Three types of electronographic cameras have been designed for different scientific objectives at the CFH Telescope. Two of them are already intensively used and the third one is being completed. The prime focus camera and the cassegrain focus camera have already reached the expected limiting performances such as image quality better than 0.8 arcsec on long exposures, limiting magnitude higher than 26 for accurate photometry, and slitless spectroscopy of quasars fainter than 23rd magnitude. The main purpose of the third camera will be as a detector for the "long slit spectrograph" mounted at the cassegrain focus.
