Ranging anywhere from 8mm to 2000mm, there is a wide variety of focal lengths for photographers to choose from, each of which are better suited to different genres of photography. This is partly true, but the right answer is;. The focal length of a lens determines what your camera can focus on, and how your images are going to turn out.

Lens focal length and stereo baseline calculator. It does so by computing the desired focal length, the corresponding field of view and the expected depth of field. This measurement is done in millimeters.
