We consider the model of a massless bosonic photon field interacting with a fermionic Dirac field of mass $M$ in the charge $Q = 1$ sector, described by the self-adjoint Hamilton operator $H_M$. The non-relativistic limit $M \to 1$ of the resolvent $(H_M-z)^{-1}$ for appropriate choice of spectral parameter $z \in \mathbb C\setminus \mathbb R$ is studied.

We discuss the rise of the one-particle Pauli-Fierz operator as the effective Hamilton operator in this limit. The emerging error terms as well as their physical interpretation are also treated.
