The Helmholtz-Zentrum Geesthacht, Germany, is operating the user experiments for microtomography at the beamlines P05 and P07 using synchrotron radiation produced in the storage ring PETRA III at DESY, Hamburg, Germany. Attenuation-contrast and phase-contrast techniques were established to provide an imaging tool for applications in biology, medical science and materials science. In the recent years we rebuilt the integration of imaging detectors. This allows the user to choose from a set of cameras based on different CMOS and CCD sensors. Here we will present the features of the different camera system together with the advantage for different applications. Furthermore, we rebuilt the data preprocessing before reconstruction to provide different scanning techniques to investigate samples larger than the field of view of the X-ray beam. Multi-scale tomography is realized by using different setups or to integrate a low-resolution together with a high-resolution region-of-interest invest
