mmCalc is a super simple photography focal length calculator. Simply input your focal length, sensor size, and max aperture and well give you what the 35mm equivalent is of that configuration. If the simple calculator doesnt suit your needs, we also offer calculators for crop factor based on sensor size and completely custom lens + sensor crop factor calculations.

mmCalc also provides calculations for medium format and large format sensor sizes.
