Field of view (width × height) of the 45 mm lens by sensor format and working distance

Thin-lens approximation: field of view ≈ sensor size × working distance ÷ focal length, with the distance measured to the front of the lens; closest to reality when the distance is many times the focal length. Sensor sizes are typical for each optical format.
