It is reported on an analysis of electroproduction of light vector mesons at small Bjorken-x (xBj) within the handbag approach. The partonic subprocesses, meson electroproduction off quarks or gluons, are calculated within the modified perturbative approach (m.p.a.) in which quark transverse momenta are retained. The soft hadronic matrix elements, generalized parton distributions (GPDs), are constructed from the CTEQ6 parton distribution functions (PDFs) by means of double distributions. The
