I was shooting outside yesterday on AV mode with my LCD screen closed so I didn't see my images untill I offloaded them to my PC. They were all very underexposed which was strange since I was shooting wide open at ISO 400? Anyway I checked my camera and it was showing a shutter speed of like 1/8000 (on AV mode) and I thought that was crazy? In fact I was able to change aperature and shutter speed settings while on AV mode, it stayed that way until I did a re-start on the camera and now its fine. It was behaving like I was on M mode anybody ever experience this?
