Diagonal Field of View

What is Diagonal Field of View

Diagonal field of view refers to the measurement of the visible area captured by a camera lens, expressed in degrees.

It is the angle between two imaginary lines extending from opposite corners of the camera's image sensor, passing through the center of the lens and extending outwards to the edges of the field of view. A wider diagonal field of view means that more of the scene is captured in the camera's image, allowing for a larger area to be recorded or photographed. A narrower diagonal field of view, on the other hand, captures less of the scene but may provide greater detail or magnification of specific elements within the frame. The diagonal field of view is affected by a number of factors, including the focal length of the lens, the size of the image sensor, and the aspect ratio of the image. It is an important consideration when selecting a camera or lens for a particular application, as it can affect the composition and framing of the final image or video. Overall, the diagonal field of view is a useful measure of a camera's coverage area, providing a standardized way to compare different cameras and lenses and to choose the right one for a given task.
