Preliminary results from CDF on W + {gamma}, Z + {gamma} and W{sup +}W{sup {minus}}, WZ, ZZ boson pair production in {radical}s = 1.8 TeV {anti p}-p collisions from the 1992--93 collider run are presented. Measurements of the production cross section {times} decay branching ratios {sigma} * B(W + {gamma}) and {sigma} * B(Z + {gamma}) have been obtained. The cross section ratios R(W{gamma}/W), R(Z{gamma}/Z), R(W{gamma}/Z{gamma}) and R(W/Z) are discussed. The authors extract direct limits on CP-conserving and CP-violating WW{gamma}, WWZ, ZZ{gamma} and Z{gamma}{gamma} anomalous couplings. In the static limit, the direct experimental limits on WW{gamma} and ZZ{gamma} anomalous couplings are related to bounds on the higher-order static (transition) EM moments of the W (Z) bosons. Expectations from the on-going and future Tevatron collider runs are discussed.
