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 δz/(1+Z) of galaxies with R ≤ 21 and of QSOs with R ≤ 24. With increasing photon noise the rms of galaxies reaches 0.02 for R ≤ 23 and 0.035 at R ≈ 23.5. Consequences for the rest-frame colours of galaxies at z ≤ 1 are discussed.
