Aperture f-number to full-frame equivalent f-number at Smartphone 1/1.7" class

1 Aperture = 4.55 Equivalent aperture · profile-dependent conversion · context: sensor profile

Direct Answer

1 Aperture equals 4.55 Equivalent aperture

This result depends on the selected profile context: sensor profile.

For 2 Aperture, this profile returns 9.1 Equivalent aperture.

Converter Calculator

1 Aperture (f-number) =
4.55 Equivalent aperture (f-number, DoF basis)

Explanation

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

Aperture to Equivalent aperture is profile-bound here: the selected sensor profile controls the mapping used by calculator and reference table.

Keep the same profile in both directions to avoid mixing lookup systems that use different size mappings.

Method & Reference (Verified)

  • Method basis: profile-bound mapping; constants depend on the selected profile encoded in the route.
  • Profile reference: sensor profile.
  • Consistency rule: keep the same profile in mirror direction to avoid mixing incompatible mappings.
