TRUE FOCAL LENGTH:

Trying to work out the TRUE (as opposed to equivalent) focal length of the 4/3'' camera on the Mavic 3 for GSD calculations, however I'm struggling to find all the parameters, from the spec., to complete this formula: T. Focal Len = (0.5 * Sensor Width)/ TAN((0.5 * H.FoV)/ 57.296).

Can anyone help please? Thanks in advance.
