Camera Focal EquivalenceFocal Length Mm to Full Frame Equivalent Mm At One Inch 13 2mm

Focal length (mm) to 35mm equivalent focal length (mm) for 1-inch sensor 13.2mm

Snapshot

On 1-inch sensor 13.2mm, a 50 mm lens gives about a 136.5 mm full-frame equivalent. Conversion Encyclopedia keeps the same sensor profile across the calculator, common values, and reverse page for this page.

Sensor profile: 1-inch sensor 13.2mm (13.2 mm width, crop factor 2.73).
Example: For 14 Focal length (mm), this corresponds to 38.22 35mm equivalent focal length (mm) on 1-inch sensor 13.2mm.

API, OpenAPI and WebMCP documentation

Explanation

1-inch sensor 13.2mm uses crop factor 2.73 and sensor width 13.2 mm. equivalent_mm = focal_mm x 2.73. For input 1 mm, output is 2.73 eq mm.

Method & Sensor Profile

Sensor basis: 1-inch sensor 13.2mm profile with crop factor 2.73 and sensor width 13.2 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 1-inch sensor 13.2mm, crop factor 2.73, sensor width 13.2 mm.

How do I reverse mm to eq mm for 1-inch sensor 13.2mm?

Use the opposite-direction page for 1-inch sensor 13.2mm 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.
