I have a 40d that I have not used in about 6 months. I have a 7d now and I love it. The problem I’m having is with my 40d. I charged the batters, everything seemed to word fine. I pushed the button to take a picture and the shutter gets stuck! It will not release unless I turn the camera off and take out the battery. I mean everything else works it focuses, and everything. I even updated the software and nothing. WHAT IS GOIN ON? CAN ANYONE HELP ME? I’m glad I have my 7d:o
