Image circle

The image circle is the cross section of the cone of light transmitted by a lens or series of lenses. When this light strikes a perpendicular target such as film or a digital camera sensor, it forms a circle of light, the image circle. Various sensor aspect ratios may be used which all fit inside the same image circle, 3:2, 4:3, 16:9, etc.
