For 2 Focal length, this profile returns 1.34 35mm equivalent focal length.

Converter Calculator

1 Focal length (mm) =
0.67 35mm equivalent focal length (mm)

Explanation

Medium format 53.4x40 uses crop factor 0.67 and sensor width 53.4 mm. equivalent_mm = focal_mm x 0.67. For input 1 mm, output is 0.67 eq mm.

Focal length to 35mm equivalent focal length 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.
