My Sister has let me have her Canon Reble EOS xs to use for a while. I have a couple questions. What is the "star" button for on the top right of the back of the camera? What is the best film speed to use for out door (sunny) photos? Also I have tried to find an on-line manual for the camera without any luck, does anyone know a link? I have been using a Panasonic FZ-10 for about 8 months and I am curious to use a film camera. Any help or tips on using this camera would help. Thanks.
