Focal length vs focal distance
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. WebFocal length = the distance from the subject to the lens + the distance from the lens to the camera sensor You also need to understand if your lens is concave or convex to …

In other words, focal length equals image distance for a far subject. ... F-stop is the focal length divided by the diameter of the lens. For example, a 200mm f/4 lens will be 50mm wide. Get out your ruler and measure it. 200mm/50mm = f/4.
WebWe would like to show you a description here but the site won’t allow us. WebFocal length is usually measured in millimeters (mm) for photographic lenses. It is not a measurement of the actual physical length of the lens but rather a measurement of the distance from the focal point of the lens to the film plane or sensor. With some lens designs, the focal point of the lens may not even be within the confines of the lens.
