Focal length (mm) to 35mm equivalent focal length (mm) for Compact 1/2.5" class

Snapshot

On Compact 1/2.5" class, a 50 mm lens gives about a 340 mm full-frame equivalent. Conversion Encyclopedia keeps the same sensor profile across the calculator, common values, and reverse page for this page.

  • Sensor profile: Compact 1/2.5" class (5.76 mm width, crop factor 6.8).
  • Example: For 14 Focal length (mm), this corresponds to 95.2 35mm equivalent focal length (mm) on Compact 1/2.5" class.
  • Use the reverse page if you need the opposite direction with the same basis.

Explanation

Formula: equivalent_mm = focal_mm x 6.8. Why: this page keeps Compact 1/2.5" class fixed, so crop factor and sensor width stay explicit for every calculation.

Compact 1/2.5" class: a sensor profile with crop factor 6.8 and sensor width (horizontal) 5.76 mm, used as the fixed framing basis for this page.

Focal length (mm): a camera-equivalence quantity in this family that depends on the selected crop model.

35mm equivalent focal length (mm): a camera-equivalence quantity in this family that depends on the selected crop model.

This route is useful when you know the actual lens focal length on Compact 1/2.5" class and want the matching full-frame equivalent framing reference.

This page is sensor-profile dependent rather than universal because camera equivalence changes with sensor geometry (Compact 1/2.5" class).

Method & Sensor Profile

  • Sensor basis: Compact 1/2.5" class profile with crop factor 6.8 and sensor width 5.76 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.

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 Compact 1/2.5" class, crop factor 6.8, sensor width 5.76 mm.

How do I reverse mm to eq mm for Compact 1/2.5" class?

Use the opposite-direction page for Compact 1/2.5" 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.
