just today when i turned the camera on in Apture mode the meter wouldn't move when I changed the apture. it stayed the same from 22-1.8 I switched lenses and got the same thing. I tryed to take out the battries and put them back in, changing lenses, fully charging the battries, etc....it keeps happening and I can't find anything in the manual about this problem. If you are fimilar with it and have a fix that would be great. Also, when I use manual mode and it works fine.
