Focal Length Vs Focal Distance at Rachel Enderby blog

Focal Length Vs Focal Distance. As you can see from figure 1, a shorter focal length creates a wider angle of view, which means the subject appears smaller in the resulting image. In other words, focal length is determined by the distance between the lens and the image sensor when the subject is in focus. A technical definition of lens size is the distance between the rear nodal point and the focal point of the lens, while the lens is focused to infinity. Focal length is the distance between the lens’s optical centre and the camera’s sensor when focused at infinity, while focal distance is the distance between the camera’s sensor and the focused subject within the scene. Focal length is the distance in millimeters between this point of convergence and the sensor or photographic film of the camera it is attached to. For a defocusing lens (figure 1b), the focal length is the distance from the lens to the virtual focus (indicated by the dashed lines), taken as a negative value. First and foremost, a focal length defines how much of the scene you can capture. Some authors use different sign conventions, however, in particularly concerning the front and back focal length (see below). Focal length measures the distance, in millimeters, between the “nodal point” of the lens and the camera’s sensor.
