I have an awesome Canon EOS rebel.....we take a lot of pics with a remote. It's great when we take a pic of just one person in the picture. But when we both get in the picture and press the remote the camera is constantly focusing in and out and not taking the pic. We are looking to take action shots and get both of us in the pics, etc....any camera techs out there that know how I can fix this...! What setting should I be in ? And sometimes we take pics in the dark with just the tv on too...(I know night setting) But that issue does happen at times too. Any thoughts would be great!
