We carried out a study of photometric variability of the blazar 1ES1011+496 using the 1.20m Oskar L¨uhning telescope located at Hamburger Sternwarte Institute, Germany. This object has been detected at hight energies (~ 200GeV), so it is of interest to characterize its behavior in the optical range. We obtained the light curves in B, V and R bands through differential photometry, with a time resolution of 15 minutes over 8 nights. We did not detect inter-night variability, but we detected a marginally significant variability in temporal scales of a few days.
