Effective focal length

July 13, 2017 by Rod Lawton

The angle of view of a lens changes according to the size of the sensor in the camera. A smaller sensor captures a narrower angle of view and makes it look as if the lens has a longer focal length. So in addition to the actual focal length, the manufacturers will usually quote the ‘effective’ focal length too.
