Camera field of view
Compare sensor dimensions, focal length and approximate scene coverage.
A clear answer. Here’s how.
For an ideal rectilinear lens, angle=2atan(sensor dimension/(2×focal length)). Approximate scene coverage is 2×distance×tan(angle/2), using a far-focus model. Also reports the diagonal crop factor and focal-length equivalent against a 36×24 mm reference. Does not model fisheye projection, distortion, focus breathing or mounting compatibility.
