Field of view and image circle

Film for 35-mm cameras has a set standard format

(24 x 36 mm), and if the focal distance is the same, generally

the angle of the lens will not change. However, the field of view

is larger than the film, and the part of the view which is larger

than the film is called the image circle (Fig. 6). The field of

view for binoculars is usually everything inside the perimeter

of the image circle.
