Pop-up flash will not activate!
EOS 7D--After shooting with my 580EX Speedlight the pop-up flash no longer works. It appears the microswitch under the left side of metal potion of the hot shoe is depressed thus locking out the pop-up. It thinks it still has an external flash in place. Is there anyway one can get the microswitch to return to its normal position? Though it is under warranty I have not time to send it in for repairs as I use it almost every day. roisenp
