I have a problem with my Canon t3i:

When I turn it on it starts to do the sensor cleaning automatically and it does not finish to do it more, bone that is marked in the cleaning of sensor, and it does not even allow me to turn it off nor to change of modes, I already tried with all the buttons and nothing, I have to Remove the battery to turn it off. The only way I can turn it on without doing this is in video, and then I can use it in all other modes. Does anyone know why this happens or do you know the solution?

Everything works on the camera except when I depress the shutter release nothing happens. The focus points don’t light up, the shutter does not snap. Have I inadvertently turned something off on the camera body?

Thomas Buzzi - Reply

please help, my camera will not take a picture. Only show’s that NO card, even though I have a memory card installed. Yes made sure the card is not locked, nor installed the wrong way.
