 4.55 eq mm.

Method & Sensor Profile

Sensor basis: Smartphone 1/1.7" class profile with crop factor 4.55 and sensor width 7.9 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 Smartphone 1/1.7" class, crop factor 4.55, sensor width 7.9 mm.

How do I reverse mm to eq mm for Smartphone 1/1.7" class?

Use the opposite-direction page for Smartphone 1/1.7" class 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.
