How to determine the 35mm equivalent focal length of a lens when used with camera that has an APS-C sensor.

    Multiply the focal length printed on the lens by 1.5 to obtain the 35mm-equivalent focal length of a lens mounted on a camera with an APS-C sensor. For example, if you mount a 50mm lens on an APS-C sensor camera such as the ILCE-6000, you'll get the same view as a 75mm lens on a full-frame camera (50mm x 1.5 = 75mm).

    Note:

    • All manufacturers use 35mm-equivalent focal length to describe the angle of view (field of view) of a particular lens and camera combination.
