The stability and geometric quality of a Rollei d7 metric digital camera equipped with a 5 megapixel CCD sensor and several metric features were investigated. From a series of calibration measurements it could be stated that the camera provides quite stable values of the interior orientation parameters. In addition, a narrow nearly circular cylindrical apse of a small church of the Romanesque period covered with frescoes was photographed with the d7 metric. For the evaluation of the photos a new procedure for rectification of cylindrical surfaces was used.
