    For example, a 35 mm lens mounted on a full-frame Canon EOS 5D provides a slightly wide-angle view, while the same lens mounted on an APS-C Canon EOS 400D provides a "normal" or slightly telephoto view. In order to more easily compare lens–camera pairs, it is common to use their 35 mm equivalent focal length.

Its performance is 'better ...

    35 mm equivalent focal lengths are calculated by multiplying the actual focal length of the lens by the crop factor of the sensor. Typical crop factors are 1.26× – 1.29× for Canon (1.35× for Sigma "H") APS-H format, 1.5× for Nikon APS-C ("DX") format (also used by Sony, Pentax, Fuji, Samsung and others), 1.6× for Canon APS-C format, 2× for Micro Four Thirds format, 2.7× for 1-inch ...
