Learn how to understand focal length and field of view for imaging lenses through calculations, working distance, and examples at Edmund Optics.
11 lis 2022 · Field of view and focal length are two of the most important concepts when it comes to lenses. While focal length is the defining property of a lens, field of view can vary depending on certain other parameters.
12 lut 2018 · The focal length is related to angle of view, so using a short focal length – ie. wide angle lens / wide angle of view – means a wider view of the scene is captured within the field of view. In my description, “wider view of the scene” is the content captured within the field of view.
The most important thing to remember is that shorter focal lengths have a larger angle of view. Conversely, longer focal lengths will have a narrower angle of view. This holds true for both prime lenses and zoom lenses.
27 lut 2024 · The relationship between focal length and field of view is worth exploring further. As the focal length of a lens increases, the angle of view narrows, resulting in a narrower field of view. Conversely, when the focal length decreases, the angle of view widens, leading to a wider field of view.
Focal length is crucial because it determines the lens's field of view. The longer the focal length, the narrower the area of the scene captured by the lens. This means that a lens with a short focal length such as the Canon RF 16mm F2.8 STM captures a much broader view than a telephoto lens such as the RF 1200mm F8L IS USM .
Field of view defines the maximum area of a sample that a camera can image, determined by the focal length of the lens and the sensor size. Sensor size is determined by both the size of the pixels and number of pixels on the sensor.
