APS-C to Full-Frame Conversion

Calculated using a 1.5x Crop Factor (Sony/Nikon/Fuji)

When using an APS-C lens on a Full-Frame camera (or comparing the two systems), you must multiply both the focal length and the aperture by 1.5 to find the Full-Frame equivalent in terms of field of view and depth of field.
