The physical camera has a focal length of 1/2.2. There is an error on the french translation.
When streaming or recording, we only use a small part of the full camera (you can see it as a virtual moving camera), which has around 80 degrees of horizontal field of view as of current firmware. As it is a software emulated camera, its FOV could be changed in a later firmware if we feel the need.
When connecting to a Bebop, an ARCommand of class Common.CameraSettingsState.CameraSettingsChanged will be sent by the Bebop. This command contains the FOV, and the maximum tilt/pan angles for the virtual camera (the one used in video mode).
