The distance from a camera lens's focal point to its CCD imaging chips with the lens focus set to infinity. Wide angle views use short focal length; narrow field of view (telephoto) use longer focal lengths. Zoom lenses have a variable focal length.

| focal length |
The distance between the film plane and the focal point (optical centre of the lens) when the lens is focused at infinity. The focal length of the lens is marked in millimetres on the lens mount. The principal focal point is the position of best focus for infinity. There are two principal focal points, if a lens is turned around a second focus is obtained. 'Reversed' lenses are often used in close-up Macrophotography because using a lens reversed allows a closer focusing distance. ...
