Focal Length Measurement. The easiest and fastest way to roughly evaluate a lens focal length is to hold it under a ceiling light. Focal length determines many of the characteristics of the photos you can take as well as the physical dimensions of the lens. Why is focal length important? Focal length is the physical measurement of distance between the lens and the imaging sensor when the subject is in focus. Focal length, measured in millimeters (mm), determines how much a lens can capture a scene. A projection screen (the floor, or the surface table) is under the lens. If you're still craving more, be sure to watch this episode of focused, which discusses lens focal length. Lens focal length tells us the angle of view —how much of the scene will be captured—and the magnification. The focal length of a lens is determined when the lens is focused at infinity. As a general rule, as the angle of view gets wider (and the number becomes larger), your focal length gets shorter and you can fit more into.
