Converter Calculator

1 35mm equivalent focal length (mm) =
0.178571 Focal length (mm)

Explanation

Action camera 1/2.3" class uses crop factor 5.6 and sensor width 6.4 mm. focal_mm = equivalent_mm / 5.6. For input 1 eq mm, output is 0.178571428571 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.
