We present a measurement of the Z$\gamma$ production cross-section and limits on CP-conserving anomalous ZZ$^*\gamma$ and Z$\gamma^*\gamma$ couplings for form-factor scales of $\Lambda$ = 750 and 1000 GeV. We collected 138 (152) candidate events in the ee$\gamma$ ($\mu\mu\gamma$) final states using 324 (286) pb$^{-1}$ of p$\bar{\rm p}$ collisions at $\sqrt{s}$ = 1.96 TeV. 95\% C.L. limits on individual anomalous couplings are $|h^Z_{30}| < 0.21$, $|h^{\gamma}_{30}| < 0.22$, and $|h^{\gamma, {\rm Z}}_40| < 0.019$ for $\Lambda$ = 1000 GeV.
