if you set your filmback correctly the camera will rotate by itself when
you'll track it (yes I meant the object in 3d space) and if you do the
lineup manually then you'll rotate the camera in 3d space (thats what I
meant) if you have a 6x6 or 36x24, no matter on how your camera is in 3d
space you should and have to respect the sensor size and parameter.
The other reason to have all parameters is because some camera do not use
the full surface of the sensor. For instance the camcorder Canon HF10 has a
sensor of 4.54x3.42. But the actual used surface is 4.54x2.55 (px ratio 1.0,
resolution gate 1920x1080) I would believe the full sensor is used in case
of photo mode perhaps. RED is having same kind of stuff depending on the
recording resolution.
