Context : Aims : We present V and R photometry of the gravitationally lensed quasars WFI 2033-4723 and HE 0047-1756 . The data were taken by the MiNDSTEp collaboration with the 1.54 m Danish telescope at the ESO La Silla observatory from 2008 to 2012 . Methods : Differential photometry has been carried out using the image subtraction method as implemented in the HOTPAnTS package , additionally using GALFIT for quasar photometry . Results : The quasar WFI 2033-4723 showed brightness variations of order 0.5 mag in V and R during the campaign . The two lensed components of quasar HE 0047-1756 varied by 0.2-0.3 mag within five years . We provide , for the first time , an estimate of the time delay of component B with respect to A of \Delta t = ( 7.6 \pm 1.8 ) days for this object . We also find evidence for a secular evolution of the magnitude difference between components A and B in both filters , which we explain as due to a long-duration microlensing event . Finally we find that both quasars WFI 2033-4723 and HE 0047-1756 become bluer when brighter , which is consistent with previous studies . Conclusions :
