Converter Calculator

1 35mm equivalent focal length (mm) =
0.21978 Focal length (mm)

Explanation

Smartphone 1/1.7" class uses crop factor 4.55 and sensor width 7.9 mm. focal_mm = equivalent_mm / 4.55. For input 1 eq mm, output is 0.21978021978 mm.

35mm equivalent focal length to Focal length is profile-bound here: the selected sensor profile controls the mapping used by calculator and reference table.
