美[lɛnz ˈfokəl lɛŋkθ]透镜焦距 [例句]The f-ratio describes the relationship between the lens diameter and the focal length and is calculated by dividing the focal length by the diameter of the lens.光圈值描述了镜头直径和焦距的关系，焦距除以直径便...
When picking a lens, one of the first things you must decide on is the focal length or focal range that you want. This is because the focal length describes the angle of view, i.e., it tells how much of the scene in front of you the lens can capture....

The focal length of a lens is the optical distance (usually measured in mm) from the point where the light meets inside the lens to the camera’s sensor. “You can zoom in on your phone, but that’s not changing your focal length. That’s just cropping your photo before you actually...
The focal length of a lens is the distance between the lens's optical center (or principal point) and the image sensor or film when the lens is focused at infinity. In simple terms, it is the distance from the lens to the point where parallel rays of light converge or appear to diverg...
The focal length of a lens can usually be found on both the side of the lens housing as well as around the front element, such as the “50mm” seen on thisCanon 50mm f/1.8 STMprime lens. A 200mm telephoto lens will have an optical center 200mm away from the sensor, and the 14mm...
