Understanding Camera Zoom & Lens Focal Length

WebApr 10, 2024 · 16mm simply refers to a camera lens with a short focal length of 16mm. That means if you take a measuring tape and measure the distance between the center of the lens and where the sensor of the camera is usually located when the lens is attached, it is equal to 16mm. However, this is not just a normal distance of moving from point A to B. WebA lens’ focal length is the distance between its optical center or “film,” and the point on an image that appears to be in focus. The lens’s focal lens is in millimeter (mm) units, with each number reflecting ten times the previous one. For instance, a lens with a focal length of 28mm is 10 times longer than one with a focal length of 2.8mm.
