Requiring covariance of Maxwell's equations without a priori imposing charge invariance allows for both spin-1 and spin-1/2 transformations of the complete Maxwell field and current. The spin-1/2 case yields new transformation rules, with new invariants, for all traditional Maxwell field and source quantities. The associated spin-1/2 representation of the Lorentz group employs the Lorentz metric and thus the invariants of the spin-1/2 Maxwell field are analogous to those of its four-vector counterpart, e.g., Φ^2 - A^2, E^2 - B^2 + 2iE ot B - partial0 Φ - nabla ot A. However, traditional field and source quantities are complex and neither charge nor the four-divergence of the potentials remains invariant. Requiring the potentials to satisfy the Klein-Gordon equation equates the Maxwell and constitutive equations with two Dirac equations of identical mass and thus one (complex) Klein-Gordon Maxwell field can describe either one vector boson field or two equal-mass Dirac fields.
