When using my 7D the other night at an event at my kids school I simply set it to ISO 640 and used the built in flash which I believe was set at 250. I can't recall if I had it set at AV, TV, or Manual.
Today I went to shoot and found that I can't change the ISO or the shutter speed. The ISO is stuck at 640 and the shutter speed at 250. I've tried all the dial settings and I can't change it in any of them. When I go to C1, C2 or C3 it takes on the custom setting, but again cannot be changed from that setting.
How can I reset my entire body back to default and will that help?
Any solutions or suggestions would be greatly appreciated as this is driving me nuts.
Update: I found the "Clear all camera settings", FIXED.
