I've been re-calibrating using 625 silver-oxide batteries from http://photobattery.com/PX625.html. The Canonet seems to have voltage-limiting circuitry so the higher-voltage battery works well. The 625 alkaline might be fine for the Canonet even as the voltage drops. Doug Herr Birdman of Sacramento http://www.wildlightphoto.com
