In a ray diagram for a camera the focal point is in between the lens and sensor, is this not wrong?

So I've read when the camera is correctly focused the focal length is the distance between the sensor and lens. But when drawing a ray diagram for the object, lens and sensor the the focal point ends up inbetween the sensor and lens.

Also when considering the object as a point it would make sense that the rays from that point all converge on the the sensor behind the lens to give a sharp image. So if the point is far away the rays will come in parallel and converge at the focalplane. It all makes sense but I just don't understand ray diagrams.

• FYI: The "focal length" of a camera lens is the distance between an arbitrary "node" within the lens and the plane on which parallel rays entering the lens are converged. (photo.stackexchange.com/a/22197/51833). That is to say, it's the distance from the node to the sensor when the lens is "focused at infinity." In order to focus on a closer subject, the lens must be moved further from the sensor. Commented Apr 15, 2022 at 14:08
