Lens Selection Guide
- The focal length of the lens is measured in mm and directly relates to the angle
of view that will be achieved. Short focal lengths provide wide angles of view and
long focal lengths become telephoto, with narrow angles of view. A "normal" angle
of view is similar to what we see with our own eye, and has a relative focal length
equal to the pick up device.
