Had a lens error on my Canon PowerShot SD1400 IS. The lens would not retract I saw a bunch of fixes online that did not work. Finally I started fooling around with buttons b/c like all electronics sometimes using combinations of buttons help clear the issue. Not sure if this will work for everyone but worked great for me. I charged battery fully, reseated (take out and put in) the battery and SD card. Then I turned it on again, when the error message popped up I held down the play button that looks like a triangle in a square and the Function set button at the same time and the lens immediately retracted. Then I restarted the camera and it worked properly. Hope this fix helps other's.
