Trying to help out a friend who at the T5i. When she presses the shutter she gets auto-focus lock but the shutter will not release. Sometimes it will release as normal, sometimes a substantial delay (5 seconds) and sometimes not at all. This happens in any of the automatic modes I tried (P, landscape, sports) in QuikMode and in any conditon, outdoor, indoors. Does not appear to be the focus delaying it as it focuses as normal and I get the lock beep. Shutter just will not release. Any ideas I am missing?
