Calculate the horizontal, vertical and diagonal angle of view for a lens and sensor.
The angle of view grows as the focal length shrinks, and the effective sensor size from the crop factor determines each axis. Knowing the angle of view helps you predict how much of a scene fits the frame before you raise the camera.
Field of View
Angle = 2 x atan(sensor / (2 x focal length))
Angle = 2 x atan(sensor / (2 x focal length)) The angle of view grows as the focal length shrinks, and the effective sensor size from the crop factor determines each axis.
Knowing the angle of view helps you predict how much of a scene fits the frame before you raise the camera.
This calculator takes 2 inputs: Focal length, Crop factor. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
