Deep CCD exposures of the optical fields of 19 previously unidentified 5 GHz sources have revealed 10 new optical counterparts, 2 marginal identifications, and 4 "empty fields"; 3 sources are probably radio galaxies where no exact coincidence of the optical and radio positions is expected and only a tentative identification is given. The new optical counterparts are classified as stellar or extended (i.e. as galaxy) according to their optical appearance. Two flat-spectrum radio sources previously identified as galaxies are re-classified as stellar objects with neighbouring galaxies. The results support the view that, down to a limiting red magnitude of 23m, practically all strong 5 GHz sources can be identified and that, even among the optically faintest objects, flat-spectrum radio sources usually have a stellar intensity profile while many steep-spectrum sources are extended.
