We present an update to the photometric calibration of the COMBO-17 catalogue on the Extended Chandra Deep Field South, which is now consistent with the GaBoDS and MUSYC catalogues. As a result, photometric redshifts become slightly more accurate, with <0.01 rms and little bias in the of galaxies with and of QSOs with . With increasing photon noise the rms of galaxies reaches 0.02 for and 0.035 at . Consequences for the rest-frame colours of galaxies at are discussed.
