Linear field of view = 2 (tan (angle of view/2) x distance to subject) common focal lengths and their corresponding fovs. Use this calculator to determine the approximate coverage (field of view) and the ‘ground’ pixel size of a particular lens and camera at a given distance. Then, how can i calculate field of view (along y) ?

Manipulating the fov formula allows the distance calculating in feet from the camera for a required fov width. (1) afov= 2×tan−1( h 2f) afov = 2 × tan − 1. From this definition, it can be shown that the afov of a lens is related to the focal length ( equation 1 ), where f f is the focal length and h h is the sensor size ( figure 1 ). The fov width and height are calculated using the following formulas:

Calculate lens selection according to the size of the area. Since the equation for field of view contains the sensor width, which determines the crop factor of a lens, this is another way to see the effect that the crop factor of a camera has on an image. This yields a value of 0.589+ for your camera, scope and focal.

It should not be confused with the back focal length (bfl) or the flange focal distance (ffd) which are mechanical parameters. The standard quick calculation formula for arcsec/pixel is 206.265*pixel size (um) / focal length (mm). For a given sensor size, h, shorter focal lengths produce wider afov’s.
