Crop Factor Calculator
Convert focal length and aperture to their full-frame equivalents.
Overview
A crop factor calculator that converts a lens's focal length and aperture into their 35mm full-frame equivalents. Choose a sensor (or enter a custom factor) and optionally a focal length and f-number to see the equivalent field of view and the depth-of-field equivalent aperture, with a clear note that exposure is unchanged. Includes a crop-factor reference table.
