Dielectron production in 16 GeV {pi}{sup {minus}}{ital p} collisions is studied using the double equivalent photon method. Equivalent photon spectra of hadrons are calculated analytically in a fully quantal and semiclassical approach. The limitation of the latter approach and the influence of the proton spin-flip terms are studied. Conclusions at variance with those of a recent letter by Bottcher {ital et} {ital al}. are obtained.
