Hi, I'm an owner of a Canon Rebel T3i (600d) and I have an issue with my aperture. I just can't change it BUT only in all photo modes... in video mode everything works. It is not due to my lens because I have the same problem with all of them: a Canon 50mm f/1.8 , a Canon 18-55mm f/3.5 , a Canon 35-80mm f/4 and my Canon 80-200mm f/4.5. I've already updated my camera from 1.0.2 to 1.0.3 and the problem is still here. I contacted Canon too and they sent me the manual with the page for the aperture but I already know how to change it. I hope somebody could help me. p.s.: Sorry for my English, this is not my native language.
